通过研究凸石水泥稳定粒料基层,可以提高路面结构层间粘结的强度和可靠性,对提高我国高速公路抗水平剪切能力,延长高速公路使用寿命有很大意义。本文通过室内凸石技术研究实现基层表面凸石,进而以凸石剂剂量和凸石深度为指标对凸石水泥稳定粒料基层的表面特性做深入研究,综合考虑各项性能,推荐最佳凸石剂剂量和最佳凸石深度。
Through the study of the convex aggregate cement stabilized aggregate base layer, it can improve the strength and reliability of the bond between the pavement structures. It is of great significance to improve the anti-horizontal shear capacity of the expressway in our country and extend the service life of the expressway. In this paper, through the study of indoor convex stone technology to achieve the primary surface of the stone, and then the dose of convex stone and stone depth as an indicator of the convex surface of the cement stabilized gravel grassroots surface properties in-depth study, considering the performance, recommended the best convex Stone dosage and optimal stone depth.
