共振碎石化在城市道路改造中的应用

Application of Resonant Lithotripsy in Urban Road Reconstruction

水泥混凝土路面在以往的城市道路建设与公路建设中广泛应用,而旧水泥混凝土路面直接加铺沥青路面存在着反射裂缝的问题,对道路的使用性能与年限有较大影响。以娄底市中心城区湘阳街改造工程为依托,对其进行共振碎石化后再加铺沥青路面,通过对碎石化层,改造后的沥青路面的检测和后期观察发现共振碎石化技术可基本解决道路的反射裂缝问题,为碎石化技术在以后的城区道路改造中的应用提供了经验。

Cement concrete pavement has been widely used in city road construction and highway construction.However,asphalt pavement directly applied to the old cement concrete pavement can result in reflective cracks problems,which greatly influence the functional performance and service life.Based on the project of Loudi central city Xiangyang street engineering,this article finds out a basic solution to reflective cracks problems,after resonance lithotripsy and adding asphalt pavement to the road,through the test and later observation of gravels and remould asphalt pavement.It can provide experience for the application of resonant lithotripsy in urban roads reconstruction.
