摘要
为提高公路路面耐久性,改善不良土质环境的路面使用性能,基于某公路工程,以其不良土质环境中的弱盐渍土路段、黄土(低液限黏土)路段、粉性土路段和砂砾土路段的路基技术状况和路面技术状况进行研究。结果表明,砂砾土路基有最高的结构强度和最佳的路面技术状况,提高路面结构承载力可有效确保路面平整度和使用性能。
In order to improve the durability of highway pavement and improve the pavement performance in adverse soil environment,based on a highway project,the subgrade and pavement technical conditions of weak saline soil section,loess(low liquid limit clay)section,silty soil section and sandy gravel soil section in adverse soil environment are studied.The results show that the sand gravel subgrade has the highest structural strength and the best pavement technical condition,and improving the pavement structural bearing capacity can effectively ensure the pavement evenness and service performance.
