不同粒径布敦岩改性沥青的低温性能研究
Low-temperature properties of Buton rock-modified asphalt with different particle sizes
摘要
Abstract
The effects of Buton rock asphalt(BRA)and BRA ash of five different particle sizes on the low-temperature properties of asphalt and asphalt mixture were studied by the physical property test,rheological property test,four constituent chemical test,low-temperature bending test and semi-circular bending test.The findings indicated that increasing the particle sizes of BRA and BRA ash contributes to the degradation of the low-temperature properties of the modified asphalts.When the particle size of BRA is the same,the asphalt content of BRA-modified asphalt binder is more than that of the BRA ash-modified asphalt mortar,and the BRA-modified asphalt binder shows worse low-temperature properties than the BRA-modified asphalt mortar.Thus,we recommend to use the BRA with a size of 16.8 μm to prepare the BRA-modified asphalt in consideration of low-temperature properties and economy.关键词
