摘　　要：城市生活垃圾焚烧MSWI(Municipal Solid Waste Incineration)是一种常用的无害化处理技术。MSWI底渣是垃圾焚烧后产生的残留物的主要组成部分,分别对掺加0、10%,20%.30%MSWI底渣的沥青混合料的路用性能进行了试验研究和分析。结果表明,当MSWI底渣的掺量增加时,沥青混合料的高温稳定性先增强后减弱,掺10%底渣时达到最佳;低温抗裂性逐渐提高,而水稳定性逐渐减弱。综合考虑各种因素,推荐混合料中底渣的最佳掺量为10%。MSWI(Municipal Solid Waste Incineration)is a common harmless treatment technology.MSWI bottom ash is the main component of the residue after MSWI incineration.The high temperature pavement performance of asphalt mixture with 0%,10%,20%and 30%MSWI bottom ash was studied.By the basic physical and chemical properties of MSWI bottom ash and limestone rock debris and by the Marshall stability test and rutting test,it shows that the high temperature stability of MSWI bottom ash increases first and then decreases with the increase of MSWI bottom slag content,low temperature crack resistance is gradually improved and water stabilityis weakened.Considering all kinds of factors,the optimum content of bottom slag in mixtures is recommended to be 10%.
