Abstract

Abstract:

　　By blending -slight oxidation and slight oxidation process, the optimum process conditions could be obtained by testing the effects of penetration of feedstock , oxidation temperature , air velocity flow and oxidation time on hydraulic asphalt products using domestic and imported crude oil as feedstock .A high quality hydraulic asphalt with good high or low temperature performances and aging resistance used in water conservancy construction w as developed.The test results show that the permeability coefficient of imported hydraulic asphalt mixture and domestic hydraulic asphalt mixture are 1.14 ×10^-9 cm/ s and 2 .35 ×10^-9 cm/s;the Marshall stability after aging are increased 14.80 % and 14.28 %;the Marshall value under 60 ℃ are decreased 18.10 % and 6 .19 %;water stability factors are 0.874 and 0 .969 ;and the flexure ratio of bend test under 16.4 ℃ are more then 5 .4 % and 3 .7 %, respectively .It is demonstrated that the asphalt concrete is a hydraulic asphalt with good bending ability , aging resistance ,water stability and penetration resistance .
