CONCEPTS FOR DEVELOPING A NONDESTRUCTIVE BASED ASPHALT CONCRETE OVERLAY THICKNESS DESIGN PROCEDURE

Preliminary flexible pavement asphalt concrete (AC) overlay thickness design concepts utilizing NDT (nondestructive testing) data are presented. The Illinois DOT Road Rater (8 kip peak to peak lading, 12 inch diameter plate) was the primary NDT device. Conventional pavements (surface treatment-granular base; AC surface plus granular base), full depth asphalt concrete (AC surface plus AC base), and stabilized base (with or without AC surface) pavements are considered. Field evaluation, NDT testing, NDT data interpretation, and overlay thickness determination procedures are proposed. The overlay design concepts presented are primarily based on the data and findings from several previous University of Illinois and Illinois DOT research studies and reports. The procedure is directed toward the determination of the appropriate AC overlay thickness. It does not provide guidance or direction regarding the need for the AC overlay. (FHWA)
