Highway pavement structure utilizing waste residues
The invention belongs to the field of pavement structures, and discloses a highway pavement structure utilizing waste residues. The highway pavement structure comprises a subbase layer, a base layer,a lower surface layer and an upper surface layer which are laid from bottom to top, wherein the subbase layer is a cement waste residue stabilized aeolian sand subbase layer; the pavement is simple instructure, the prestressed concrete layer is adopted as the lower surface layer, the advantage of high strength of prestressed concrete is utilized, longitudinal and transverse pressure stress is applied to the pavement by applying oblique prestress, and the flexural-tensile strength of the concrete plate is improved; in the cement stabilized aeolian sand subbase layer, power plant waste residuesare adopted to replace part of aeolian sand so that the compressive strength of the cement stabilized aeolian sand subbase layer is improved, and the 7d unconfined compressive strength of the obtained cement waste residue stabilized aeolian sand subbase layer is 2.0-2.8 MPa; the strength of the cement waste residue stabilized macadam aeolian sand base layer can still meet the requirements of Technical Regulations for Construction of Highway Pavement Base Layers; and power plant waste residues and aeolian sand can be effectively utilized, and the production cost is low.
本发明属于路面结构领域，公开了一种废渣利用的高速公路路面结构，包括自下而上铺设的底基层、基层、下面层和上面层；其中，所述底基层为水泥废渣稳定风积沙底基层；该路面结构简单，采用预应力混凝土层作为下面层，利用预应力混凝土强度大的优势，通过施加斜向预应力，给路面施加了纵、横向的压应力，提高了混凝土的板的弯拉强度；水泥稳定风积沙底基层中采用电厂废渣代替部分风积沙有利于提高其抗压强度，使得到的水泥废渣稳定风积沙底基层7d无侧限抗压强度2.0‑2.8MPa；水泥废渣稳定碎石风积沙基层的强度仍能满足《公路路面基层施工技术细则》要求；且能实现电厂废渣和风积沙的有效利用，生产成本低。
