基于疲劳性能的透水沥青混合料配合比研究
Research on pervious asphalt mixture ratio based on fatigue performance
摘要
Abstract
The article aims to conduct research on the mix design of permeable asphalt pavement,and develop permeable asphalt structures that are suitable for China's road conditions and have excellent performance.This study investigates the effects of porosity,asphalt type,and asphalt dosage on the fatigue performance of OGFC mixtures.Based on this,analyze the trend of porosity with key sieve pass rate,correct the OGFC grading range,determine a new mix design method,and verify the performance of the mixture.The results indicate that porosity has the greatest impact on fatigue performance,followed by asphalt type,and finally asphalt dosage;The relationship between the porosity and the pass rate of the 2.36 mm sieve is the closest,optimized and adjusted to 19%～27%,and the pass rate and porosity follow a linear regression relationship;The optimum asphalt-to-aggregate ratio was increased to 6%based on the new gradation range,and the mix was verified to meet the specification for both high and low temperature performance and water stability.关键词
