Relying on the asphalt pavement construction engineering from Tianshui to Dingxi,internal and surface temperature of hot asphalt mixture and warm-mix asphalt was measured and the difference between them at different time was discussed.The GM(1,1) model on the temperature variation during hot mix asphalt and warm-mix asphalt paving was established based on the Grey theory.The results show that the surface temperature variation is not obvious for hot asphalt mixture and warm-mix asphalt.After the initial compaction,the internal temperature of asphalt mix was significantly greater than that of the hot mix asphalt;Grey prediction model established of internal and surface temperature variation during warm-mix asphalt pavement paving have high precision,which can be used in the temperature variation of warm-mix asphalt,and it can provide the important reference for warm-mix asphalt pavement paving.
