【摘要】 <正> 随着我国公路交通事业的迅猛发展,对道路沥青的需要量逐年增加,在质是上也提出了更高的要求。但目前我国主要油区的原油还不能大量地生产出性能良好的道路沥青,制取性能良好的道路沥青已成为当前急待解决的课题。78年,我们与石油化工研究院605组以及一室原油评价组等共同协作对大庆道路沥青组成、结构及沥青的调制等方面作了些工作。更多还原

【Abstract】 This paper describes the relationship between the compositions and the performance of Daqing road asphalts by using triangular diagram, and it is found that in the triangular diagram there exists a definite composition region where the demands of road asphalt specifications can be satisfied. The same rule applies for blending of different asphalts.A structural investigation of the constituents of Daqing asphalt was carried out by proton magnetic resonance spectroscopy. The molecular structures of the asphalt are expressed in terms of carbon-type distribution derived from proton distribution, elementary analysis and molecular weight data.更多还原
