  • Abstract:
    The objectives of this project are to determine the strength characteristics of soil cement bases that were constructed under stabilized procedures (DOTD TR 432M/432-99) and the cement treated design philosophy. This was accomplished by using the Falling Weight Deflectometer (FWD) to obtain resilient modulus (Mr), the Dynamic Deflection Determination System (Dynaflect) to obtain structural number (SN), unconfined compression testing (ASTM D 1633), and durability testing (AASHTO T-135). Additionally, the testing conducted at ALF yields the total lane passes and equivalent single axle loads at failure. The results of these tests were 3 compared with established design values or standards of practice by DOTD, AASHTO, ASTM, and FHWA. If a cement treated design base course material meets the durability, resilient modulus, and layer structural number criteria, the base course should perform favorably for its projected design life and can be used as design option for soil cement base courses.
