中文摘要：

通过室内试验研究了国产环氧沥青混合料在低温环境条件下的施工和易性、容留时间范围,以及强度增长规律等施工控制特性.选取芯样空隙率和试件马歇尔稳定度作为评价施工质量的性能指标;通过轮碾试验模拟实际施工过程中的碾压成型过程;选择马歇尔试验和布氏粘度试验研究强度增长特性.试验结果表明：国产环氧沥青混合料可以在10℃的低温环境条件下进行施工;混合料在120℃的容留温度条件下最长容留时间达到70min;在国产环氧沥青混合料完全固化以前,混合料强度随着时间和温度的增长而不断增长. 最后,用有机化学理论分析了国产环氧沥青混合料强度增长规律的理论依据.

英文摘要：

The construction controlling elements,including construction performance at low ambient temperatures,reserved time ranges,and the strength increasing rule,for locally developed epoxy asphalt mixture（LDEAM） are studied through laboratory tests.Air void and Marshall stability are chosen as the performance measures for evaluating the construction quality.The wheel rolling test is used to simulate the actual construction situations,while the Marshall test and the Brookfield viscosity test are adopted to study the strength increasing rule.The experimental results reveal that the LDEAM can be constructed under a low ambient temperature condition of 10℃,and its longest reserved time is 70 min at a reserved temperature of 120℃.Test also shows that the strength of the LDEAM increases with time and temperature before cured.Finally,the theoretical reason for the strength increasing rule is analyzed on the basis of the organic chemistry theory.
