Crack Sealing: An indispensable pavement protection procedure

Thursday, May 31st, 2012

There is no argument that all asphalt cement (AC) pavements crack. Cracks in asphalt pavements are inevitable. Neglect and lack of proper maintenance lead to accelerated cracking and/or potholing, further reducing the serviceability of the pavement. There are numerous reasons, which can be broadly categorized, in four distinct classes.

  • Pavement Construction: Examples in this category include flaws in the selection of the right type of asphalt mix, poor mix design, engineering defects, unsuitable ambient conditions, etc. If all of these factors meet design criteria, bpoor workmanship may be considered as a cause for premature failure of the pavement.
  • Traffic Frequency & Load: Fatigue cracking and rutting are the two principal considerations in the pavement design process because they are the primary mode of deterioration of asphalt pavements.
  • Deterioration of the asphalt cement binder, primarily due to weathering under the degrading effects of ultraviolet radiation.
  • Climatic conditions, and pavement expansion and contractions due to temperature variations, and freeze thaw cycles.

Once cracks develop, water easily penetrates into the base and sub-base of the pavement and damages the structural integrity of the aggregate materials. Pavement joint and crack sealants are designed to protect the pavement by minimizing water infiltration and by preventing the accumulation of debris. It has been amply demonstrated and documented that sealing cracks in flexible pavements is a sound preventive maintenance procedure, which adds many years to the life of the pavement, especially when used in conjunction with other preventive techniques such as slurry seal, chip seals and sealcoating.

  • Crack sealing is one of the most cost-effective ways to prolong the pavement life, as much as 3- 8 years.

The Ins & Outs of Crack Sealing :: Pavement Maintenance Tips

Friday, May 25th, 2012

Asphalt may seem tough and durable, but add up the effects of traffic and the elements, and you’ll see how quickly commercial asphalt can wear down. So, like it or not, your asphalt pavement will eventually crack. That is just the nature of asphalt. What you do after your pavement cracks, though, is entirely up to you. And you have two choices:

  1. Do nothing and watch that small pavement crack quickly grow into a large problem. Once cracks develop, water easily penetrates into the base and sub-base of the pavement and damages the structural integrity of the aggregate materials.
  2. Crack Sealing!

Crack sealing is designed to minimizing water infiltration, thus protecting your pavement. In fact, crack sealing is one of the most cost-effective ways to prolong the pavement life. While crack sealing is a more costly option than crack filling, it does provide a longer life expectancy – lasting as much as 8 years or more.

Crack sealing – which utilizes a flexible, specially prepared hot pour rubberized sealant – is considered a permanent treatment and is the only effective treatment for active cracks that contract and expand between seasons.

What is Asphalt Pavement? :: Baltimore Pavement Contractor

Friday, May 18th, 2012

Asphalt pavement is made up of several components, including stone aggregate, sand, additives, and liquid asphalt (petroleum). Once combined, the final product consists of 90-95% aggregate and 5-10% asphalt.

Creating Asphalt Pavement

  1. Predose: The aggregate components of asphalt pavement are weighed using a belt weighing instrument, so that the materials can simultaneously be weighed and taken to the next step in the process.
  2. Drying: A rotary drying drum is used to dry the components at around 300 degrees.
  3. Storage: The preheated or dried components are now sifted and store in silos.
  4. Mixing: The aggregates are then transferred to the mixer. Both the aggregate and binder are mixed thoroughly to form the paving material.
  5. Storage Round 2: After the hot asphalt mix is created it is transported to a heated silo, where it is stored and kept hot until it is ready to be used.

Surface Preparation

There is a great deal of surface preparation that must be performed before the asphalt pavement can be applied. This process includes proper clearing, excavation, ground compaction, and the application of liquid asphalt binder and base materials (compacted stone or asphalt base).

Without proper surface preparation, the life of the paved surface is greatly reduced.

  1. The application of liquid asphalt binder helps the newly paved surface create a greater bond between it and the surface.
  2. The asphalt pavement mix is laid using an asphalt paver and compacted using asphalt rollers. Proper rolling methods have to be used to ensure proper compaction.
  3. Once the asphalt is compacted, it is left to solidify for a minimum of 24 hours.
  4. Enjoy (after you sealcoat your asphalt surface, of course)!

