中文摘要：
针对现有马歇尔试验方法在抗裂层材料应用中研究的不足,根据旋转压实试验结果进行不同次数的马歇尔击实试验,以孔隙率作为评价指标,确定了抗裂层材料马歇尔试验最佳击实次数为双面击实75次.通过将旋转压实和马歇尔试验结果进行回归,并结合抗裂层材料特点和相关技术规范,确定了适用于抗裂层材料马歇尔试验的技术要求,得到了最佳油石比为7.5％,与旋转压实试验结果7.6％接近.试验结果表明：研究的抗裂层材料马歇尔试验方法具有一定的准确性和可靠性.研究结果可为科学合理地确定抗裂层材料最佳油石比和抗裂层材料在我国道路提质改造中的推广应用提供重要参考.
英文摘要：
According to the research shortage of Marshall test method in anti-cracking material application,in accordance with results of gyratory compaction test for different number of Marshall compaction test,with porosity as evaluation indexes,the best compaction times of Marshall test of anti-cracking layer material was determined as double compaction 75 times.Through the regression of gyratory compaction test and Marshall test results,and combined with the characteristics of anti-crack material and related technical specification,determined the technical requirements of Marshall test which is suitable for anti-cracking layer material,got the optimal asphalt content was 7.5％,which was close to gyratory compaction test results 7.6％.The experimental results showed that：the research of Marshall test method for anti-cracking material has certain accuracy and reliability.The study results can provide important reference for determining the optimal asphalt content of anti-cracking material and the popularization and application of anti-crack material in road reconstruction project.
