Equivalent Stiffness Modulus of Polyester Fiber Reinforced Asphalt Concrete
The equations established for fiber reinforced composites by Zhao and Tandon using the theory of micromechanics are used to discuss effective stiffness moduli of fiber reinforced asphalt concrete under low temperature. The results of these equations are compared with experimental data from splitting test under several temperature levels within , and the differences are analyzed in detail. It is found that the error is sensitive to temperature and fiber content. According to the result of error analysis, new modified equivalent modulus equations are defined, in which the changes of temperature is taken into account, and the comparison between results derived from the new equations and test data suggests a nice consistency when fiber content is less than 0.2%.
