沥青路面层间水的病害分析与处置

Analysis and Disposal of Asphalt Pavement Interlayer Water Diseases

目前多降雨地区及集中降雨地区沥青路面经常出现局部泛水现象(尤其在桥面铺装上现象明显),并在持续的交通荷载下伴随松散、脱落、坑槽、基层破坏等沥青路面常见病害。查阅相关道路的建设和养护资料,此类情况主要是由于沥青路面层间水所导致,严重降低了驾驶员的行车舒适度与路面日常使用的功能性。怎样做好沥青路面层间水的防排是减轻水损害产生的重要手段,通过理论分析及工程实例针对路面工程设计、施工提出了合理化建议。近年来,我国基础设施和道路建设取得飞速发展,尤其特别是高速公路工程建设等领域的快速发展,一个地区如果没有四通八达的道路和路网,对该地区的经济发展将会产生很大的影响和制约,俗话"要想富,先修路",这样一句话主要是反映出我国自从改革和开放以来的市场化经济现象,便利的公路交通和运输环境使得我们可以大大降低商品经济条件下的物流和运输成本,也推动了我国经济繁荣和快速发展。一、二线城市由于历史原因更快的拥有了属于自己的路网,但限于当时城市规划滞后、技术条件有限以及施工工艺不成熟,各级道路经常出现重建,改建及大、中、小修等情况,无一例外每次施工都绕不开路面工程的翻新及修补工作,作为道路建设领域的一员,近年来多次接触路面的翻新工作,尤其是雨季过后,路面破损情况都会加剧,造成了施工工期紧、任务重的现状,严重浪费了社会资源,加剧了国家负担。通过资料查阅并结合施工现场情况,确定沥青路面层间水的存在对沥青路面质量、耐久性产生大量不利影响,如何解决沥青路面层间水造成的危害,是道路建设领域急需面临的问题。

At present,local flooding often occurs on asphalt pavement in rainy areas and concentrated rainy areas(especially on deck paving),and is accompanied by common diseases of asphalt pavement such as looseness,falling off,pit,base damage and so on under continuous traffic load.Refer to the relevant road construction and maintenance data,such situations are mainly caused by interlayer water on asphalt pavement,which seriously reduces the driver's driving comfort and the functionality of pavement daily use.How to prevent and drain water between layers of asphalt pavement is an important means to reduce water damage.Rationalization suggestions are put forward for pavement engineering design and construction through theoretical analysis and engineering examples.In recent years,China's infrastructure and road construction have achieved rapid development,especially in the field of highway engineering construction.If there is no road and road network in a region,it will have a great influence and restriction on the economic development of the region.The saying"to get rich,build roads first"mainly reflects the market-oriented economic phenomenon since the reform and opening up of China.Convenient highway transportation and transportation environment enable us to greatly reduce logistics and transportation costs under commodity economic conditions,and also promote our economic prosperity and rapid development.First and second-line cities owned their own road network more quickly due to historical reasons,but at that time,due to the lagging urban planning,limited technical conditions and immature construction technology,reconstruction,reconstruction and minor repairs of roads at all levels often occur,without exception,the renovation and repair of road works are indispensable for every construction.As a member of the road construction field,in recent years,they have contacted the road surface renovation work for many times.Especially after the rainy season,road surface damage will be aggravated,resulting in tight construction period and heavy tasks,which seriously wastes social resources and increases the national burden.By consulting the data and combining the construction site conditions,it is determined that the existence of interlayer water on asphalt pavement has a lot of adverse effects on the quality and durability of asphalt pavement.How to solve the hazard caused by interlayer water on asphalt pavement is an urgent problem in the field of road construction.
