Abstract

Based on the actual project of cement pavement reconstruction and expansion of composite pavement grouting treatment to widen the joint, three professional grouting companies were commissioned to develop three different grouting schemes for the 200 m grouting test section to grout the widening joints. Meanwhile, the reinforcement effect of the pavement was tested by employing such methods as the falling weight deflectometer (FWD), geological radar, pavement core drilling, and on-site pavement structure slotting. By comparing and analyzing the dynamic deflection and radar reflection detection results, on-site core sampling, and on-site pavement excavation conditions before and after the grouting of the test section, the effect of the three cement grouting schemes in treating widening cement pavement joints was evaluated. The results show that scheme of utilizing cement grouting for treating widening joints of cement pavement can produce certain effects in local loose and hollow areas within a certain diffusion radius, and can quickly and effectively improve the pavement bearing capacity in the short term. Additionally, pavement radars can be adopted as a detection tool to evaluate the cement grouting effect of widening joints of cement pavement.
