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

Wide Lines Lead to Safer Highways

Friday, March 23rd, 2012

A study “An Evaluation of the Effectiveness of Wider Edge Line Pavement Markings” – conducted by Texas A&M University’s Transportation Institute (TTI) found that wider paint lines on roadway shoulders (edge lines) reduce crashes and fatalities. The study analyzed Federal Highway Administration data from Kansas, Michigan and Illinois. The evidence all supported the adoption of wider edge lines.

Study Findings

•      Wider edge lines have been shown to reduce total crashes 15 to 30 percent

•      Wider edge lines have been shown to reduce fatal plus injury crashes 15 to 38 percent

•      The benefit-cost ratio for wider edge lines is $33 to $55 for each $1 spent

This provides highway officials with a very cost-effective, statistically sound way to improve safety without expensive and inconvenient construction.

“With the ultimate goal being highway safety, transportation agencies across the U.S. now have strong data to support the undertaking of a relatively low-cost measure to improve highway safety and reduce fatalities,” said Kevin Goforth, president of the American Glass Bead Manufacturers’ Association, who sponsored the study.

Many states have already made the switch to wider edge lines, opting for six inches instead of four inches. But until this study, those changes were made without sound empirical findings to support the decision.

If you have any further questions about this study, contact an experienced asphalt company today – a company like PTG Enterprises.

Study: Wider Line Markings Make Highways Safer

New ADA Standards Make Pavement Contractors Indispensable

Friday, March 16th, 2012

Last week, we told you about Americans with Disabilities Act, Title III – the new ADA standards that guarantee persons with disabilities are provided accommodations and access equal to, or similar to, the general public into commercial facilities and areas of public accommodation. And last week, we told you how these new standards would affect business owners across the nation. Well, what about pavement contractors?

All signs point to the ADA standards as a bonus for the pavement maintenance industry. When business owners are faced with the challenge of complying with these new standards (a full list can be found at http://www.ada.gov/), whom do you think they will call?

Pavement Contractors!

These new ADA standards create a network of accessibility that leads from one requirement to the next with each stage having specific requirements that must be met. And like any government regulation, the new ADA Standards are complex and can, at times, be difficult to decipher. But this just means that pavement contractors will become increasingly indispensable to business owners everywhere as the nation strives to comply with Americans with Disabilities Act, Title III.

If you have any further questions about compliabnce with these new ADA standards, contact an experienced asphalt company today – a company like PTG Enterprises. The asphalt experts here have managed hundreds of pavement projects and have the experience you need.

How ADA Updates Can Make You Indispensible To Your Customer

Americans with Disabilities Act, Title III

Friday, March 9th, 2012

Next Thursday, March 15, 2012, compliance with Americans with Disabilities Act, Title III becomes mandatory. Title III guarantees persons with disabilities are provided accommodations and access equal to, or similar to, the general public into commercial facilities and areas of public accommodation.

The 2010 updates are enforceable under civil rights law. This means that a person is able to file lawsuit if he/she has “reasonable grounds” for believing that discrimination is about to occur, rather than filing a grievance after the fact. A civil law suit can be filed with penalties of up to $100,000 imposed per offense.

To help facilitate the transition process, the U.S. Department of Justice (DOJ) is allowing a one-year “grace period” for businesses to prepare for the changes.

2010 ADA Guidelines

  1. Facilities that provide goods or services directly to the public: These facilities will be required to remove architectural barriers in existing buildings, and must make sure that newly built or altered facilities are constructed to be accessible. 
  2. Facilities that do not provide goods/services directly to the public: These facilities are only subject to new construction and alteration requirements.
  3. Small businesses with very limited parking (four or fewer spaces): These businesses must have one accessible parking space; though no new signage is required.
  4. Medium-Large Businesses: Non-van accessible parking stalls need to be 8’ wide with a 60″ aisle. For van-accessible parking, the van parking stall should be 11’, with a 60″ access isle. Plus, disabled parking signs are required on all accessible parking spaces, and should be easily visible, a minimum of 60″ off the ground.

However, specific ADA regulations will vary depending on location.

Perpetual Asphalt: Asphalt for Performance

Wednesday, February 29th, 2012

With perpetual pavements, asphalt pavements last longer. This means that your investment will last longer. And who doesn’t like a good investment?

Perpetual asphalt is constructed so that distress occurs on the top layer only, protecting the rest of the pavement. This means that the only rehabilitation required is the removal of the surface and resurfacing with an asphalt overlay. And with current pavement technologies, this only has to be done every 15 to 20 years.

Benefits of Perpetual Asphalt

Durability: Perpetual asphalt has an extremely long lifespan. These pavements require minimal maintenance and no full-depth reconstruction.

Rubblization: The concrete pavement is left in place, rubblized (fractured), and used as the base for a new Perpetual Pavement. This is beneficial for several reasons, including:

•      It is environmentally friendly

•      It saves money

•      It is incredibly fast to construct and rehabilitate

•      It cuts down on road repair time

Safety: Smooth asphalt roads give vehicle tires superior contact with the road.

Noise Reduction: Noise reductions of 3 to 10 dB(a) are common. Reducing noise by 3 dB(a) is about the same as doubling the distance from the road to the listener, or reducing traffic volume by 50 percent.

Fuel Efficiency: Studies at a pavement test track in Nevada have shown that driving on smoother surfaces can reduce fuel consumption by 4.5 percent.

Perpetual Pavement is the ultimate in sustainable design and construction.

Performance Means Sustainability

Porous Asphalt: Improving Stormwater Management

Friday, February 24th, 2012

We have a new, powerful tool to help improve stormwater management and water quality: Porous Asphalt.

