Discussion on two kinds test method of simulative for asphalt heating ageing in blending process 浅论模拟沥青加热拌和老化的两种试验方法
It is found that, after heating to simple β phase and quenching in water, immediate ageing for 30~ 60 minutes at β_1 phase can bring about stable shape memory effect and martensite thermoelasticity. 试验结果表明:将合金加热到β单相区淬火后,立即在β1状态时效一定时间(30~60min),可获得稳定的形状记忆效应,并保持马氏体热弹性特征。
Based on the perdurable performance of the asphalt pavement are influenced by water, heating, ultraviolet radiation, this paper studies the water stability, heating ageing and ultraviolet radiation ageing of bituminous mixtures. 基于水、热和紫外线对沥青路面耐久性的影响,针对沥青混合料浸水、受热老化和紫外线老化三个方面进行研究。
POE not only has high elasticity, strength, elongation and good cryogenic property, but also has good heating ageing resistance and ultraviolet resistance. 聚烯烃弹性体既有高弹性、高强度、高伸长率和良好的低温性能,又有优异的耐热老化和抗紫外性能。
