| 摘 要： | 国道G212线南部至定水路面改建工程为依托，对共振碎石化的施工技术和工艺进行了研究；根据贝克曼梁测得的弯沉，计算得到G212线南部至定水碎石化层的当量回弹模量范围为215～277MPa，说明其有足够的承载力且模量值较均匀，可作加铺层的基层直接使用。

| Abstract: | Based on Nanbu-Dingshui pavement reconstruction project along National Highway G212, the construction technology and process of resonance rubblization is studied. According to the deflection measured with Benkelman beam, the range of the equivalent modulus of elasticity of rubblization layer thereof could be calculated as 215 -277 MPa, which shows the layer has enough bearing capacity and even modulus to be used as base of the pavement overlay directly. |