The Basics of Crack Filling: Asphalt Maintenance Tips from My Pavement Guy

Friday, May 11th, 2012

Cracking and asphalt do not mix.

When left untreated, cracks allow water to penetrate deep down into asphalt, softening the stone base. This can lead to alligator cracking / spider webbing, pot holes, and other forms of pavement degradation. The final result: premature failure of your asphalt parking lot / pavement surface and the costly replacement of that surface.

And these conditions worsen as temperatures reach extreme highs and lows.

  • Cracking and Winter Weather: Cracks left over the winter can grow quickly due to snow plowing and the freeze/thaw cycle.
  • Cracking and Summer Weather: In warm and sunny climates, oxidation and humidity have a similar effect.

Asphalt Maintenance Options

  • Asphalt Patching: Patching often doesn’t last and can cost several times what timely crack-sealing costs.
  • Asphalt Crack Filling: Crack sealing can reduce pavement deterioration by restricting water penetration into underlying base and sub-base layers. As part of a preventative pavement maintenance program, crack sealing / crack filling extends the life of your pavement surface.

Benefits of Asphalt Crack Filling

  • Economical Maintenance Technique: Crack sealing provides the most cost- effective use of dollars over time compared to other pavement maintenance techniques.
  • Lock Moisture Out: Filling cracks with either a hot or cold rubberized crack filler helps prevent rain and moisture from flowing through the pavement and causing pavement or base/sub-base failure.
  • Extend the Useful Life of Your Asphalt!

Asphalt Crack Sealing :: Parking Lot Sealcoating :: Professional Sealer

Wednesday, May 2nd, 2012

If you own a business or are a business manager, you knoe nothing looks worse than a worn down, cracked parking lot. It immediately gives your customers/clients the wrong first impression. And you only get one chance to make a good first impression.

Asphalt cracks form very slowly, sneaking up on you until that tiny crack becomes a major problem. Asphalt cracks slowly elongate and widen during weather changes such as freezing and thawing or intense periods of heat.

Dealing with Asphalt Cracks

Monitoring your parking lot carefully and catching these tiny cracks early enough will allow you to patch the problem before it gets any worse.

Asphalt crack sealing is the solution! But in order to get that professional look, you should use a professional asphalt contractor, like PTG Enterprises. They will be able to properly apply your sealcoat, ensuring your parking surface remains crack free for as long as possible.

What is Sealcoating?

Sealcoating is a preventative measure that helps safeguard a parking lot against the harsh effects of gas, oil, salt, weather conditions and oxidation. When applied properly, a sealcoat cures on your parking lot leaving a fresh black finish (protective layer).

How often should you sealcoat your parking lot?

A newly laid asphalt parking lot should be sealed within the first 12 months. Because of the ever-increasing costs of asphalt, many business owners now seal every other year, but the widely accepted time frame is every two years.

If you have any further questions about Asphalt Cracks Sealing, Sealcoating, or have a Sealcoating Project that you need completed, then contact PTG Enterprises aka My Pavement Guy today by calling 410-636-8777 or click here today! The asphalt experts here have managed hundreds of pavement projects and have the experience you need.

“There are many different sealcoating options available to property managers and owners today than there were when I started in the Industry,” said PTG Enterprises owner Patrick T. Gillen III. “This works to the advantage of the property and to the pavement. Now, depending on the current condition of the asphalt, I have the ability to recommend several different options depending on the condition of the lot, previous maintenance schedules and budgets.”

Is Thicker Sealer Better? :: Sealcoating Tips from My Pavement Guy

Friday, April 27th, 2012

The decision to sealcoat an asphalt surface is an easy one. After all, the cost of sealcoating is only pennies a square yard versus repairs and rehabilitation, which can be as much as twenty times higher. What does confuse many business owners and property managers is the amount of sealer needed.

The more the merrier, right? Well, no.

Bigger is not always better. And the same goes for thickness…especially when talking about sealcoating. When it comes to the application of sealer, thicker is definitely not better. Sealer is not meant to be applied in thick patches.

