橡胶沥青同步碎石封层技术在机场跑道改造中的应用

Application of Rubber Asphalt Synchronous Macadam Seal Technology in Airport Runway Reconstruction

从首都机场跑道大修工程实际出发,为减低和延缓反射裂缝对跑道加铺路面的影响,延长跑道使用寿命,此次改造采用了橡胶沥青同步碎石封层技术。重点分析了该技术施工质量控制要点以及橡胶沥青同步碎石封层在机场跑道改造施工中的优势,在机场改造施工中满足机场不停航施工的特殊要求,降低了施工对机场运行的影响。

In order to reduce and delay the influence of reflection cracks on runway surfacing and prolong the service life of runway,rubber asphalt synchronous crushed stone sealing technology was adopted in this retrofit based on the actual condition of overhauling runway in Capital Airport.The main points of the construction quality control and the advantages of the rubber asphalt synchronous gravel seal in the reconstruction of the airport runway are emphatically analyzed.And the special requirements of the non-stop construction of the airport are satisfied in the airport reconstruction construction.It is of great significance to reduce the influence of construction on airport operation.
