Research on the Road Performance of High Viscosity Composite Modified Basalt Fiber Drainage Asphalt Mixture
摘要
Abstract
In order to improve the poor bearing capacity of large pore drainage asphalt pavement and the low bonding capacity between asphalt and mineral materials,and extend its service life,we used AR-HVA high viscosity agent and basalt fiber to make composite modification of SBS polymer modified drainage asphalt mixture,and carried out high temperature rutting resistance,low temperature cracking resistance,water stability and water seepage performance tests to evaluate the improvement effect of the addition of AR-HVA high viscosity agent on the related properties of drainage asphalt mixture.The reasonable dosage range of AR-HVA high viscosity agent was determined.The mineral grade and the optimum oil-stone ratio of PA-16 drainage asphalt mixture were determined by the mix ratio design.The test results show that with the increase of the content of AR-HVA high viscosity agent,the high and low temperature performance and water stability of the asphalt mixture are gradually increased,and the water permeability performance does not change significantly.From the comprehensive consideration of economy and high and low temperature performance,we determined that the recommended dosage of AR-HVA high viscosity agent was 8%.From the comprehensive consideration of economy and water stability performance,we determined that the recommended dosage range of AR-HVA high viscosity agent was 6%~8%.关键词
