碩士 === 國立屏東科技大學 === 土木工程系所 === 100 === With the recent increasing of global environmental consciousness and energy shortages, the bottom ash used in road pavements will become the major trend. The goals of resource recovery and sustainable development can be achieved. Due to high temperature and intensive rain in the Taiwan, the porous asphalt pavements have been adopted gradually in recent years. Besides the rapid drainage of surface water through its matrix, a positive benefit reducing the urban heat island effect is also expected.
Properties of bottom ash and natural aggregate are analyzed in this research. Six proportions of porous asphalt concrete containing natural and bottom ash coarse aggregate are made. In the AC specimens, different weight of natural coarse aggregate are replaced the bottom ash. The coarse aggregate in the proportions are: 100% natural aggregate, 100% bottom ash aggregate, and 10% and 20% of total aggregate eight of singular #4 and 3/8” grains respectively replaced by bottom ash with same size. Each proportion also contains dyeing powder and pulverized slag as filler to study their effects on the AC specimens. Marshall test is held to determine the optimum asphalt contents of the proportion proposed above. The void ratio, permeability, Marshall stabilities and flow values of the AC specimens made in this study are then measured.
The specific gravity is 2.31 of bottom ash coarse aggregate that is lower than 2.62 of natural coarse aggregate. The absorption capacity is 5.32% of bottom ash coarse aggregate that is much higher than 1.27% of natural coarse aggregate. Replacing natural aggregate by bottom ash aggregate will lead increase of the asphalt consumption and cost of the asphalt concrete. Marshall stabilities and flow values of the AC do not reduce when bottom ash aggregate substitution increases. The void ratios and permeability coefficient, both in laboratory and in-situ tests, rises when percentage of bottom ash used increases, and so do the drainage relevant consecutive air voids.
