【摘要】：從水泥路面與瀝青路面早期病害調查情況來看,層間脫空和層間不粘結或粘結力小是造成路面早期損壞的重要原因之一。因此,對水泥混凝土路面和瀝青混凝土路面的基層、底基層和面層進行早期預防性養(yǎng)護,填充層間脫空和加固層間粘結,提高路面整體承載能力,封閉面層裂縫,防止水分下滲到路面結構層內(nèi),可大大減少后期路面的損壞,延長道路使用壽命。為此,本論文在水泥注漿等國內(nèi)外研究的基礎上,進行室內(nèi)試驗,優(yōu)化各項性能指標,成功研發(fā)適合路面結構補強的地聚合物注漿材料。其性能較傳統(tǒng)水泥注漿材料有流動性好、強度高、凝結時間短、無泌水性和收縮性好等優(yōu)點。結合理論分析與試驗工程檢驗,對地聚合物注漿進行非開挖結構補強加固與病害處治施工工藝研究,確定地聚合物注漿技術的施工工藝及注漿施工設計參數(shù)(注漿壓力、注漿孔布設形式、注漿孔距等)。通過實體工程應用研究,提出地聚合物注漿處治施工質量驗收標準。依托實體工程,通過對路面進行非開挖式結構補強與病害處治,舊路面病害得到較為徹底的處治,提高了病害處路面的殘余強度,且病害處治后的路面性能達到同一道路完好路面的技術標準。該注漿處治技術對病害處治針對性強、修復時間短、維修費用較傳統(tǒng)工藝顯著降低,對于大交通量的公路養(yǎng)護具有明顯的社會意義和經(jīng)濟效益,是一種行之有效的道路加固處理方法。
[Abstract]:According to the investigation of the early disease of cement pavement and asphalt pavement, one of the important reasons for the early damage of pavement is interlayer void and non-bond between layers. Therefore, for the cement concrete pavement and asphalt concrete pavement base, the base course and the surface of the early preventive maintenance, filling between the void and consolidation layer bond, improve the overall bearing capacity of the pavement, close the cracks in the surface, Preventing moisture from penetrating into pavement structure layer can greatly reduce the damage of pavement and prolong the service life of road. Therefore, on the basis of domestic and international research, this paper has carried out laboratory tests, optimized various performance indexes, and successfully developed geopolymer grouting materials suitable for pavement structure reinforcement. Its performance is better than that of traditional cement grouting material, such as good fluidity, high strength, short setting time, no bleeding and good shrinkage. Combined with theoretical analysis and experimental engineering inspection, the construction technology of reinforcement and treatment of diseases of geopolymer grouting structure is studied, and the construction technology and design parameters (grouting pressure) of geopolymer grouting technology are determined. Grouting hole layout, grouting hole spacing, etc. Through the application research of solid engineering, the acceptance standard of construction quality of geopolymer grouting treatment is put forward. Relying on the solid engineering, through strengthening and treating the road surface with non-excavated structure, the disease of the old pavement is treated thoroughly, and the residual strength of the pavement in the diseased area is improved. And the pavement performance after the disease treatment reached the technical standard of the same road intact pavement. The grouting treatment technology has strong pertinence, short repair time, lower maintenance cost than traditional technology, which has obvious social significance and economic benefit for highway maintenance of large traffic volume. It is an effective method for road reinforcement.
