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.
