The effect of the amount of HVA adhesive on the structural properties of PAC-13 was analyzed
Due to the safety and comfort of driving PAC-13 in rainy days,China's expressways have been more and more widely applied in the construction.In order to study the influence of the amount of high viscosity agent HVA on the structural performance of PAC-13 drained asphalt mixture,four groups of target dosage were proposed by combining the empirical method and the experimental method.The PAC-13 asphalt mixture specimens with HVA high adhesive content of 6％,10％,14％and 18％voids of 21.7％were formed,and the structural properties of raw materials and PAC-13 were compared and analyzed.The test results show that the content of HVA is about 10％,and the three indexes of asphalt,dynamic viscosity,leakage,flight loss and TSR of mixture meet the requirements and are economical and reasonable.
