%X 多锤头碎石化技术适用于旧水泥路面原位利用&#65292;但缺乏快速、高效的破碎评价方法。本文提出了当量破碎度和当量能量耗散指数双控指标来评价破碎质量&#65292;利用落锤式弯沉仪&#65292;在试验段确定了破碎参数后&#65292;界定了试验段当量破碎度和当量能量耗散指数范围&#65292;并增加了基层和土基对应的辅助指标范围&#65292;评价方法可为采用多锤头碎石化工艺破碎后的水泥路面提供参考和借鉴。<br>Multi-hammer crushing technology is suitable for <i>in-situ</i> utilization of old cement pavement, but it lacks a fast and efficient crushing evaluation method. In this paper, a dual control index of equivalent crushing degree and equivalent energy dissipation index is proposed to evaluate the crushing quality. By using the existing testing equipment FWD, the range of equivalent crushing degree and equivalent energy dissipation index of the test section is defined after the crushing parameters are determined in the test section, and the auxiliary index range corresponding to the base and soil foundation is increased. The evaluation method can provide reference for the cement pavement broken by the multi-hammer crushing process.
