Abstract:

In view of the deficiency of the existing research on the effect of gradation segregation on the water damage resistance of asphalt mixture， the effects of various water environment effects and different segregation degrees on the water loss resistance of asphalt mixture were studied based on the moisture sensitivity tester（MIST）. The results show that： the weakening order of water environment on splitting strength and marshall stability is "static immersion + MIST （long-term + short-term effect）" > "MIST （short-term effect）" > "static immersion （long-term effect）"； after the occurrence of gradation segregation， the order of splitting strength and Marshall stability is HC （heavy segregation of coarse aggregate） < LC （mild segregation of coarse aggregate） < D （no segregation） < LF （mild segregation of fine aggregate） < HF （heavy segregation of fine aggregate）； the effect of hydrodynamic environment aggravates the effect of gradation segregation on splitting strength and Marshall stability， and the effect of gradation segregation on water permeability coefficient is much greater than that of water environment.

Key words: road engineering, gradation segregation, moisture damage, moisture induced sensitivity tester, long-term effect, short-term effect, evaluation index
