摘要

本研究採用新鋪面材料-「永續之傳統瀝青混凝土」，其黏結料係為水泥與瀝青材料之結合，亦可稱為水泥瀝青膠漿，其膠漿可添加工業副產物(飛灰及爐石)又兼具環保性質，不需加熱、常溫即可施工，其固結之混合料剛性介於瀝青混凝土與水泥混凝土之間，可因鋪面之需求，調整工程性質使符合現況之所需而延長使用壽命，因此符合永續之觀念。本研究添加卜作嵐材料(飛灰、爐石)來降低水泥用量，可因卜作嵐材料及水泥水化物中氫氧化鈣與水作用產生卜作嵐反應，進而提升混凝土之力學性質及耐久性能。
研究結果顯示：力學性質方面，添加飛灰與爐石之水泥瀝青混凝土其力學性質明顯優於無添加之水泥瀝青混凝土。耐久性質方面，各組數據皆都符合滯留強度指數規範75%之要求，顯示添加卜作嵐材料於水泥瀝青膠漿中對水泥瀝青混凝土之工程性質與行為有幫助。

The study focuses on developing new pavement materials- "Sustainability of conventional asphalt concrete", the bonding material system for the combination are cement and asphalt, mix in cement asphalt mastic, the mastic was added to industrial by-products (fly ash and slag) and environmentally-friendly nature, without heating, temperature can be construction. The rigidly of consolidation of the mixture was between the asphalt concrete and concrete. The pavement may be improved engineering properties and extend the service life, therefore meet with the concept of sustainability. This study added pozzolan materials (fly ash, slag) to reduce the amount of cement. Due to pozzolan materials and cement hydrates in the role of calcium hydroxide and water produced pozzolan reaction, and thus enhance the mechanical properties of concrete and durability.
The results showed that: the asphalt concrete added fly ash and slag. It’s superior mechanical properties of asphalt concrete without added. Durable of each set of data were in line with standard retention index of 75% strength requirements, added pozzolan material displayed on the cement asphalt mastic in the cement asphalt concrete engineering properties and behavior of help.
