摘要
在香港,所有建筑废弃物必须统一回收、分离与利用。小于50 mm的物料主要用于填土(因为含泥量高);大于50 mm的物料经破碎后,可用于道路路基工程、制砖材料,甚至混凝土结构工程;分离出来的塑料板、纤维板、木屑、纸片等废弃物则必须进行掩埋。利用破碎粘土砖取代一定量的再生混凝土集料,可配制道路基层的混合料,其级配、强度(或CBR值)均满足道路基层材料的要求。
All building wastes must be uniformly reclaimed, separated and utilized in Hong Kong. The wastes with size less than 50 mm are used in the fill-land （as clay content is high）. Those wastes with size more than 50 mm, after they are crashed, can be used in road sub-base engineering, made brick, also, used in concrete structure engineering. While the wastes for plastic-board, fiberboard, wood and waste paper must be buried under the ground, When crashed clay brick replacea certain of recycled concrete aggregates, the blended sub-bases can be produced and their performances （grade, strength and CBR value） meet needs used in road sub-base.
