Method for reinforcing pavement by using carbon fiber gridding cloth

HAN SONG / DAI SHAOLEI / TAN CHENG

The invention discloses a method for reinforcing a pavement by using carbon fiber gridding cloth. The method comprises the following steps: (1) flattening and fixing carbon fiber gridding cloth on thesurface of a road base surface; (2) spraying epoxy mortar to coat the carbon fiber gridding cloth; (3) adding a protective layer on the surface of the epoxy mortar after the epoxy mortar is cured; and (4) standing for 7-24 days for maintenance. According to the technical scheme adopted in the method for reinforcing a pavement by using carbon fiber gridding cloth, the carbon fiber gridding cloth is laid on the road base surface, and the epoxy mortar is used for coating the carbon fiber gridding cloth, on one hand, road cracking can be effectively avoided, rainwater is prevented from permeatingand damaging the road base surface, and on the other hand, the carbon fiber gridding cloth has high tensile strength, so that the thickness of a surface layer needing to be reinforced is effectivelyreduced, and once road surface collapse occurs, the carbon fiber gridding cloth can play a crucial role in avoiding serious accidents. In addition, the carbon fiber grids have the characteristics of moisture resistance, corrosion resistance, corrosion resistance and salt spray resistance, long-term maintenance is simple, and the maintenance cost is greatly reduced.

本发明公开了一种碳纤维网格布加固路面方法，包括以下步骤：(1)在道路基面表面抻平并固定碳纤维网格布；(2)喷灌环氧砂浆将碳纤维网格布包覆其中；(3)待环氧砂浆固化后在其表面添加防护层；(4)静置7～24天养护。采用上述技术方案，本发明的碳纤维网格布加固路面方法，在过在道路基面上铺设碳纤维网格布，并且使用环氧砂浆将碳纤维网格布包覆其中，一方面能够有效避免道路开裂，防止雨水渗透损坏道路基面，另一方面碳纤维网格布具有较强的拉伸强度，从而有效降低所需加固面层厚度，一旦发生路面塌陷也能够对避免发生严重事故其中至关重要的作用；另外碳纤维网格具有防潮耐蚀防腐耐盐雾的特性，长期养护简单，极大降低维护成本。
