PREDICTING REDUCTIONS IN SERVICE LIFE OF SURFACE-TREATED PAVEMENTS UNDER OIL FIELD TRAFFIC.

Pavement distress and performance equations for thin pavements are developed that relate pavement damage to traffic loading. These equations, developed by regression analysis, use pavement condition data collected during a seven-year period on thin pavements in Texas. Initial results demonstrate that these regression equations are better predictors of long-term performance than the AASHTO equation. A case study is presented to outline how these predictions were used to calculate reductions in pavement life and increases in life-cycle costs associated with the oil field development. This study predicted that the oil field development reduced the remaining life of a typical thin pavement from 46 to 16 months and increased the rehabilitation costs tenfold from 0. 50 to more than 5. 00/yd.
