随着我国社会发展及社会需求的不断增加,高等级公路规模也在进一步扩大。目前,在国内缺乏理想的路基填料状况下,作为一种较少的填料,砂被广泛应用于告诉公路填筑中。由于砂自身低私结性和不易密实的特点,所以,施工质量控制不到位,则会导致后期路面出现开裂,对其适用功能造成直接影响。所以,在施工过程中应与检验工作相结合,确保施工及检测质量,实现路面的经济效益和社会效益。 With the continuous development of social development and social demand in our country, the scale of high-grade highways has also been further expanded. At present, sand is widely used to inform highway construction as a kind of less filler in the absence of ideal subgrade filler in China. Because of its low self-clump sand and difficult to dense features, so the construction quality control is not in place, it will lead to cracks in the late pavement, the application of its direct impact. Therefore, in the construction process should be combined with the inspection work to ensure the quality of construction and testing, to achieve the economic benefits of the road and social benefits.
