Long-acting road structure
The invention provides a long-acting road structure which comprises a surface layer, a base layer and a subbase layer, the surface layer is a cement asphalt concrete layer, and the base layer is a modified soil base layer; the modified soil base layer is a mixture of cement, lime or asphalt and on-site original soil; the stabilized soil is at least one of asphalt stabilized soil, cement stabilized soil, lime stabilized soil and lime industrial waste residue stabilized soil. By means of the long-acting road structure, the material strength of a subbase layer, a base layer, a surface layer and the like of a road can be effectively improved, the elastic modulus is enhanced, the pavement bearing flexural deposition value is reduced, tension cracks at the bottoms of all layers of the pavement are restrained, the permanent deformation amount generated by plastic deformation is reduced, the factors of pavement damage are reduced, and the service life of the pavement is prolonged. And the purpose of prolonging the service life of the road is achieved.
本发明提供一种长效道路结构，包括面层、基层和底基层，所述面层为水泥沥青混凝土层，所述基层为改性土基层；所述改性土基层为水泥、石灰或沥青与现场原土的混合；所述稳定土为沥青稳定土、水泥稳定土、石灰稳定土、石灰工业废渣稳定土中的至少一种。通过本发明的长效性道路结构，能够有效改善道路底基层、基层及面层等的材料强度、强化弹性模数、减少铺面承载弯沈值及抑制铺面各层底部张力裂缝产生，并减少因塑性变形产生的永久变形量，使铺面损坏的因素减少，以达到延长道路使用年限的目的。
