Abstract
Description
technical field
[0001] The invention belongs to the technical field of road engineering materials, and in particular relates to a novel lightweight roadbed material using industrial waste residue and waste foam plastics as main raw materials and a preparation method thereof. Background technique
[0002] In most areas of southern my country, it is a typical wet and soft clay foundation. Its biggest feature is poor water stability and high compressibility. Under the action, the base will be gradually compacted, subsidence or consolidation deformation and uneven deformation will occur, which will lead to excessive deformation and stress increase on the road surface, road cracking, uneven road surface and bridge head jumping and other diseases. , affecting the service life of the road and affecting the comfort of driving.
[0003] To improve the stability of soft soil subgrade, two methods can be adopted, one is to adopt the method of construction and treatment of subgrade, and ...
