碩士 === 國立成功大學 === 土木工程學系碩士在職專班 === 104 === Due to the global climate change in the increasing temperature and rainfall, traffic-safety improvement on pavement by using safer and less-noise making material is necessary. Porous Asphalt Concrete, PAC and Stone Mosts Asphalt, SMA are worth considering option for the pavement. Traditional aggregates are made from nature material which is however become fewer and fewer. In the response to the global energy shortage and to the sustainable national development, by-product, Basic Oxygen Furnace (BOF) of converter steel production process under high temperature in steel plant is used. The now detect experiment results showed that PAC by its porosity has great water permeability and noise reduction ability, and is able to significant reduce Equivalent Property Damage Only (EPDO), indicating that PAC is suitable pavement for highway. Whereas, SMA with the ability to extend the pavement durability. However, a long-term observation on follow-up performance is required.
