About this detail

This heavy duty pavement section details a layered roadway assembly starting with a 3 1/2 inch asphaltic concrete wearing surface. Below the asphalt sits a 10 inch untreated base course compacted per specifications. The subgrade or fill layer is properly prepared and compacted in accordance with the geotechnical report and specifications, resting directly on undisturbed earth. Accompanying asphalt notes specify requirements for subgrade preparation, structural fill compaction limits per AASHTO T-180 methods, lift thicknesses, and the removal of surface vegetation.
