随着我国国民经济的飞速发展,交通量日渐增加,对公路路面提出了愈来愈高的要求。过去的沥青表面处治路面已远远不能适应汽车数量的增加和行驶速度的需要,高等级公路路面已在全国各地受到普遍重视,修建里程不断增加。 高等级公路路面的结构类型一般均采用沥青碎(砾)石混合料或沥青混凝土路面,这种路面具有良好的使用质量,可大大提高车速、降低油耗。但沥青面层由于直接承受
With the rapid development of our country’s national economy, the traffic volume increases day by day, putting forward higher and higher requirements on the road and pavement. In the past, the asphalt surface treatment road surface has been far from being able to meet the need of increasing the number of vehicles and the traveling speed. The high-grade highway pavement has been widely valued all over the country and the construction mileage has been continuously increased. The structure types of high-grade highway pavement generally use asphalt crushed (gravel) stone mixture or asphalt concrete pavement, which has a good quality of use, which can greatly improve the speed and reduce fuel consumption. However, the asphalt surface due to direct
