Construction and application of expansion chamfering process of cement concrete pavement for airport
机场水泥混凝土道面扩缝倒角工艺施工与应用

摘要

机场水泥混凝土道面接缝是整个道面施工的重点和难点，质量较难控制，接缝施工工艺要求高，难度大，操作复杂，如果不重视接缝施工质量，改进施工工艺和设备，将会影响接缝的施工质量，造成接缝的破坏。道面扩缝倒角工艺是对传统直角切缝形式的改进，它的应用将减少道面病害，有效地提高道面使用的安全性。现场应用和经济效益分析表明，值得在机场道面施工中推广应用道面扩缝倒角工艺。

Abstract

The airport cement concrete pavement joint is the key and difficult point of the entire pavement construction, the quality is difficult to control, the joint construction process requires high requirements, the difficulty is high, and the operation is complicated. It will affect the construction quality of the joints and cause damage to the joints. The pavement expansion and chamfering process is an improvement on the traditional right- angle slit form. Its application will reduce pavement diseases and effectively improve the safety of pavement use. Field application and economic benefit analysis show that it is worth popularizing and applying pavement expan- sion and chamfering technology in airport pavement construction.
