The importance of effective recycling of old crushed pavements has been often pointed out for aggregate shortage and solid waste disposal. To investigate the applicability of asphalt concrete scraped from surface course as base course materials of airport pavement, some kinds of experiments, such as seive analysis, CBR test, Marshall test and unconfined compression test, were carried out.
　As a result, it was ascertained that the scraped material has high quarity and can be considered as asphalt stabilized material if it is heated before repaving.
