不同胶结料大粒径透水性沥青混合料性能评价
|
摘要
大粒径透水性沥青混合料是以粗集料骨架结构为典型特征的沥青混合料,具有优良的高温稳定性。目前已在山东省的高速公路、普通干线公路及路网改造工程中得到大面积的推广应用。大粒径透水性沥青混合料不仅具有排水功能,而且作为基层要承受交通荷载,因此对沥青的要求也比较高,要求粘度较高而且要具有良好的高温性能。目前省内普遍采用MAC改性沥青作为大粒径透水性沥青混合料的胶结料,随着改性技术和工艺的发展,橡胶沥青也以高粘弹、较低价格的优势开始应用推广,结合LSPM的性能特点,对不同沥青胶结料类型进行系统研究,寻找性价比最优的胶结料,对促进LSPM的进一步推广意义重大。
本文首先进行了四种不同沥青胶结料的性能对比分析与大粒径透水性沥青混合料的配合比设计,然后通过动态模量(Dynamic Modulus Test)试验、动态三轴试验(Dynamic Triaxial Test)等评价了不同胶结料大粒径透水性沥青混合料的高温力学性能及抗剪强度,建立了相应的动态模量预估模型。结合性能、经济因素对不同胶结料在大粒径透水沥青混合料中的应用特点及前景进行了论证分析。研究表明,MAC改性沥青较基质沥青具有明显的高温性能优势,较SBS改性沥青性价比更优,橡胶沥青作为高粘弹、低成本产品,用于大粒径透水性沥青混合料具有良好的高温性能,应用前景良好。
Characterized by coarse aggregate skeleton structure, large-stone porous asphalt mixture (LSPM) performs excellent in terms of the high temperature stability. LSPM now has been widely applied in high way, common trunk highway and road network reconstruction projects in Shandong province. Functioning as the base, due to the attribute as larger voids structure, LSPM shows outstanding drainage function. At the same time, in order to achieve the endurance of heavy traffic load, LSPM requires a higher viscosity binder which also has good performance in high temperature. Multi-grade asphalt cement is currently widely used in the Shandong province as a large-stone porous asphalt mixtures binder. With the technical and technologic development of modification technology and manufacture, Crumb Rubber Modified Asphalt which has high viscosity, lower price has begun to be widely promoted and applied. Focusing on the key characters of LSPM performance, through the systematic research of several different types of asphalt binder, in order to find out the one with optimal cost performance shall have its great significance.
This paper starts by taking the comparative study as an approach to analyze the otherness among four different types of asphalt cements. At the same time, gradation designs of LSPM have been carried out. Afterward through the "Dynamic Modulus Test" and "Dynamic Triaxial Test" and other comparative studies the dynamic mechanical properties and shear strength of large-stone porous asphalt mixture at high-temperature have been evaluated; the corresponding dynamic modulus prediction model has also been established. Synthesized the outcomes of with performance, economic factors on the different cementing material in large-stone porous asphalt mixture characteristics and prospects of the application of argumentation analysis, studies show that, compared with base asphalt, Multi-grade asphalt cement has the advantage as the better high temperature performance.; compared with SBS modified asphalt, Multi-grade asphalt cement is more cost-effective. As a high-viscosity, low-cost products for large-size water-permeable asphalt mixture, rubber asphalt has good high temperature performance and application prospects.
