由于沥青质量、供应和价格方面的问题,近年来水泥混凝土路面得到了较迅速的发展,1988年新增的里程超过了2000公里。随着水泥价格的回跌和供应改善,混凝土路面发展的势头将继续保持。混凝土路面的初期投资大,使用年限长,损坏后难以修复,因此,保证混凝土路面的修建质量、使用性能和使用寿命,对于顺利推广和发展混凝土路面至关重要。本文拟围绕混凝土路面的适用场合、路面结构设计、施工和养护以及使用性能监测等方面,讨论健康发展混凝土路面的一些技术问题。
Due to asphalt quality, supply and price problems, cement concrete pavements have seen rapid development in recent years, adding more than 2,000 km of mileage in 1988. As cement prices fall back and supply improves, the momentum of concrete pavement development will continue. The initial investment of concrete pavement, long service life, hard to repair after the damage, therefore, to ensure the construction quality of concrete pavement, performance and service life, for the smooth promotion and development of concrete pavement is essential. In this paper, some technical problems about the healthy development of concrete pavement are discussed in the aspects of the application of concrete pavement, the pavement structure design, construction and maintenance, and the monitoring of service performance.
