Low-strength thick plate cement pavement
The invention provides a low-strength thick plate cement pavement. The thickness of a pavement slab of the low-strength thick plate cement pavement is determined according to brittle fracture resistance requirement data, the pavement slab of the low-strength thick plate cement pavement is laid on a soil roadbed, and the pavement slab comprises a stable aggregate base layer (1), a cement concrete surface layer (3) and a surface wear-resistant layer (4); the soil roadbed, the stable aggregate base layer (1), the cement concrete surface layer (3) and the surface wear-resistant layer (4) are paved in sequence. The unconfined compressive strength of the pavement cement concrete of the low-strength thick plate cement pavement is totally lower than the minimum value 30MPa required by Design Specification of Road Cement Concrete Pavement JTG D40-2011, and the low-strength thick plate cement pavement is low in manufacturing cost and long in service life.
本发明提供一种低强厚板水泥路面，所述低强厚板水泥路面的路面板厚度依据抗脆裂要求数据来确定，其路面板厚度依据抗脆裂要求数据来确定，其路面板铺设在土路基上，路面板包括稳定粒料基层(1)、水泥混凝土面层(3)和表面耐磨层(4)，依次铺设的次序为土路基、稳定粒料基层(1)、水泥混凝土面层(3)和表面耐磨层(4)。本发明低强厚板水泥路面的路面水泥混凝土无侧限抗压强度全部低于《公路水泥混凝土路面设计规范JTG D40‑2011》要求的最低值30MPa，低强厚板水泥路面造价低、寿命长。
