Water Drainage
The biggest culprit to pavement failure is water. Standing water along the sides of your pavement allows moisture to soak beneath and saturate your gravel base leaving your pavement vulnerable to heavier vehicles and frost heaves. Get the water away and your pavement will stay! We evaluate pavement projects for the following water drainage factors:
Evaluate Current surface drainage and sources of water
Examine pavement slope and where the water will settle
Identify potential water drainage issues and plan redirect
Gravel Base
The asphalt we put down is only as strong as the supporting gravel base it is resting on. Asphalt pavement stacked on a solid, compacted base should leave a 6″ to 12″ gravel shoulder on each side of the finished asphalt pavement. Here are some additional points on establishing a stable asphalt gravel base.
An adequate foundation includes both a solid subgrade and aggregate base
The Size or thickness of the subgrade and aggregate base rock is critical
The subgrade must be dry and properly stabilized prior to paving
Pavement Edging
The main purpose of asphalt driveway and parking lot edging is to form a barrier or border between your pavement and landscaping. It also helps to keep loose gravel contained and minimizes erosion on slopes. Included below is an outline of our pavement edging process
Straight edging with a sloped rough outer edge will allow topsoil to cling and prevent water from eroding the soil.
After asphalt is rolled and cooled, topsoil is placed along all exposed edges and seeded.
Once grass is established, your asphalt edges will now be supported from the sides.
Simply put, asphalt pavements fail due to poor drainage, lack of gravel or incorrect edging. So why not let the experts at Asphalt Maintenance and Paving Inc design your asphalt pavement to last you for years and years.
