滑板测粘方法在评价沥青低温性能方面的应用

采用力学模式比较清晰的自制低温滑板粘度计测定了沥青低温条件下的粘度值，验证了国家“八五”科技攻关课题“道路沥青及沥青混合料路用性能的研究”提出的沥青低温性能评价指标Ｐ．Ｉ和Ｔ１．２的有效性，同时在沥青和沥青混合料之间建立了更合理的联系．应用这一试验方法不仅可以评价沥青低温性能，更重要的是可由沥青低温特性预测沥青混合料的低温性能。

APPLICATION OF TEST METHOD OF DETERMINING VISCOSITY WITH SLIDING-PLATE VISCOMETER IN APPRAISING LOW TEMPERATURE PROPERTY OF ASPHALT

By means of self-made sliding-plate viscometer, which has a more distinct mechanic model, the low temperature viscosity of asphalt is determined, the appraising index about low temperature property of asphalt, that is P. I and T1.2, is verified, meanwhile, the more reasonable relation betWeen the bituminous binder and bituminous mixture is established. Using this kind of cest method not only can appraise the low temperature property of asphalt, but also,more importantly, can forecast the low temperature property of bituminous mixture from the low temperature property of asphalt as well.
