格林纳达圣乔治国际机场跑道沥青盖被不停航全断面摊铺施工工艺

Construction Technology of Full-Section Paving of Runway Asphalt Overlay of St.George International Airport in Grenada

结合格林纳达圣乔治国际机场跑道升级改造项目,针对跑道盖被工程中不停航施工的要求,从沥青混合料设计、盖被宽度、横坡度及机械数量等方面对无冷纵缝全断面摊铺施工工艺进行了分析研究,确定了机场道面沥青盖被不停航全断面摊铺施工工艺。实践表明,该工艺可在满足机场不停航施工条件下保证施工质量满足设计要求。

Combined with the runway upgrade and reconstruction project of St.George International Airport in Grenada,it is aimed at the requirement of non-suspend air construction in the runway overlay project.The construction technology of full-section paving without cold longitudinal joints is analyzed and studied from the aspects of asphalt mixture design,overlaywidth,transverse slope and number ofmachines.The construction technology of full-section paving of asphalt pavement on airport pavementwithout non-suspend air is determined.Practice has shown that this process can ensure that the construction qualitymeets the design requirements under the non-suspend air construction conditions of the airport.
