While precast cement mortar block has often been used in modular pavement, precast HMA (Hot Mix Asphalt) block has the advantages of flexible behaviour, no curing and recycling, etc. In this project, the mechanical characteristics of the precast HMA block were evaluated by comparing with precast cement mortar block. The objective of this project was to develop a method for the design of precast HMA block and the evaluation of its mechanical characteristics. The research contents include proportion design and preparation of precast HMA block, mechanical test of precast HMA block, comparative analysis between precast HMA block and precast cement mortar block. Through analysis on the mechanical characteristics of precast HMA block with non-reinforced and reinforced, the research results have indicated that the bending strength of precast HMA block decreases gradually with the increase of aggregate diameter. The comparative results have further indicated that the bending strength of precast HMA block can match the strength of the precast cement mortar block and that it can be applied in modular asphalt pavement. The precast HMA block has provided a feasible technology in modular pavement option.

尽管预制水泥砂浆砌块经常用于模块化路面，但是预制HMA（热混合沥青）砌块具有行为灵活，不固化和可回收等优点。在本项目中，预制HMA砌块的机械特性通过与预制水泥砂浆块相比。该项目的目的是开发一种用于预制HMA块的设计及其机械特性评估的方法。研究内容包括预制HMA砌块的比重设计与制备，预制HMA砌块的力学性能测试，预制HMA砌块与预制水泥砂浆砌块的对比分析。通过分析非增强和增强的预制HMA砌块的力学特性，研究结果表明，预制HMA砌块的抗弯强度随着骨料直径的增加而逐渐减小。比较结果进一步表明，预制的HMA砌块的抗弯强度可以与预制的水泥砂浆砌块的强度相匹配，并且可以应用于模块化沥青路面。预制的HMA块提供了一种可行的模块化路面选项技术。
