【摘要】 叙利亚绝大多数的机场路面都是坚硬的硅酸盐水泥混凝土,在最近几年里这些机场(跑道,滑行道…)都面临着翻新的需要,一方面是由于本身已达到了设计寿命,另一方面是由于新增的降落飞机总重。这一研究将尝试引入中国在翻新机场路面时所采用的添加新的柔性层(柔性盖层)的技术,并且将以哈尔滨国际机场为例讨论这一方法。这一研究将着重于现有硅酸盐水泥混凝土路面上热拌沥青(HMA)盖层的设计。首先,论文将讨论机场路面表层的常见破损(结构性的,功能性的)及其原因。这一研究还将对现有的硅酸盐水泥混凝土机场路面进行结构及功能评估,然后依照美国联邦航空局的标准设计出一种在硅酸盐水泥混凝土路面上敷设热拌沥青盖层的方法,此外还将展现出哈尔滨国际机场的路面评估效果以及现有硅酸盐路面所存在的各类问题的原因。此外,本文还通过分析机场路面所采用的热拌沥青的特性以及机场路面与公路路面之间的不同对设计盖层材料时的最优方法进行了细致的讨论。最后,通过查阅哈尔滨国际机场所采用的热拌沥青盖层的设计以及2006年进行调查时所获得的结果来推测沥青玛蹄脂碎石混合料盖层投入使用后4年的情况。更多还原

【Abstract】 Most of the airports pavement in Syria are rigid; Portland Cement Concrete, inthe last several years a rehabilitation of these airfields ( runways, taxiway,.. ) isneeded because most of them has reached it’s designed life time or because of theincreasing weight of new landing aircrafts.The research will try to get use of technology used in China to rehabilitate theairports pavement by adding a new flexible layer ( flexible overlay ) and willdiscus HarbinInternationalAirport as an example of this procedure.This research will concentrate on the design of a Hot Mixed Asphalt ( HMA )overlayon an existing Portland Cement Concrete ( PCC ) pavement.At first this thesis will discuss the common distresses could be seen in airportspavement surface ( structural, functional ) and the cause of these distresses.The research also will discuss the structural and functional evaluation of anexisting PCC airfield pavement and then the design method of a HMAoverlay onPCC pavement according to Federal Aviation Administration in the U.S. and willshow the result of Harbin International Airport pavement evaluation and thereasons of the problems shown in the existing PCC pavement.And it will elaborately discuss the optimum methods for designing the materialsto be used in the overlay by showing special specifications of the hot mixedasphalt to be used in the airfield pavement and the difference between airportsand highways pavement .Then will browse the HMA design for the overlay used in Harbin InternationalAirport and the results of the investigation which carried out in 2006 todetermine the situation of Stone Matrix Asphalt ( SMA) overlay after 4 years ofbeing in use.更多还原
