摘  要:常规方式处理破坏严重的水泥混凝土路面时存在效率低、费用高的缺点,目前我国逐渐采用冲击压实设备进行破碎的工艺,山东省公路局近年又引进了MHB(Multiple HeadBreaker,多锤头破碎机)类水泥混凝土路面碎石化(Rubblization)设备。本文主要从破碎效果对2种设备进行对比,通过2种工艺破碎后表面回弹弯沉及回弹模量等测试数据,分析2种工艺处治后结构层表面的强度变异性。结果显示,MHB设备破碎的水泥混凝土路面具有更好的强度均匀性,可以作为新加铺路面的基层。When deteriorated concrete road is to be reconstructed,it usually takes too much time and money using ordinary equipment in our country.Recently,the impact compaction equipment,known as Landpac,has been used for this purpose and the MHB(Multiple-Head Breaker) equipment has been brought by transportation department of Shandong province.This paper mainly compares the two types of equipment used for breaking deteriorated concrete road.Through the test data of resilient vertical displacement and resilient modulus,the intensity variation of broken slab using this two equipment are analyzed and compared.It is shown that the MHB equipment can bring a surface which has equal or better intensity,this can be used as base
