Baltimore, Maryland’s famous Inner Harbor almost never existed. In the early 1960s, a proposed road project threatened what would become the Inner Harbor. Luckily, residents of Federal Hill joined forces with other Baltimoreans and defeated the highway project. This proved to be the right move not only for Federal Hill, but also Baltimore.
The completion of Rouse’s Inner Harbor in the early 1980s brought acclaim to Baltimore and quickened the pace of revitalization in nearby Federal Hill. Then in 1994, Federal Hill park underwent a facelift. Residents wanted a better pavement than the existing gravel. They needed a pavement that would accommodate both carriages and heavy commercial trucks.
The Solution: Concrete pavers!
Reminiscent of the cobblestones used in many of Baltimore’s streets, concrete pavers provided an aesthetically pleasing, incredibly durable, and cost effective solution for Federal Hill. Since the use of concrete pavers in the park, they have spread to several blocks of sidewalks within the neighborhood.
The pavers were placed over 1 in. (25 mm) of bedding sand on 12 in. (300 mm) of compacted aggregate base.

Asphalt is used everywhere, from roads and parking lots to runways and more. And why not? Asphalt boasts several benefits, including:
- Asphalt has excellent waterproofing properties.
- Asphalt has excellent binding (or cementing) properties to hold the aggregates in the pavement.
- Asphalt pavement has a long life & resurfacing is quick.
- Asphalt is America’s most recycled material.
- Asphalt is the most sustainable and environmentally-friendly pavement on the market.
- And more!
Still, asphalt has a few major deficiencies as well. Asphalt has very poor resistance to weathering and is easily attacked by chemicals, gasoline, oils, and deicing salts. All of these elements work together to break down the asphalt, degrading the asphaltic oils from the surface as chemicals dissolve them away. And with the loss of asphalt cement, the aggregates in the top layer begin unraveling and develop the first sign of pavement deterioration; the appearance of minor surface cracks.
Over time, cracking will become more prevalent. And if not repaired, these cracks will allow water to penetrate sub-base and base layers, causing them to lose their ability to effectively bear traffic loads. Eventually, this will cause the asphalt pavement to fail.
To prevent further erosion of your asphalt pavement, or to fix a problem so it does not get any worse before winter, call PTG Enterprises for a property evaluation. You can expect a fair proposal, professionalism and quality work. A good contractor is hard to find!

Asphalt pavement is the preferred material for most state and federal road projects for a few very good reasons. Most notably, asphalt is known for its durability, strength, resilience, and longevity. Still, even the toughest asphalt road or parking lot undergoes a lot of wear and tear, eventually deteriorating to the point of no return.
Over time the materials that make up asphalt begin to break down, affected by elements such as rain, sunlight and chemicals. Asphalt binder loses its natural resistance to water, allowing liquids to penetrate the surface and deteriorate the pavement.
Asphalt Deterioration and its Causes
- Cracking: There are numerous different types of cracks, from alligator cracks and edge cracks to longitudinal cracks, block cracks, and more. When it comes to asphalt pavement maintenance and dealing with cracks, you have two basic options: crack sealing and crack filling.
- Distortion: Caused by improper pavement construction and the deterioration of the underlying base, asphalt distortion includes : channels or ruts, corrugations and shoving, grade depressions, upheaval and utility cut depressions.
- Disintegration: Asphalt disintegration includes potholes, raveling, and gas and oil spillage.
Asphalt must also be properly maintained and protected to maximize its lifespan.
Sealcoating and PTG Enterprises
Sealcoating is a crucial process in the preventative maintenance of any parking surface. The asphalt experts here have managed hundreds of Maryland, DC, and Virginia pavement projects and have the experience you need.

When it comes to asphalt pavement maintenance and dealing with cracks, you have two basic options: crack sealing and crack filling. But which is best? Well, that all depends on the situation. So before we get into crack filling vs. crack sealing, we must first address the different types of asphalt cracks.
Types of Asphalt Cracks
- Transverse Cracks: These cracks are caused by reflective cracks from an underlying layer, daily temperature cycles, and poor construction due to improper operation of the paver.
- Longitudinal Cracks: These are cracks that are parallel to the pavements centerline or laydown direction and are the result of pavement fatigue, reflective cracking, and/or poor joint construction.
- Edge Cracks: These cracks appear along the inside edge of a pavement surface within one or two feet and are commonly caused by poor drainage conditions and lack of support at the pavement edge.
- Seam Cracks: These cracks occur along the paving joints and are typically caused by improper hot mix paving procedures.
- Block Cracks: These cracks look like large interconnected rectangles, hence their name. Block cracking is generally caused by shrinkage of the asphalt pavement due to an inability of asphalt binder to expand and contract with temperature cycles.
- Reflective Cracks: These cracks appear when the surface material cannot adjust to the changes in the movement of the sub-surface courses.
- Alligator Cracks: Alligator cracking is a load associated structural failure due to weakness in the surface, base or sub grade; a surface or base that is too thin; poor drainage or the combination of all three.
When deciding whether crack filling or crack sealing is best, your asphalt contractor will take the expected movement of the cracks in the pavement into carefully consideration.
- Crack Filling: Generally, crack filling will be used for non-working cracks with moderate to no edge deterioration.
- Crack Sealing: Generally, crack sealing is used for cracks with limited edge deterioration
Experienced personnel – like the ones found at PTG Enterprises – can usually identify the crack type; working or non-working and take the appropriate action.

Over time, even professionally installed asphalt undergoes a tremendous wear and tear, causing it to crack and fail. Asphalt maintenance refers to the methods and techniques used to prolong the useful life of asphalt pavement.
Types of Asphalt Maintenance
- Asphalt Patching: his is where the pavement is completely removed in the troubled area and replaced. These areas are usually suffering from severe distress and / or sub-base failure.
- 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.
- Asphalt Overlay: An overlay is when a new and additional layer of asphalt is installed over what is already there.
- Asphalt Sealcoating: Sealcoating is a preventative maintenance 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).
If you notice your parking lot or any asphalt pavement displaying signs of deterioration, it is probably time to call an asphalt contractor, like PTG Enterprises, to help prevent further damage. Do not put this off and let small cracks become major problems.

You use asphalt every day. But have you ever stopped and wondered to yourself, “Hey, how is asphalt made?” If so, you are not alone. Despite being such an integral part of everyday life, few people know how asphalt is made.
So, without further ado, the process for making asphalt!
- Predose: A belt weigher is used to weigh the aggregate components of asphalt pavement. A belt weigher is used so that the materials can simultaneously be weighed and taken to the next step in the process.
- Drying: The asphalt components are dried in a rotary drying drum at roughly 300 degrees.
- Reweighing: Since drying can alter the weight of the aggregate, it has to be reweighed after drying.
- Storage: The dried components are then sifted and store in silos.
- Mixer: After being transferred to the mixer, binding element, or liquid asphalt is added to the aggregate. Both aggregate and binder are mixed thoroughly to form the paving material.
- Storage Round 2: After mixing, the asphalt is stored in a heated silo. If the asphalt mix cools it cannot be compacted.
- Application: The asphalt is transported by dump trucks to the job site for application.
Hopefully now you know a little bit more about asphalt than you did before!
