摘要:
利用自主研发的实验室沥青发泡装置,在155,165,175 ℃温度下,将中石油AH70和国创AH70两种沥青进行发泡.研究表明:在可发泡温度范围内,同一温度下产生的泡沫沥青,随着发泡用水量的增加,膨胀率先出现增大,后降低现象.当温度超过175 ℃时,在适当用水量范围内,用水量一定,膨胀率随发泡温度升高出现衰减.气压对半衰期的影响没有用水量对半衰期的影响大,只有在1%加水量的条件下,气压对试验结果有显著的影响.本设备在温度为175 ℃、用水量为2.75%时,达到最佳发泡效果,膨胀率和半衰期分别为14.3倍和
Abstract:
By means of self-developed laboratory asphalt foaming device, two kinds of AH70 asphalt materials were studied under three temperatures 155 ℃,165 ℃ and 175 ℃. It is showed that: under 150-175 ℃, the expansion ratio increases firstly and then decreases as the water content increases; under the temperature more than175 ℃ and proper water content, the expansion ratio decreases as the temperature increases. The influence of pressure on half life is less than the influence of water content, only under 1% water content, the pressure influences the significantly on the test results. Under 175 ℃ and 2.75% water content, the asphalt of AH70 has the best foaming properties, meanwhile, the expansion ratio is 14.3 and half life was 10.8 s.
