Asphalt Paving

Patching failed asphalt areas prior to sealcoating can be a low cost way to avoid the high cost of new asphalt. If new asphalt is required we have the equipment and experienced crew to be able to overlay the existing lot with new asphalt creating a stronger foundation.

The ongoing seperation of aggregreate particles from the pavement's surface. Unsightly stains that weaken the surface. A series of small blocks, resembling alligator skin or chicken wire, formed by interconnecting cracks. Bowl-shaped holes of various sizes. Aggregate in pavement has been smoothed resulting in slick unsafe surface.
Cause: Cause: Cause: Cause: Cause:
UV rays oxidize pavement's binder, cause aggregate to seperate from pavement. Oil dripping from vehicles, overfilling of fuel tanks. Stress results in pavement movement. Poor drainage, insufficient pavement thickness, negligence of crack sealing and sealcoating. Repeated traffic polishes aggregate.
Repair: Repair: Repair: Repair: Repair & Prevention:
Sealcoating Patching or application of special bonding primer prior to sealcoating Patching Full-depth asphalt repair Use of special bonding primer to gain adhesion, then sealcoating
Prevention: Prevention: Prevention: Prevention:
Application of sealer after new asphalt has cured. Sealcoat with gas and oil resistant sealer as quickly as possible after new asphalt has been layed. Proper pavement installation, timely crack filling, sealcoating. Proper construction, timely crack sealing, sealcoating.

Interconnected cracks that form a series of large irregular blocks, usually having sharp angles at the corners. Localized low areas that are limited in size, often indicated by standing water. Cracks spaced evenly apart and fairly parallel A fairly regular pattern of wave-like bumps. Surface crack in new surface overlay.
Cause: Cause: Cause: Cause: Cause:
Shrinkage of asphalt mix due to oxidation, with resulting loss of flexibility Traffic may be heavier than the pavement was designed for, or a localized subsurface drainage probled may exist. Weak or weathered joints between paving lanes, also extreme pavement temperature changes. Lack of stability in asphalt layer. Movement of pavement below the surface layer.

How does your pavement stand up?

10-20 EXCELLENT CONDITION

Your pavement is in good condition. The secret to protecting it from future deterioration is to sealcoat. Just like paint protects wood, sealer protects your pavement.

21-30 GOOD CONDITION

Usually, you'll find that pavement in this state is characterized by random cracks up to 1/2 inch wide and raveled aggregrate. The key to remedying these pavement problems is to professionally clean the cracks, removing any vegetation, and fill the cracks with an industrial grade crack filler. After the cracks are filled the lot should be covered with an asphalt overlay or a sealcoat to prevent further damage.

31-40 FAIR CONDITION

This pavement may contain random cracks, raveled aggregate, depressions, local alligator areas, pot holes and perhaps, upheaval. The first step in saving this paved area is to construct a full-depth asphalt repair where needed, taking care to resolve any problems with the subgrade. Following the repair of local depressions, cracks should be filled. Depressed areas should be restored to the proper cross-section by applying a leveling or wedge course, which is an asphalt layer of variable thickness. Finally, an asphalt overlay or sealcoat should be applied.

41-50 POOR CONDITION

If your pavement has numerour, severe problems, the most efficient way of dealing with it may be to repave. Before doing this, you'll want to make sure problem-causing conditions, such as poor drainage or inadequate underlying soil conditions, are corrected. Once the asphalt is laid, you should protect your pavement from needless deterioration by having it sealcoated. With proper maintenance, you'll find your new pavement to be a lasting addition and enhancment to your property investment.
