Paving an Asphalt Parking Lot

New Parking Lot Paving

Paving a parking lot in the Louisville, Ky and Southern Indiana area is more than just laying a top coat of asphalt. The preparation and the grading of the aggregate sub base is more important for a long lasting asphalt parking lot. The base must be set to properly run off water to prevent heaving of the asphalt during freezing and thawing. It also must be compacted so no soft spots remain in the sub base. These soft spots are what causes cracking and pot holes. The aggregate base below the asphalt sinks and the asphalt follows.

Striegel Paving takes the extra time and effort to ensure the integrity of the soil and the base layer of aggregate so you can decrease the amount of money you have to spend on asphalt repairs in the future.

During the construction of your parking lot, the first step is ensuring the soil is capable of holding the weight of vehicles over time. Removing soft areas of dirt down to clay and compacting large aggregate in its place creates a stable surface. After the large aggregate is compacted the smaller aggregate is compacted above the large. The smaller gravel will used as the base the asphalt will ride on.

Drainage for Asphalt Parking Lot

Every parking lot comes with its own set of challenges in terms of deferring water. Commercial parking lots require designed plans to catch water run off. These plans are put in place using catch basins and elevation changes. The sloped grade allows water to run off the top layer of asphalt and into the catch basins.

Water drainage is extremely important for a long lasting park lot. Water is the most detrimental force to an asphalt parking lot. It is the cause of all major damages to asphalt. Potholes, cracking and heaving are all caused by water not being properly redirected.
