Novel construction method of filling type super-large-particle-size cement stabilized macadam base layer
The invention relates to a novel construction method of a filling type super-large-particle-size cement stabilized macadam base layer. According to the method, a micro-cracking technology is introduced, the construction environment is simulated through an indoor test before construction, exact parameters of the micro-cracking degree of the micro-cracking construction of the filling type super-large-particle-size cement stabilized macadam base layer with the mixing ratio to be constructed are obtained, micro-cracking construction is carried out through certain maintenance after the filling typesuper-large-particle-size cement stabilized macadam base layer is paved, and the target micro-cracking degree obtained through an experiment is achieved. Compared with a filling type super-large-particle-size cement stabilized macadam base layer without micro-cracking construction, shrinkage cracks are effectively prevented, and the service life of a road is remarkably prolonged.
本发明为一种填充式超大粒径水泥稳定碎石基层施工新方法，该方法引入微裂技术，在施工前通过室内试验模拟施工环境，获取将要施工的配合比的填充式超大粒径水泥稳定碎石基层微裂施工的微裂程度的确切参数，在填充式超大粒径水泥稳定碎石基层摊铺完成后经过一定的养护进行微裂施工，使其达到实验所得的目标微裂程度，相比不经过微裂施工的填充式超大粒径水泥稳定碎石基层，有效防止了收缩裂缝的产生，显著提高了道路的使用寿命。
