Experimental Study on Road Performance of Grouting Semi-flexible Pavement Materials
A high-quality cement mortar grouting material has been developed,the asphalt mixture with large pore matrix which meets the technical requirements of the regulation is designed based on field aggregate performance,of which the optimum ratio is 4.0％through leakage loss test and flight loss test.The semi-flexible pavement material with a filling rate of 86.5％was prepared from these materials.The road performance of grouting semi-flexible pavement materials was analyzed and evaluated through Marshall stability test,immersion Marshall test,splitting and freeze-thaw splitting test,rutting test,low temperature bending test and normal temperature bending test.The result shows that the grouting material can obviously improve the mechanical properties,Marshall stability,dynamic stability and anti-spalling ability of the base asphalt mixture,that grouting semi-flexible pavement material has good water stability and high temperature performance,and Low temperature performance is not very good,and that grouting semi-flexible pavement material is suitable for hot and humid areas in south.
