近几年来,洛阳市在公路建设中不断改建和新建高等级路面以适应迅速增长的交通量的需要。由于我市地质结构复杂,路基稳定性差,而石灰土结构强度低,水稳性差,因此我们针对我市的路面现状,结合当地的地理和自然资源条件,试验推广了强度较高、水稳性较好的稳定水泥粉煤灰砂砾基层这一典型结构,取得了显著的经济效益,有效的防止了反射裂缝的产生。
In recent years, Luoyang City, in highway construction, continuous reconstruction and construction of new high-grade surface to meet the needs of the rapid growth of traffic. Due to the complexity of geological structure in our city and the poor roadbed stability, the strength of lime-soil structure is low and the water stability is poor. Therefore, in light of the current situation of our city’s pavement and the local geographical and natural resource conditions, The better stability of the typical structure of cement fly ash gravel base has achieved significant economic benefits, effectively preventing the generation of reflective cracks.