In nature, rainwater is absorbed by soil, filters through it, and eventually seeps into streams, ponds, lakes, and underground aquifers. In urban areas, rainwater falls directly  on cement and asphalt pavements and has nowhere to filter out harmful contaminants. As a result, those contaminants are washed into waterways without undergoing the filtration that nature intended.

This is where porous asphalt can help!

Porous asphalt has an open-graded (porous) surface over an underlying stone recharge bed, allowing rainwater to drain through the asphalt, into the stone, and then the soil. If contaminants were on the surface at the time of the storm, they are swept along with the rainfall through the stone bed. From there they infiltrate into the sub-base so that they are subjected to the natural processes that cleanse water.

Benefits of Porous Asphalt

•      Conserve water

•      Allow for better use of land

•      Reduce runoff

•      Promote infiltration

•      Clean stormwater

•      Replenish aquifers

•      Protect streams, ponds, and other waterways

Porous asphalt pavements are being used successfully throughout the United States, in every type of climate and geography. They are recognized by the Environmental Protection Agency as a best management practice for stormwater management.

Asphalt for Better Water Quality

Asphalt and the Environment

Thursday, February 16th, 2012

Believe it or not, asphalt is actually not bad for the environment. Don’t believe me, then check out the facts:

  • Between 1960 and 1999, while production of asphalt pavement material increased by 250 percent, total emissions from our operations decreased by 97%.
  • Asphalt is an environmentally sustainable pavement.
  • Once constructed, asphalt pavements have minimal impact on the environment. Studies show that asphalt pavements and stockpiles of reclaimed asphalt pavement do not leach.
  • Asphalt and the processes used to produce asphalt are green.
  • Asphalt pavements require about 20 percent less energy to produce and construct than other pavements.
  • Asphalt pavement is America’s most recycled product, with about 70 million tons of asphalt pavement material being reclaimed. And more than 99% of that total is reused or recycled. In 2010 alone, asphalt recycling conserved over 20.5 million barrels of asphalt binder.
  • Porous asphalt pavements offer a tool for storm water management with both environmental and economic benefits.
  • Warm-mix asphalt reduces fuel consumption, cuts greenhouse gas emissions, and enhances the quality of pavement.
  • Porous asphalt pavements have been shown to lower nighttime surface temperatures as compared to impervious pavements.
  • Asphalt pavements are faster to construct and rehabilitate.

Asphalt, The Sustainable Pavement

An Overview of the Different Types of Asphalt

Friday, February 10th, 2012

Asphalt is the most versatile pavement material, with mixes designed to handle any size load (from passenger cars to heavy trucks), absorb noise, reduce splash and spray during rainstorms, and even to help treat rainwater. The different types of asphalt pavement include:

Warm-Mix Asphalt: This is the generic name of the technology that allows producers of hot-mix asphalt to lower the temperatures at which the material is mixed and placed on the road. This afford asphalt contractors many benefits, including:

•      Increasing safety for asphalt workers

•      Cutting fuel consumption

•      Decreasing the production of greenhouse gases

•      Better compaction of pavements

•      Extending the paving season

•      And the potential to be able to recycle at higher rates

Quiet Pavement: Today’s busy world is filled with more noise than one typically cares to deal with. But quiet pavement actually reduces the noise experienced both inside and outside homes and businesses. Resurfacing a noisy road with stone-matrix asphalt (SMA) or open-graded friction course (OGFC) mix can reduce noise by 3 to 5 dB(A) or more (the same as doubling the distance between you and the noise source).

Porous Asphalt: These pavement surfaces allow rainwater to drain through the asphalt into a stone recharge bed and then into the soil, eliminating potentially harmful standing water.

Perpetual Pavement: This advanced, multi-layer paving design process (along with routine asphalt maintenance) extends the useful life of a roadway.

Whether on the road, in a parking lot, or at an airport, asphalt pavements add up to the best value for your pavement needs, with the lowest life cycle cost and the highest residual value.

The Interesting History of Asphalt Pavement

Friday, February 3rd, 2012

It doesn’t matter is you call it asphalt pavement, blacktop, tarmac, macadam, plant mix, asphalt concrete, bituminous concrete, or just asphalt, today, it is everywhere! Asphalt is used in everything from shingles and sidewalks to driveways and, of course, roads (and more). But where did asphalt come from?

Asphalt Timeline

  • Asphalt occurs naturally in asphalt lakes and in rock asphalt and the first recorded use of this natural asphalt was in 625 B.C. when the Babylonians used the material to build their roads.
  • Even the ancient Greeks and Romans used asphalt. In fact, the word asphalt comes from the Greek word “asphaltos”, meaning “secure.”  The Romans, who used asphalt to  seal their baths, reservoirs, and aqueducts, later changed the word to “asphaltus.”
  • In 1595 Sir Walter Raleigh wrote about using natural asphalt to re-caulk his ships.
  • Still, hundreds of years passed before asphalt was widely used as a building material.
  • In the mid 1800’s John Loudon McAdam used broken stone and hot tar to bond the stones together.
  • In the late 1860s, “asphalt” came to America! The first bituminous mixtures were used for sidewalks, crosswalks, and roads.
  • In 1852, French Highways utilized natural asphalt pavement.
  • Then in 1870, Edmund J. DeSmedt laid the first true asphalt pavement in America, a sand mix in front of the City Hall in Newark, New Jersey.

Since that time, asphalt has taken off. Today, over 750 million tons of asphalt is poured and rolled every year…JUST in the USA.
