Abstract:: ln orler to clarily the inllueneing relationship of asphalt components and other factors on the viseos.ity, four - component analysis data and viseositly test data of ten asphalt binders were tested. Based on the greyincidenee analysis, the gray correlation degree sort results of asphaltene, aromaties, salurates , resin, totaconlent of resin and asphaltene ,the content ratio between resin and asphaltene and other factors on the viseosity at 135 9 and 100 ℃ were analyzed. The research results showed that satisfactory results can be golten whengrey ineidenee analysis was used in studying the inlluenee of asphalt components on the viseosity at 135 ℃C and100 C. For the viseosity at 135 ℃ , the grey relation sequenee of inlluenee factors is that resin conlent, aro-matie content, salurate content, tolal of resin and asphaltene, ratio between resin and asphaltene, and as.phaltene content. The sequenee data got by the grey relation degree theory show that the resin content is theprineipal inluenee factor for the viseosity at both temperature, while the asphaltene eontent has a minimum inluenee. The analysis showed that resin content and tolal of resin and asphaltene have important effeet on theviseosity with higher temperature in construction process and workability of asphalt binder.
