摘 要：通过对沥青玛蹄脂碎石混合料、多碎石沥青混凝土、密级配沥青混凝土进行的一系列路用性能试验研究，包括高温变形特性、水稳性、低温抗裂性、抗疲劳特性以及抗滑特性试验，结果表明沥青玛蹄脂碎石混合料具有优良的路用性能。

Porous asphalt concrete is composed of asphalt mastic, coarse aggregate, thin aggregate, stuff and admixture. Such a combination is expected to fully integrate these materials. In this way, the function of interlocking among particles can be performed, a firm net of porous asphalt framework formed and the ability to resist rut and wear developed. The different mixture results in different effects; the quality is so complicated that the factors that cause damage are multiple. Therefore, it is bothersome to choose one material that can be adjusted to various conditions everywhere, such as the traffic volume, load and the weather. The current study mainly investigates and analyzes the main factor that caused flaws after the roads paved with porous asphalt concrete have been open. The analysis aims to search for the best solutions, promote the quality, prolong its availability and finally reach the purpose of complete use.

多孔隙沥青混凝土依其组成材料由沥青胶泥、粗粒料、细粒料、填充料、添加物等组成，目的是希望藉由以上材料的组合能充分接触，发挥颗粒间互锁作用，形成牢固的连锁网的沥青混凝土架构，发挥粒料本身良好的抗车辙及抗磨损之能力，因添加物的不同所发挥出的效果亦不同，其性质甚为复杂，造成损坏之因素亦属多重性，要择其适用於各地迥异之各种条件，如交通量、荷载及气候环境等因子，极为繁琐，本研究主要探讨及分析已铺筑之多孔隙沥青混凝土铺面，经通车后产生之缺失主要因素，以寻求其最佳解决方案，提升品质与延长使用寿命，进而达到全面使用。

Again, I maintain that we should use the flexural-tensile strain and the vertical shearing stress of the bottom of cover of the joint as the target for the design of the cover structure of asphalt on the old cement concrete. In addition, on the basis of much theoretical analysis, I preliminarily put forward to a designing methods to anchor the old cement concrete road by using dog irons made of iron bars and then covering it using asphalt concrete structure. Finally, through selecting the plan of the cover of the road to be experimented, and making a detailed introduction to the techniques of construction according to the result of theoretical analysis, I know that after anchoring the slabs close to each other with dog irons made of iron, and then cover them using asphalt cement concrete has an obvious effect on preventing and slowing down the reflection cracks in the bituminous concrete skin coat over the old road.
