提高水泥稳定风化砂掺碎石混合料基层强度研究

Analysis on Improving the Strength of Mixture Base Mixted with Cement Stabilized Weathered Sand and Crushed Stone

当今,公路建设的快速发展,给人们的生产和生活带来了极大地便利,但是,路面基层早期损坏严重,影响了公路的使用寿命,公路的使用耐久性需要不断地提高。在实际施工过程中,我们遇到了基层级配碎石不均匀、水泥搅拌不匀及含水率稳定等影响基层质量的不稳定因素,我们通过仔细的调查研究,收集相关数据和资料,对出现的各种问题定期以小组研讨会的形式共同探索和研究,查找出现问题的原因,提出切实可行有效的解决方法,对于提高水泥稳定风化砂掺碎石混合料强度有着积极意义,有利于提高公路使用的耐久性。

Today, the rapid development of highway construction, has brought great convenience to people＇s production and life, but pavement base is seriously damaged at the early stage, affecting the service life of the road and the using du- rability of the road needs continue improvement. In the actual construction process, we met many unstable factors affect- ing the quality of the base, including the uneven gravel of basic level, uneven stirring of the cement, and unstable mois- ture content. Through careful investigation and research, we collected relevant data and information, jointly explored and researched the various issues regularly in seminar groups, to find out the causes of the problems, and put forward a feasi- ble and effective solution It is of great positive significance to improve the strength of the mixture of cement stabilized weathered sand and crushed stone, which is beneficial to improve the using durability of highway.
