摘要
采用Multi-Head Breaker(MHB)碎石化处理技术对旧水泥混凝土路面进行处理,以消除沥青混凝土加铺层的反射裂缝。结合试验路段的实施,对MHB破碎后路面进行沉降观测、回弹模量及回弹弯沉测试,并对MHB破碎效果及其对路基的影响进行了分析与评价。
Portland cement Concrete Pavements are treated by Multi-Head Breaker （MHB） rubblization technique to prevent reflective cracking in the asphalt cement pavement overlay. The settlement, modulus of resilience and deflection are tested to analyze the rubblizing effect and the influence of rubblizing on the subgrade in the test section of highway.
