This paper describes the feasibility of recycling of the aged asphalt collected from membranes that are over service life. We developed a hot press technique to exclude asphalt from an aged roofing membrane. Some fundamental properties of the asphalt such as penetration, softening point and slippage length were clearly lowered. As reductions of resins, aromatics and saturated hydrocarbons were observed through a component analysis, process oil and new asphalt compound were added to the aged asphalt to recover the property. The roofing membrane constructed with the recycled asphalt reached again to the similar level in performance as new one.
