废渣在公路建设中的利用现状与发展

Utilization and Development of Waste Residues in Highway Construction

介绍近几年公路建设中对各种废渣的利用及取得的科研成果,其中包括工业废渣、建筑废渣、公路养护大中修产生的废渣。随着我国现有大量的高等级公路多已进入大修期,沥青面层和半刚性基层水泥就地冷再生、泡沫沥青就地冷再生将会广泛应用。

This paper introduces the utilization of various waste residues in highway construction and research results achieved in recent years,including industrial residue,construction wastes and the waste produced in highway medium and heavy maintenance.With a lot of higher-class highways having been in heavy maintenance in China,cement cold in-place recycling and foamed asphalt cold in-place recycling will be widely applied for asphalt surface and semi-rigid base.
