The study on mix proportion design of asphalt mixture mixed with broken gravel instead of macadam in an arid & desert region has been the hot topics of the study made by scientifi c research and engineering technical personnel. The analysis results of the broken gravel asphalt mixture proportion design in the arid & desert region show that the testing indicators of the broken gravel materials meet the requirements of the high grade highway pavement specifi cations, both water stability and high temperature stability of the broken gravel asphalt mixture meet the requirements of the high grade highway pavement specifi cations and that the mix proportion deign of broken gravel asphalt mixture in stead of macadam asphalt mixture has great popularization and application value.%干旱荒漠区破碎砾石代替碎石进行沥青混合料配合比设计研究一直是科研与工程技术人员研究的热点。通过干旱荒漠区破碎砾石沥青混合料配合比设计分析，结果表明：破碎砾石原材料检测指标满足高等级公路路面规范要求；破碎砾石沥青混合料水稳定性、高温稳定性检测指标满足高等级公路路面规范要求；用破碎砾石代替碎石进行沥青配合比设计有较大的推广应用价值。
