Evaluation of Temperature Effects on Bituminous Pavement Deflections in Virginia
Report No: 76-R50
Published in 1976
About the report:
Eight satellite projects with asphaltic layer thicknesses varying from 3.5 inches (88 mm) to 13.5 inches (338 mm) were tested for dynaflect deflections during the four seasons of 1974-75. The projects were located throughout Virginia. The evaluation of the deflection data showed the maximum deflection, the area of the deflected basin, and the spreadability and modulus of elasticity of the deflected basin to be functions of the log of the temperature. The asphaltic concrete thicknesses are divided into three groups of 2 to 4 inches (50 to 100 mm), 4 to 10 inches (100 to 250 mm), and 10 to 15 inches (250 to 375 mm) for a correlation of the mean pavement temperature with temperature adjustment factors. Correlation equations and graphs are developed.
