FOLLOW-UP STUDY FOR THE CALIFORNIA RESILIENCE DESIGN METHOD

California's research efforts to develop and implement a structural design method for flexible pavement sections overlying untreated bases and resilient basement soils are described. This design method involves testing soils for resilience properties and predicting pavement deflections for proposed structural sections. Predicted deflections are compared to previously developed tolerable deflection levels for varying asphalt concrete thicknesses and traffic indexes. When predicted deflection values exceed tolerable deflections, an additional increment of subbase or base material is designed to reduce predicted deflection values to tolerable levels. The resilience test equipment used to determine potentially resilient soils is described. The mobile equipment, Deflectometer and Dynaflect, used to measure deflections on the as built pavements is also described.