Disadvantages of Thick Sealer

  • Thick coats don’t cure evenly
  • They are prone to tracking and can lead to surface cracks
  • A thicker coat takes longer to cure, which can lead to degradation
  • Thicker coats will reduce the life of your sealcoating

A thick sealcoating will not provide your parking lot with more protection. It actually has the opposite effect. Sealer manufacturers set specific mix designs for their product; when these specifications are not adhered to, the product will not perform as intended.

One of the easiest ways to tell if a parking lot has been over-sealed is if the lot has no texture. An asphalt parking lot should never look smooth, the texture of the below asphalt should be visible.

Avoid the typical more is better thinking —with sealer, thicker is not better!

Using Fiber Reinforcements in Concrete :: Fiber Reinforced Concrete

Friday, April 20th, 2012

The idea of using fibers as reinforcement in concrete is not a new concept. In fact, it has been around since ancient times. Just check out the below concrete fiber reinforcement timeline:

  • Straw was used in mud bricks.
  • Horsehair was used in mortar.
  • In the early 19oos, asbestos fibers were used in concrete.
  • In the 1950s composite materials revolutionized the concept of fiber-reinforced concrete.
  • In the 1960s steel, glass, and polypropylene fibers replaced asbestos.

Common Benefits of Fiber Reinforced Concrete

  • Fibers are used to control cracking due to both plastic shrinkage and drying shrinkage.
  • Fibers reduce the permeability of concrete.
  • Fibers reduce bleeding of water.
  • Certain fibers provide impact, abrasion and shatter resistance in concrete.

Benefits of Particular Concrete Fibers

Polypropylene and Nylon Fibers

  • Improve mix cohesion, improving pumpability over long distances.
  • Improve freeze-thaw resistance.
  • Improve resistance to explosive spalling in case of a severe fire.
  • Improve impact resistance.
  • Increase resistance to plastic shrinkage during curing.

Steel Reinforcement Fibers

  • Improve structural strength.
  • Reduce steel reinforcement requirements.
  • Improve ductility.
  • Reduce crack widths and control the crack widths tightly thus improve durability.
  • Improve impact & abrasion resistance.
  • Improve freeze-thaw resistance.
  • In certain specific circumstances, steel fiber can entirely replace traditional steel reinforcement bar in reinforced concrete.

Steel and Polmeric Fiber Blend

Construction companies tend to blend steel fibers and polypropylene fibers, utilizing the benefits of both products, including:

  • Structural improvements provided by steel fibers.
  • Resistance to explosive spalling provided by polymeric fibers .
  • Resistance to plastic shrinkage provided by polymeric fibers.

Engineered Cementitious Composite (ECC)

ECC is a sub-category of fiber reinforced concrete boasting several impressive benefits, including:

  • 500 times more resistance to cracking than traditional concrete.
  • 40 percent lighter than traditional concrete.
  • Sustain strain-hardening up to several percent strain, resulting in a material ductility of at least two orders of magnitude higher when compared to normal concrete or standard fiber-reinforced concrete.
  • Unique cracking behavior, including a crack width to below 100 µm.

Sealcoating: Is 50 Degrees Really Warm Enough?

Friday, April 13th, 2012

Most (if not all) sealcoat manufacturers recommend a minimum application temperature of 50 degrees. And I know what you are thinking; “is 50 degrees really warm enough?” Well, yes and no.

50 degrees should be the minimum temperature you BEGIN sealing at. And this is only acceptable when you have at least 3 hours of sunshine and the temperature will stay above the 50-degree mark during the application process. Otherwise, you risk complications.

Remember, 50 degrees is a MARGINAL starting point only. If you have any doubt about the weather or temperature before you begin sealcoating, be safe and do not begin the application process!

To ensure that your sealcoat project is performed correctly, contact an experienced asphalt company today – a company like PTG Enterprises.

Asphalt parking lot maintenance is important. But of all the precautions you can take to ensure your parking surface lasts for a long time, sealcoating is perhaps the most important. So do the right thing for your parking lot and have it sealcoated every 2-7 years, or as needed. This will protect your asphalt surface and greatly minimize the need for constant maintenance and repairs.

If you have any further questions about Sealcoating or have a Sealcoating Project that you need completed, then contact PTG Enterprises aka My Pavement Guy today by calling 410-636-8777 or click here today!

