平整度是路面一项重要的使用性能,是路面施工质量和服务水平的最重要的指标之一,它直接反映路面使用期的舒适性能。不平整的路表面会增大行车阻力,并使车辆产生附加的振动作用,动荷系数大,影响行车的速度、安全以及驾驶的平稳和乘客的舒适,同时也会加剧路面和汽车的磨损,不仅增加油料消耗,而且加速了路面的破坏。平整的路表面要依靠优质的沥青混合料、先进的施工技术来实现。随着高速公路建设的发展,路面的平整度标准也不断提高。平整度这一指标越来越受到重视。根据施工经验和理论分析,提高和保证路面平整度的关键施工技术包括沥青混合料、测量控制、摊铺碾压工艺和施工温度均匀性。仅供参考。
Flatness is an important performance of the pavement, is one of the most important indicators of pavement construction quality and service level, which directly reflects the comfort performance of the pavement. Uneven surface of the road will increase the driving resistance and make the vehicle have additional vibration effect, dynamic load factor, affecting traffic speed, safety and driving stability and passenger comfort, but also exacerbate the road and the car wear and tear, Not only increase fuel consumption, but also accelerated the destruction of the road. The smooth surface of the road to rely on high-quality asphalt mixture, advanced construction technology to achieve. With the development of highway construction, the standard of road surface roughness has been continuously improved. Flatness this indicator more and more attention. According to the construction experience and theoretical analysis, the key construction techniques to improve and ensure the road surface roughness include asphalt mixture, measurement control, paving and rolling process and construction temperature uniformity. for reference only.
