Tar / Asphalt Tips

 

 

 

As soon as freshly laid hot asphalt begins to cool, the aging process begins.  From that moment on, asphalt is broken down by oil, gas, sun oxidation, salt, water penetration, and cold weather.  Refer to the following tips when making decisions regarding preventative maintenance.

 

Carefully inspect your pavement on a regular basis for cracks, fading pavement markings, and other signs of failure or liability issues

 

Sealcoating a parking lot helps to slow pavement deterioration; for maximum benefit, asphalt should be sealed every 24-36 months

 

Sealcoating should only be performed under the proper weather conditions (50°F during sealer application and for 8 hours afterward)

 

Traffic should be kept off a newly sealed surface for 24 hours to allow for drying (curing) time

 

Proper attention to cracks will prevent problems from spreading and double the life of pavement

 

Singular cracks that are between ¼-inch wide and 1-inch are good candidates for cracksealing

 

Crack widening or “routing” is strongly suggested in truck areas, but not in cracks that have already been sealed

 

Fixing “birdbaths” as soon as they appear will lessen the chance of water seeping through to the base and becoming a pothole

 

Catch basin installation can be a possible solution for improper drainage on a parking lot

 

All pre-existing problems such as cracking, low spots, poor drainage, and base or sub-base damage should be resolved before resurfacing pavement

 

Concrete is especially durable when it is mixed properly and caution is taken during the curing process

Concrete needs at least 4-7 days to cure, during which time the surface should be constantly wet

Lot marking using a “straight-in” design (at 90°) allows for the most stalls and accommodates two-way traffic flow
