三门峡专用公路的黑色表面处治,系在级配路面上作双层表面处治。全长30余公里,计188,6千平方公尺,路面宽为5.5公尺,处治层厚度:路面纵坡大于6％铺设s公分,小于6％铺2.5公分,总的设计形变模量要求达到400公斤/平方公分。施工全部系用人工浇洒,在1957年4月下旬开工,其中因七、八月遇到雨季,路线受到水毁,故全部工程延至九月底才全部竣工。从竣工通车后的观察,路表面基本上形成了密实的黑色处治层,使路面不再受大气因素的影响而损坏,从而大大地提高了原级配路面的质
Sanmenxia highway black surface treatment, Department of graded road surface for double-layer surface treatment. Total length of more than 30 kilometers, totaling 188,600 square meters, the road width of 5.5 meters, the thickness of the treatment layer: pavement longitudinal slope greater than 6% s laying, less than 6% shop 2.5 cm, the total design modulus of deformation requirements Reached 400 kg / cm. All the construction was done by artificial spraying and started construction in late April 1957. Due to the rainy season in July and August and the route being damaged by water, all the works were not completed until the end of September. After the completion of the opening to traffic observation, the road surface basically formed a dense layer of black governance, the road is no longer subject to the impact of atmospheric factors and damage, thus greatly improving the quality of the original graded pavement
