沥青砼路面再生技术及其在国外的发展

Recycling Technology for Asphalt Concrete Pavement and Its Development in Overseas

对旧沥青砼路面合理再生利用,既节约石料、石油沥青等紧缺资源和节能,降低成本,又可节省占地空间,具有环保意义,近年受到国内外广泛推崇.结合笔者在日本的研究成果,就沥青砼路面的不同再生利用技术中所涉及到的再生工艺、再生混合料配合比设计、再生混合料性能、施工设备配套和质量控制等技术问题作简要介绍.

Recycling and properly utilizing old asphalt concrete pavements has many advantages that can not only conserves diminishing resource of aggregate and petroleum asphalt and save energy, decrease cost, but also lessens occupied sites and protect environment. So it is widely welcomed both in domestic and in overseas. Simply the recycling technique, the mix design, the performance of mixtures, the needed component parts of construction equipment and quality control, etc are presented including different recycling and re-utilizing technology for old asphalt concrete pavement.
