Composition Design and Noise Reduction Characteristics of HVA/SBR/TPU Modified Porous Asphalt Pavement
摘要
Abstract
To reduce traffic noise pollution,a high-viscosity asphalt modifier(HVA)/styrene-butadiene rubber(SBR)/thermoplastic polyurethane(TPU)composite modified porous asphalt mixture was developed.The response surface methodology was employed to determine the optimal blending ratio of the HVA/SBR/TPU composite modifier.The optimum asphalt content of the porous asphalt mixture was then determined through draindown tests,Cantabro abrasion tests,and volumetric void content measurements.Furthermore,the noise reduction performance of the mixture was analyzed using the finite element method.The results show that the optimal combined dosage of the composite modifier is 7%HVA,6%SBR,and 1%TPU.For the porous asphalt pave-ment with a target void content of 21%,the optimum asphalt content is 4.7%.Compared with the conventional AC-13 pavement,the proposed HVA/SBR/TPU modified porous asphalt pavement exhibits a noise reduction of 3.5 dB,demonstrating a significant noise-reducing effect.关键词
