Optimization of Construction Technology Based on Graded Gravel Base of Low-Grade Highway
Low-grade roads mainly refer to rural roads and rural roads with low traffic volume,simple pavement structure,generally using graded gravel as the base.Graded gravel base has a good bearing ca-pacity,but there are some problems,such as segregation,cracks,deformation and so on.In order to im-prove the construction quality and performance of low-grade highway graded gravel base,it is optimized the graded gravel scheme,and put forward the optimization scheme of mixing,paving,rolling,and other construction technologies.
