1977年10月,我们在学习河南省交通局利用油灰土铺筑油面的经验以后,曾用粉沙土、天然料、河沙和河砂砾铺筑了一组油路面层试验路。这组试验路由七个不同矿料种类或不同配合比的路段组成,全长414米,其具体情况如表1及表2所示。铺筑这组试验路的目的,是希望能够充分利用区内各种各样的矿料,广开料源,因地制宜,就地取材,为油路面层铺筑探索新的途径。 试验路铺好六个月后(即1978年4月),对其外观情况、密实度、抗滑性能、强度、水稳性和热稳性等曾进行过全面的检
In October 1977, after studying the experience of Henan Bureau of Communications in using oil-soiled soil to lay oil surfaces, we paved a series of oil-road surface test roads with silt, natural materials, river sand and river gravel. The test route consists of seven sections of different mineral types or different proportions, with a total length of 414 meters. Table 1 and Table 2 show the specific conditions. The purpose of paving this set of test roads is to make full use of various kinds of ore materials in the area, to widen the sources of materials, to adapt to local conditions, to obtain materials locally and to explore new ways to pave oil pavement. Six months after the test road was paved (ie, April 1978), a thorough inspection of the appearance, density, anti-skid performance, strength, water stability and heat stability was conducted
