根据相变材料的潜热特性,在前期相变调温剂调温原理和性能指标研究的基础上,参照行业相关规范的技术要求,在原材料优选、技术指标测试的基础上,通过混合料配合比设计,制备掺与未掺微胶囊型相变调温剂MPT-H的AC-13沥青混合料试件,分析了相变调温剂掺量、矿料级配组成等因素对混合料调温效果、马歇尔技术指标及混合料路用性能的影响规律,有效解决了混合料路面调温效果和路用性能之间的矛盾,为自调温沥青混合料应用与大范围推广奠定基础。
According to the latent heat characteristics of phase change materials, on the basis of the research on the temperature control principle and performance index of the phase change temperature control agent in the earlier stage, with reference to the technical requirements of relevant industry specifications, based on the selection of raw materials and technical indexes, Design and preparation of AC-13 bituminous mixture with MPT-H mixed with non-micro-capsule phase change temperature control agent, analysis of the phase change temperature agent dosage, the composition of ore grade and other factors on the temperature control of the mixture Effect, Marshall technical indicators and road mix performance of the law to effectively solve the mixing effect of pavement temperature control and road performance between the contradictions for the application of self-tune asphalt mixture and lay a foundation for a wide range of promotion.
