Optimization of Reclaiming Agent Dosage and Gradation of In-site Hot Recycling Mixture for Asphalt Pavement
In order to improve the recycled asphalt mixture gradation,the accuracy of the new asphalt mixture dosage,guarantee the comprehensive performance of recycled asphalt mixture,from the old asphalt mixture,asphalt performance,the old mixture grading,the skeleton dense design method designed the recycled asphalt mixture gradation,test the amount of new asphalt mixture,finally carried out the recycled asphalt mixture at high temperature,low temperature,water stability test.Through the optimization design of in-site hot recycling asphalt mixture,confirm the synthesis of recycled asphalt mixture grading using skeleton compact and low ratio of mix-ture,regeneration agent dosage for 4%of the quality of the old asphalt mixture,the mixture of high temperature,low temperature,water stability and hot asphalt mixture performance,finally put forward the construction process intermediate with variation should be timely variation strategy.
