通过开展室内加速紫外老化试验和冻融试验分析环氧薄层抗滑铺装材料的耐候性。经过模拟9年的紫外老化效果和20次高低温冻融循环后环氧铺装材料仍保持很好的拉拔强度。试验证实了环氧薄层抗滑铺装材料具有良好的抗紫外老化性、温度收缩兼容性和耐候性，不会因为温度变化和紫外老化而产生粘结失效、集料脱落和脱层等严重问题。

The weathering resistance of thin epoxy overlay materials was investigated by using UV aging test and freezing and thawing test.After subjected to 9 -year UV aging effect and 20 freezing and thawing cycles,the overlay still remained good pull-off strength.Test results confirmed that thin epoxy overlay materials have good UV aging re-sistance,temperature shrinkage compatibility and weathering resistance,which are important to prevent adhesion fail-ure,loss of aggregate and debonding.
