Publication: Transportation Research Congress 2017: Sustainable, Smart, and Resilient Transportation
ABSTRACT
In order to research on design method and pavement performance of water injection foamed modified asphalt warm SMA, hot mix modified asphalt SMA-13 mixtures were designed, which could determine mix/compaction temperature, aggregate gradation, and optimum asphalt content. On the base of the above, volume parameters performances, for water injection foamed modified asphalt warm mix SMA mixtures, were conducted. Reasonable mix/compaction temperature and appropriate plant fiber contents were confirmed to research pavement performances for water injection foamed modified asphalt warm mix SMA mixtures. The research results show that compared with hot mix SMA mixtures, pavement performances of water injection foamed modified asphalt warm mix SMA mixtures have no significant change. Plant fiber contents are reasonably reduced as water injection foamed modified asphalt warm mix SMA mixtures is designed, which helps to improve volume parameters and construction workability, and not lead to decline pavement performances. It need be further researched and discussed whether binder drainage test methods, introduced by Chinese standard test methods of bitumen and bituminous mixtures for highway engineering, can be applied for water injection foamed modified asphalt warm mix SMA mixtures.
