The idea is to place the PlasticRoad directly on a surface of sand. This removes the need for a foundation. Additionally, it saves two to three layers of asphalt that no longer need to be produced. First calculations show that a road made out of PlasticRoad elements requires 85% less transport than a traditional road.
To chipseal a road, a construction crew spreads a thin layer of heated asphalt liquid on the road, followed by a thin layer of chips, or stones. A steamroller compacts the layer, and crews sweep away excess stones. This method extends the life of a road and waterproofs the underlying foundation.
The thickness of pavements depends on a number of variables, but from experience it has been found that the following factors affect the performance of pavements to a great extent. Traffic Factors, Soil Factors, Environmental Factors, Stress Distribution Factors.. Traffic is the most important factor in the pavement design. The key factors include contact pressure