The Great Debate: Asphalt vs. Concrete

Friday, April 6th, 2012

Which is better, asphalt or concrete? That is the question that people have been asking for years upon years upon years. And to this day, we have no definitive answer.

Yet, while there is no all-encompassing answer, both asphalt and concrete have their advantages and disadvantages depending on the type of project being undertaken. So before you make a pavement decision, you need to ask yourself the following set of questions:

•      Which pavement better for my specific project?

•      Which pavement will be the most cost-effective? The American Concrete Pavement Association (ACPA) and NAPA encourage contractors to look at the long-term costs of maintenance and rehabilitation and not upfront costs.

•      Which pavement will last longer?

•      Which pavement will require the least amount of maintenance costs? 25% of roads in cities across the United States must be either rehabilitated or completely replaced in the next two years.

•      Do I want to fully replace, or rehabilitate?

“There are three main factors to consider: initial cost, time to first rehabilitation, and cost of total reconstruction or major rehabilitation at the 40- to 50-year mark,” said Dave Newcomb, P.E., PhD, vice president of research and technology with the National Asphalt Pavement Association (NAPA).

Benefits of Concrete

New construction: Concrete may be a good way to minimize future inconvenience when building new roads or expanding existing roads.

Around Underground Utilities: When separating sewer and drainage pipes (no more combined sewers), the public works department must dig out the roadway, which could present a good opportunity to go in and place longer-life pavements.

Benefits of Asphalt

Perpetual Asphalt: Asphalt also can be specified as a long-term solution. While some pavements must be completely removed and reconstructed, perpetual pavements can last indefinitely, with the only rehabilitation being milling of the surface followed by asphalt overlay. Perpetual pavement is designed to resist structural fatigue distress for at least 50 years.

Asphalt Overlay: An asphalt overlay, which can be placed on either an asphalt or concrete roadway, is fast and cost-effective to construct. The result provides a smooth, safe, durable, quiet surface for many years.

Still, there is no clear cut winner.

“If we get communities to base roadway design on total life of pavement and total capacity, concrete and asphalt are comparable in many ways,” said Scott Haislip, director of streets and roads with the ACPA.

Asphalt versus concrete

Martin O’Malley’s wants to apply the Sales Tax to Gasoline and Diesel

Thursday, March 29th, 2012

There are only a few weeks remaining in Maryland’s General Assembly. And many issues are still unresolved, including Maryland Governor Martin O’Malley’s proposal to add the state’s 6% sales tax to both gasoline and diesel.

  • The current motor fuel excise tax of 23 cents/gallon for gasoline and 24.25 cents/gallon for diesel would remain intact.
  • The 6% sales tax would be phased in at 2% per year over three years.
  • The sales tax would be calculated based on the six month average cost of the lowest grade of gasoline and then applied to both gas and diesel.
  • The tax would be calculated after subtracting the current federal and state excise taxes.

As you can imagine, the governor’s proposal has been met with a lot of opposition, especially from members of the Maryland Motor Truck Association (MMTA) and the rest of the transportation industry.

How do you feel about O’Malley’s proposal? We want to know what you think!

Other issues still being debated that concern the transportation industry include:

  • Require mandatory off-loading of vehicles carrying perishable products if they exceed the gross vehicle weight limit by more than 5,000 lbs.
  • Permit Baltimore City to install height detectors to electronically enforce time-of-day restrictions on prohibited truck routes.
  • Authorize the Maryland State Police to adopt certain sections of Parts 385 and 386 of the Federal Motor Carrier Safety Regulations, governing new entrant carriers and carriers declared as imminent hazards.
  • Tighten the procedures for public hearings and notice requirements before the MD Transportation Authority approves a toll increase.
  • Prevent transfers of monies out of the Transportation Trust Fund.
  • Eliminate an outdated certification requirement for drivers carrying controlled hazardous substances.
  • Expand the sales tax to dozens of services, including motor vehicle repair and maintenance.
  • Make the state’s cell phone ban a primary offense.

If you have any further questions about the Governor’s Tax Proposal, contact an experienced asphalt company today – a company like PTG Enterprises.
