| Summary: | 碩士 === 國立成功大學 === 土木工程學系碩博士班 === 91 === Taiwan is under sub-tropic zone with high temperature and humid climate. When the asphalt concrete pavement accumulates water will cause the loss of adhesion and cohesion that will produce stripping to affect the durability of asphalt concrete pavement. This will lead to destroy of the structure and decrease the service life of the pavement. Drainage asphalt use large quantity of coarse aggregate, it also has the high percentage air voids from 15% to 25% to displace the water. It is usually the primary choice of the moist region because several advantages like reducing a mist when driving and noises, preventing to hydroplaning in rainy day, increasing driving safety, etc. Although it was used several years in the Europe and the USA with good effects, it is still in research stage in Taiwan. How to develop a suitable drainage asphalt system for ourselves is an important issue. In this study, we use the polymer-modified asphalt and then combine with the Drainage Graded of the USA, Japan, Spanish, and Sweden as experimental materials. First, we use the mix design of The Japan「排水性鋪裝技術指針（案）」to decide the best percentage of asphalt content and then make the mixtures. The mixtures will be evaluated mechanical property by several tests such as Indirect Tension Test、Marshall Stabilometer Test、Wheel-Tracking Test to study the mechanical properties. We expect to find a new category which can use less asphalt content but have higher quality and produce less rutting.
