机场刚性道面是由多块板通过各种接缝连接起来的一个整体,道面缝长约是道面长度的20倍.然而,接缝是水泥混凝土道面最薄弱的部位,因此接缝在整个机场场道工程施工中不容轻视,其施工质量直接影响着机场道面的使用性能、整体强度和使用寿命.通过采用新型接缝形式,改变传统的水泥混凝土道面接缝和扩缝工艺——将宽缝变窄,然后对窄缝进行倒角.这种接缝形式不但能够提高水泥混凝土道面的接缝质量,保护水泥混凝土道面最薄弱的地方——接缝边角,还能增强灌缝材料的黏聚力,减少飞机滑行时的颠簸,增加飞机起飞、着陆时人员的舒适度.该接缝倒角技术对机场场道工程建设具有重要的革新意义,不仅可以降低道面被破坏的概率,减少道面运行后的维修费用,还可以从源头上降低因道面破损而导致飞机发动机吸入破碎物的概率,提高了道面使用的安全性和可靠性,具有明显的经济效益和社会效益.

The rigid pavement of the airport is a whole, which is connected by a variety of joints, and the length of the road is about 20 times the length of the pavement. However, joint is the weakest of the cement concrete road surface parts, so juncture in the airport runway construction can't be ignored; its construction quality directly affects the use of airport pavement performance, the overall strength and service life. By using the new joint form, change the traditional cement concrete road surface joint and expansion of the sewing process -- the wide gap narrowed, and then in the narrow chamfering. This kind of joint form not only can improve the joint quality of cement concrete pavement, protect the weakest place of cement concrete pavement-- joint edge angle, but also enhance the cohesion of the filling material, reduce the turbulence of the aircraft, and increase the comfort of the aircraft during takeoff and landing. The joint chamfering technology of airport runway engineering construction has important significance of innovations can not only reduce probability of road surface is destroyed, reduce maintenance costs of road surface after the operation, can also from the source to reduce because of the breakage of road surface and lead to broken probability of aircraft engine aspiration, improve the safety and reliability of the pavement, and has obvious economic benefit and social benefit.
