• Abstract:
  A structural evaluation was performed on 25 base recycling projects in the Bryan District. The recycled layers were stabilized with cement or lime, and each was 250 mm thick. On the higher volume roadways, an unstabilized flexible base was placed over the stabilized layer, followed by a two-course surface treatment (2 CST). On the other pavements the 2 CST was placed directly on the stabilized layer. Testing involved the use of the Dynaflect, falling weight deflectometer, dynamic cone penetrometer, and ground penetrating radar. A correlation was generated between the back calculated layer moduli and the percentage of stabilizer used. Tentative moduli values, to be used in future thickness designs, were also proposed.
