Thin Asphalt Overlays in Division VI
Field Division VI has typically applied 'chip seals' to distressed low traffic roadways. Chip seals, however, have little effect on problems such as cracking, corrugating, and rutting. One or more of these problems existed at each of the seven sites selected for the application of thin asphalt overlays in lieu of chip seals. Four similar roadway compositions were represented. Each was overlaid with 0.5 to 0.75 inches (13 mm to 19 mm) of Type D asphalt concrete. Field tests included traffic data collection, flexible pavement condition surveys, and rut measurements, as well skid, ridemeter, and Benekelman Beam deflection tests. Construction consisted of three steps: (1) placing a tack coat or fabric membrane on the old surface, (2) laying down a thin lift of Type D asphalt, and (3) compaction.
