Asphalt Concrete Section

Materials

About this detail

A standard asphalt concrete pavement section features a three-inch asphalt pavement wearing course resting upon a four-inch Class 2 aggregate base. The aggregate base requires compaction to at least ninety-five percent relative compaction per ASTM D 1557 geotechnical recommendations. Below the base lies a twelve-inch minimum scarified, moisture-conditioned, and compacted subgrade layer. The subgrade preparation excludes required over-excavation, which must be verified per the geotechnical report.
