摘要:
由于水稳定性不足造成的水损害,是我国沥青路面早期破坏的主要形式之一.但工程实践表明,浸水马歇尔试验与路面的实际状况相差较远,其残留稳定度也未能反映出沥青混合料水稳定性的真实情况.本文以劈裂试验为基础,通过对浸水条件的改进,进一步深入地研究了几种常见沥青混合料的水稳定性,提出了以真空循环饱水条件下的沸煮劈裂试验的残留稳定度来评价沥青混合料的水稳定性.试验结果表明,此方法的试验结果明显好于现行规范中的方法,而采用密实结构AC-16I的水稳定性明显优于其他几种沥青混合料.
Abstract:
Water damage of asphalt pavements due to insufficient moisture susceptibility has become one of the major types of early destruction. Practice on projects indicates that immersion Marshall test doesn’t accord with the actual in-place condition and that residual Marshall stability is not reliable. Based on freeze-thaw cycle indirect tensile test, a further study of moisture susceptibility for some familiar graded HMA mixtures is carried out through modification of immersion conditions, and a new method of boiled indirect tensile test under vacuum saturation cycle for appraising moisture susceptibility of HMA paving mixtures is put forward. The test results show that the new method is more reliable than that in the present criterion and the moisture susceptibility of AC-16I is distinctly superior to other kinds of asphalt mixtures.
