宕渣混合料(又称岩渣)。即采石料宕所废弃的不规则的碎石、石屑、泥土等所组成的混合物。其颗粒组成和各类成份差异很大,各料场皆不相同,据调查此石料以前销路不广,各采石料场都有大量堆积,其料价较规格料要低得多。因此利用宕渣混合料作油路的补强层材料,在经济造价方面是可取的,而关键问题则在于是否有足够的强度和稳定性,使之有一定的补强效果。我们对此进行初步的探索和试铺,逐步打开了利用宕渣修建补强层的 Down slag mixture (also known as slag). That is, the quarry dumped irregular gravel, stone chips, mud and other components of the mixture. The particle composition and various components vary greatly, and the material fields are not the same. According to the survey, the stone was not sold well before. The quarries all accumulated a large amount of material, whose material prices were much lower than the specifications. Therefore, it is advisable to use the slag mixture as the reinforcing material of the oil circuit in terms of economic cost. The key issue is whether there is enough strength and stability to make it have a certain reinforcing effect. We conducted a preliminary exploration and trial shop, and gradually opened the use of slag to build reinforced layer
