摘要
为使钢桥面铺装材料的关键指标得到更为广泛的认可度,针对莫桑比克马普托大桥,分别采用国内试验方法和欧洲通用试验方法与技术指标对铺装材料高温稳定性进行试验研究,并对中欧试验评价方法进行对比分析。结果表明,马普托大桥采用的浇注式沥青混合料和高弹SMA混合料其高温性能均能同时满足中欧2种评价指标。经过对比发现,虽然国内评价指标更加苛刻,但是欧洲评价方法更为接近铺装材料真实服役情况。
In order to make the key indicators of steel bridge deck paving materials more widely recognized,a test and study is conducted on the high temperature stability of pavement materials of the Maputo Bridge in Mozambique by respectively using China and Europe common test methods and technical indicators which are also comparatively analyzed.The results show that the high temperature performance of both the cast asphalt mixture and the high-resilience SMA mixture used in the Maputo Bridge can meet both China and Europe evaluation indexes.Although the China evaluation indexes are stricter,the evaluation method in Europe is closer to the actual situation of paving materials.
