【摘要】 对SMA-16,AC-16Ⅰ,AK-16Ⅰ,单一粒径4.75,9.5,13.2,16等沥青混合料进行了马歇尔试验、车辙试验,以及低温弯曲试验.根据试验结果对这几种混合料进行了高温稳定性、低温抗裂性能分析,认为SMA-16及单一粒径级配均具有较好的抗车辙能力,要优于AC-16Ⅰ和AK-16Ⅰ.低温弯曲试验结果表明,SMA-16要比单一粒径级配、AC-16Ⅰ和AK-16Ⅰ性能优越.SBS改性沥青对沥青混合料的路用性能有一定改善作用.更多还原

【Abstract】 Based on the Marshall,rutting & low temperature banded testing results of SMS-16,AC-16I,AK-16I,with single diameter coarse aggregate grading,their anti-rutting and anti-cracking ability has analyzed in the paper.According to the conclusions,the anti-rutting ability of SMA-16 and single diameter is better than that of AC-16I and AK-16I.The results of low temperature bended testing has been proven that the anti-cracking ability of SMA-16 is superior to that of AC-16I AK-16I and single diameter coarse aggregate grading.The testing results has also proven that the modifiler SBS can improve the performance of asphalt on some extent.更多还原
