文档介绍：Road drainage design features
Abstract: With China's rapid economic and social development, road construction has entered a rapid development period. However, increasing traffic and load cases, the use of traditional materials and construction techniques into the road pavement in use revealed many problems, especially in the southern rain-fed areas, roads, water and surface water damage to the phenomenon of performance was very prominent. This has e so foreign road construction of a major difficulty. Therefore, the conventional asphalt concrete pavement in both the design and construction process needs to be improved on. The porous asphalt concrete pavement is adapted to the needs and developed a new type of pavement structure, is particularly suitable for wet areas. This paper briefly studied.
Keywords: porous asphalt concrete, pavement, mix design, construction techniques, quality control
1 Background
With China's rapid economic and social progress, and infrastructure are also at an unprecedented pace, highway construction is the construction of infrastructure facilities one of the key. As of the end of 2005, highway mileage has more than 41,000 km. Although with the new materials and construction process optimization, continuous improvement of the quality of asphalt pavement, but there is still a considerable part of the asphalt concrete pavement in the process of usin
