【摘要】：為了給低溫條件下環(huán)氧瀝青混合料道面設(shè)計(jì)提供理論依據(jù),通過室內(nèi)試驗(yàn),研究了環(huán)氧瀝青混合料低溫開裂性能及性能評(píng)價(jià)指標(biāo).通過瀝青混合料多種低溫評(píng)價(jià)指標(biāo)適用性分析,建議低溫劈裂強(qiáng)度作為評(píng)價(jià)環(huán)氧瀝青混合料低溫抗裂能力的指標(biāo);寒冷地區(qū)新建的環(huán)氧瀝青道面結(jié)構(gòu)設(shè)計(jì),以低溫開裂臨界溫度-31℃作為考慮面層低溫開裂的設(shè)計(jì)指標(biāo),以低溫劈裂強(qiáng)度作為結(jié)構(gòu)設(shè)計(jì)控制指標(biāo).結(jié)果表明,環(huán)氧瀝青混合料在低溫條件下蠕變速率小,塑性差,但低溫抗裂性能較好,抗拉強(qiáng)度是同類型改性瀝青混合料的1.3~2.0倍,勁度模量為1.3~1.9倍.
[Abstract]:In order to provide theoretical basis for pavement design of epoxy asphalt mixture under low temperature, the cracking performance and performance evaluation index of epoxy asphalt mixture at low temperature were studied through laboratory tests.Through the applicability analysis of several low temperature evaluation indexes of asphalt mixture, it is suggested that the low temperature splitting strength be used as the index to evaluate the low temperature crack resistance of epoxy asphalt mixture.The critical temperature of low temperature cracking (-31 鈩，
