Study on Basic Properties and High-Temperature Performance of Rice-Husk-Ash-Modified-Asphalt

Article Preview

Abstract:

Currently, many inorganic materials are investigated for modifying asphalts, but biomass ash is rarely applied to the modification of asphalt. In this present work, rice-husk-ash, as a representative of the biomass ashes, was added as a modifier to evaluate the related performance. The result showed that the basic performance, aging resistance, and high-temperature performance of modified asphalt has been improved, which proves that biomass ash can be used as an asphalt modifier for resource reuse.
