Application of Slurry Sealing Layer Construction Technology in Highway Pavement Maintenance
In order to study the application effect of slurry seal technology in highway pavement maintenance,the study combines with a practical project;reasonably selects materials and wet wheel wear test,load wheel sand test,rutting deformation test;determines the road performance of modified emulsified asphalt slurry seal mixture and the optimal oil-stone ratio of 6.5％;and tests the maintenance effect with flatness,impermeability and skid resistance.The final results show that the roughness,impermeability and skid resistance of the road surface after the slurry sealing layer maintenance have improved by about 25.20％,94.36％and 43.84％,respectively,and the effect is good.
