Dr. Ken Maser Presented on Network-Level Pavement Structure Evaluation at the World Conference on Pavement and Asset Management (WCPAM)

Dr. Ken Maser presented the results of a network-level pavement substructure evaluation completed in Idaho. The project focused on a network of 700 miles of roadways covering a wide range of geographic and pavement structure conditions. The roadways were continuously surveyed with a Traffic Speed Deflectometer (TSD) and with Ground Penetrating Radar (GPR). The TSD data was analyzed along with the associated GPR layer thickness data to determine subgrade modulus, pavement modulus, structural number, and remaining life.
