摘要
讨论了砾石资源用于公路沥青路面面层的必要性,并且通过破碎砾石的加工及相关集料试验验证其可行性,分析了砾石用于沥青路面的加工要求,得出满足不同公路等级和路面层次的指标适用性划分,为砾石资源的广泛应用提供科学依据。
The necessity of using gravel resources for asphalt road surface of highway is discussed,and the feasibility is tested by processing of broken gravel and relevant aggregate test.The processing requirement of gravel for asphalt road surface is analyzed,and index applicability classification of meeting different highway grades and road surface levels is obtained,thus providing scientific basis for wide application of gravel resources.
