摘要:随着我国交通现代化建设不断的迅猛发展,公路建设取得了举世瞩目的成就,当然,随之发生的一些工程质量问题也引起了社会各界的高度重视。近几年,我国对公路工程建设项目也加大了管理力度,从设计、施工、监理等各环节采取了相应措施,但是,目前工程建设质量在一定程度上仍然存在值得注意之处。我国进入WTO以后,工程建设项目即也进入国际市场,我们必须更加提高公路工程的质量意识,使公路建设水平越来越高,结合作者多年的工作经验,本文主要对公路工程路基路面施工质量控制进行了探讨。

Abstract: along with the traffic modernization constantly of rapid development, and highway construction has made remarkable achievements, of course, some of the resulting project quality also caused the social from all walks of life are highly valued. In recent years, our country for highway engineering construction project also increased the strength of management, from design, construction, supervision and so on various links taken measures, however, at present, engineering construction quality in a certain degree is the place of attention still exists. China's entry into the WTO, engineering construction project that is also enter the international market, we must improve the quality of highway engineering more consciousness, which highway construction level more and more high, combining author's work experience, this paper focuses on the highway engineering roadbed construction quality control are discussed in this paper.
Keywords: roadbed construction, quality, technology is discussed

我国高等级公路路基路面所采用的施工工艺已走向规范化和定性化,也更具有科学性,这是公路交通量和路面工程技术发展到一定水平的必然结果。基层质量是在施工工艺中形成的,每一道工序的质量都将影响基层最终质量,控制基层施工质量必须加强施工工艺的质量控制。路面基层施工工艺质量控制,应严格执行路面基层施工技术规范,紧抓各个工序质量控制要点,既针对路面基层的施工工艺进行以下分析。
1、施工质量控制探讨
1.1 路基土的控制探讨
路基一般是用自然土修筑的,在路基填筑之前应对自然土进行试验分析,确定其物理力学性质,测定其最佳含水量及最大干容量,以便指导路基施工及对路基填筑成品的检测,从有关试验结果分析:土质颗粒越细,其相应的回弹模量越低,而砂性土回弹模量比较高。……
