Study on the Performance of High Viscous Modified Basalt Fiber Open Graded Asphalt Mixture
摘要
Abstract
In order to improve the road performance of open-graded asphalt pavement,HVA-H high viscosity agent and basalt mineral fiber were selected for composite modification of OGFC-13 asphalt mixture.Introducing two types of high viscosity agents,HVA type and SEBS type,as a comparative evaluation of the improvement effect of HVA-H high viscosity agent on the performance of SBS modified asphalt and OGFC-13 asphalt mixture.By mix ratio design,We confirmed the best oil-stone ration of mixture when the content of HVA-H is 8％,HVA is 8％,SEBS is 8％,basalt fiber is 0.4％.By road performance test of asphalt mixture,we evaluated the influence of three kinds high adhesive on OGFC-13.The results showed that HVA-H high adhesive was the best to improve high and low temperature properties of asphalt HVA-H modified asphalt has the strongest bonding ability for mineral materials.The effect of HVA-H high adhesive on the high temperature rutting resistance,low temperature cracking resistance and water damage resistance of OGFC-13 asphalt mixture is significantly better than HVA and SEBS.关键词
