Application of Falling Ball Method Combined with Continuous Intelligent Rolling System in Roadbed Construction
In the process of roadbed compaction,there are some problems,such as over-pressure,under-pres-sure,leakage pressure in some areas,insufficient lap width and so on.This paper introduces the research on the construction quality of roadbed by falling ball method combined with continuous intelligent rolling system.By discussing the technical principle of falling ball method and continuous intelligent rolling system,the rela-tionship between resilient modulus and compaction degree of water-stabilized layer of a highway and the rela-tionship between resilient modulus and compaction modulus are established.The results show that the correla-tion of the above relationship is more than 0.98.When the resilient modulus of the soil foundation reaches 128 MPa and the compaction modulus reaches 54 MPa,the compaction degree can reach the requirement of not less than 96%.Through the application of falling ball method and continuous rolling system,not only is the con-struction quality guaranteed,but also the construction efficiency is improved,and the problems such as over-pressure,under-pressure,partial area leakage pressure and insufficient lap width are fundamentally avoided.
