Minimum Asphalt Thickness For Roads

Pavement Thickness Design Institute for Transportation

In an effort to show the effect of varying traffic loads and subgrade treatments on pavement thickness, this section provides comparison tables showing the Road Test data fits the AASHTO Design Equations. The lower the overall deviation, the better the equations model the data. The following ranges are recommended. • Rigid AASHTO Pavement Thickness Design Guide CECALC

How Thick Should Your Asphalt Be? Stripe A Lot

When asphalt is installed properly the thickness of the material and its natural flexibility spreads out the weight of the load, which is ultimately supported by the base layer underneath. But if the asphalt is too thin the weight isn’t distributed and compresses the material right underneath the tire, causing it to pull away from the
