【摘要】：本论文以斯里兰卡CKE项目为依托,针对海外地理、气候、工程和市场环境的特点,对路面沥青混凝土配合比设计和施工质量控制进行了研究。首先,一般性的,从沥青混合料的配合比设计入手,对原材料的主要技术性质进行了检测。在此基础上,结合当地的环境条件和施工生产实际情况,对目标配合比和生产配合比进行了设计,并对生产配合比进行了试验验证。试验表明该生产配合比下的沥青混凝土路面录用性能符合规范要求。其次,结合斯里兰卡CKE项目的特点,对海外公路工程施工组织和成本控制进行了研究。施工组织设计需要考虑到机械设备运输、材料采购、人员安全和思想教育等方面。成本控制也需要结合海外材料市场和当地人工市场的环境,海外采购市场与国内市场价格差距不小,同时还要考虑海关通关等费用。人工市场价格一般比较低廉,但是需要通过分包方式进行管理。最后,针对斯里兰卡CKE项目试验路施工和室内试验,提出了施工工艺和质量控制与评价的标准。通过对施工质量的控制,对面层检测指标进行了数据分析,结果表明该施工质量良好,符合规范要求。
[Abstract]:Based on the Sri Lankan CKE project and the characteristics of overseas geography, climate, engineering and market environment, this paper studies the mix design and construction quality control of pavement asphalt concrete. Starting with the mix ratio design of asphalt mixture, the main technical properties of raw materials are tested. On this basis, combined with the local environmental conditions and actual conditions of construction and production, the target mix ratio and production mix ratio are designed. The test results show that the performance of asphalt concrete pavement under the production mix ratio meets the requirements of the specification. Secondly, considering the characteristics of Sri Lanka CKE project, The construction organization and cost control of overseas highway projects are studied. The construction organization design needs to take into account the transportation of machinery and equipment, the procurement of materials, Personnel safety, ideological education and other aspects. Cost control also needs to be combined with the environment of the overseas material market and the local labor market. The price gap between the overseas purchasing market and the domestic market is not small. At the same time, we also have to consider customs clearance and other costs. The labor market price is generally relatively low, but it needs to be managed by subcontracting. Finally, in view of the Sri Lankan CKE project test road construction and indoor testing, The construction technology and the standard of quality control and evaluation are put forward. Through the control of construction quality and the data analysis of the test index of the opposite layer, the result shows that the construction quality is good and meets the requirements of the code.
