Abstract
Recently, the demands for polymer modified asphalt type-H (“PMA-H”) are growing and its usages are being varied as performance-based specification is more widely adopted in pavement contracts, and also due to implementation of laws concerning quality assurance of public works. Accordingly, the issue of quality guarantee of PMA-H is increasing its importance than ever. In order to materialize quality guarantee of PMA-H, evaluation of quality deterioration through all the related processes is indispensable, namely, manufacturing of PMA-H, manufacturing of mixture, paving, actual service and even regeneration. Among such processes, evaluation for quality deterioration of PMA-H in storage process is important because it has much influence on it's quality guarantee period. Our studies this time was made with the purpose of figuring guarantee-able period of PMA-H quality in storage, by examining its quality deterioration up to mixture manufacturing, which is the start point of the whole PMA-H usage procedure. (Our indoor pilot equipment was utilized therefor.)
