本规范涵盖按性能分级的热浇沥青裂缝密封剂。性能分级后，热灌沥青裂缝密封剂将被指定密封剂等级（SG）名称（例如SG 52-16）。级配名称与表1所示的平均7天最高路面设计温度和最低路面设计温度有关。

This specification covers hot-poured asphalt crack sealant graded by performance. Upon grading for performance, the hot-poured asphalt crack sealant will be assigned a sealant grade (SG) designation (e.g., SG 52-16). Grading designations are related to the average 7-day maximum pavement design temperature and the minimum pavement design temperature shown in Table 1.
