STUDY OF BITUMINOUS SURFACE TREATMENTS IN VIRGINIA: ANALYSIS OF FACTORS THAT SIGNIFICANTLY INFLUENCE THE QUALITY OF BITUMINOUS SURFACE TREATMENTS

The purpose of this study was to define those variables which significantly influence the quality of surface treatments in Virginia and to determine the acceptable limits for them. Of the many variables included, air temperature, surface temperature, average vehicles daily, and age at the time of evaluation seem to most significantly affect the performance of a surface treatment. Three of these variables, air temperature, surface temperature, and AVD, are controllable and one, age, is not controllable. Based on the information obtained in this study it appears that the lower limit for air temperature should be 70 deg F and the upper limit for AVD should be approximately 400, assuming procedures for surface treatment work remain the same as encountered in this project. It was found that air and surface temperatures correlate well, and it is only necessary to control one. (Author)
