Research Of Performance And Application For Different Fiber Asphalt Mixture

There is a development tendency which presents high speed,heavy loading or traffic volume,and traffic channeling is increasingly apparent.Therefore,each aspect of asphalt pavement will be increasingly strict.In order to meet these requirements of asphalt pavement,there is a method that can blend fiber Additive with asphalt mixture,thereby,fiber Additive can act as reinforced materials,which can improve the integral physical and mechanical properties.It was proved that fiber can achieve that obviously improve asphalt pavement performance after mixed with fiber stabilizer.And then,the effect of improving asphalt pavement is prominent,so,in the area of road material,fiber stabilizer material exists a great researching value.Since the fiber material applied in asphalt pavement,fiber asphalt mixture presents a better pavement performance and simple construction properties.However,reviewing related research achievement at home and abroad,it exists some aspects needing researching deeply: there is no correlation research and specific evaluation method for asphalt mixture modified with different fiber Additive.There is no impact analysis of asphalt mixture based on different type,properties and amount of fiber Additive.Moreover,in these existing related researches,there is no technical and economic analysis based on pavement paved by fiber modified asphalt mixture.Correlation research between fiber properties and its effect in asphalt mixture,Special mechanism analysis against reinforcing effect after blended fiber stabilizer in asphalt mixture.Against fiber modified asphalt paste,trying to select suitable testing method in order to evaluate its performance.A series of pavement performance researches will be done,therefore,the related amount of different type and properties fiber will be confirmed.The performance impaction of asphalt mixture caused by different type and properties fiber.According to paving testing section,verified above research achievements,and related economic and technical analysis will be done.
