    • PURPOSE: A roadbase composition in road pavement construction using granite soil as main materials is provided, which reduces the amount of cement needed and generation of radiant energy from road, and permeates water. CONSTITUTION: The composition for road base construction comprises 70-80wt.% of granite soil having more than 90% passage through No.4 sieve, 3-6wt.% of cement for strength, 2-4wt.% of basalt coarse fiber(2-3mm) for acid-base resistance and decrease of shrinkage cracking, 3-5wt.% of rice husks for supportive strength of soil, 2-3wt.% of additives, such as CaCl2, bentonite, sodium gluconate, lignin and surfactant, for adhesive and strength, and 10-12wt.% of water.
    • 目的:提供使用花岗岩土作为主要材料的道路路面施工中的路基构成,减少了所需水泥的数量,从道路产生辐射能,渗透水分。 构成:道路基础施工的组成包括70-80%的花岗岩土壤,通过4号筛,90%以上的通过,3-6%的水泥强度,2-4%的玄武岩粗纤维(2 -3mm),抗酸碱性降低,收缩开裂减少,土壤支撑强度为3-5%,添加剂如CaCl2,膨润土,葡萄糖酸钠,木质素和表面活性剂占2-3%,用于 粘合力和强度,以及10-12重量%的水。
