Influence of Insufficient Subgrade Compactness on Structural Performance of Subgrade and Pavement
In order to study the influence of low compactness on the structural mechanical properties of subgrade and pavement,this paper first takes a highway project as an example to set up two areas of normal compactness and insufficient compactness and compare the dynamic stress of two different subgrade base layers and subgrade top surfaces.The results show that,when the subgrade compaction is insufficient,it will cause the deterioration of pavement structure.Secondly,the influencing factors of subgrade compactness are analyzed,and the effective measures to control the compaction construction of highway subgrade are discussed,aiming to provide help for related work and promote the sustainable and healthy development of highway construction.
