在公路修建过程中,土是路基工程填筑最常用的材料,它造价低廉,施工工艺简单。路基压实情况经常影响公路施工质量,如何达到施工压实标准,克服由于压实原因带来的路基不均匀沉降,是公路工程施工中急待解决的重要问题。路基压实度是保证路面质量的基础,它承受着本身岩土自重和路面重量以及由路面传递下来的车荷载。压实度是路基路面施工质量的关键指标之一,最佳含水量的控制是保证路基压实度的关键,压实在最佳含水量+2%时进行压实最为合适。碾压层厚度必须与所用压实机械的功能相适应,施工前应该针对具体碾压层所用的材料和所用压实设备,通过铺筑试验路段来选择合理的碾压速度和碾压遍数,从而提高压实度保证工程质量。本文就影响路基压实的因素和控制方法进行分析和讨论。
In the process of highway construction, soil is the most commonly used material for embankment construction, which has the advantages of low cost and simple construction process. Subgrade compaction conditions often affect the quality of highway construction, how to achieve compaction standards for construction, to overcome uneven compaction caused by subsidence due to compaction, highway construction is an urgent problem to be solved. Subgrade compaction is to ensure that the basis of pavement quality, it is borne by its own weight and pavement weight and the road load passed by the car. Compaction degree is one of the key indicators of subgrade construction quality. The optimal control of water content is the key to ensure subgrade compaction. Compaction is most suitable for compaction at the optimal water content of + 2%. The thickness of the compacted layer must be compatible with the function of the compaction machinery used. Before the construction, the materials used for the concrete layer and the compaction equipment used should be selected before pavement construction to select the reasonable rolling speed and the number of rolling compaction, To improve the degree of compaction to ensure project quality. This article analyzes and discusses the factors affecting the roadbed compaction and control methods.
