影响WRAM材料设计与路用性能的关键因素研究
|
摘要
为探究温拌再生沥青混合料(WRAM)路用性能关键因素的影响,采用正交试验方法进行路用性能关键影响因素分析,采用方差分析进行关键因素影响显著性评价。结果表明,RAP掺量及温拌剂用量对WRAM水稳定性及高温稳定性影响显著,RAP掺量及RAP颗粒组成对WRAM低温抗裂性影响显著;建议RAP掺量为45%、温拌剂用量2%、RAP组成为5~10mm时,WRAM高温稳定性及水稳定性最佳;建议RAP掺量为15%、温拌剂用量2%、RAP组成为0~5mm时,低温抗裂性及水稳定性最佳。
In order to figure out the key influencing factors on the pavement performance of warm recycled asphalt mixture(WRAM),the orthogonal experiments were carried out to study the issue,and the variance analysis was conducted to assess the significant impact of the key factors.The experimental results show that the additive amount of RAP and warm mixing agent have great impact on the moisture susceptibility and high-temperature stability of WRAM,while TAP content and RAP particle composition on the low temperature anti-cracking performance of WRAM.It is suggested that RAP content be 45%,warm mixing agent 2%,and the RAP particle composition 5-10 mm to achieve the optimal high-temperature stability and moisture susceptibility,and 15%,2% and 0-5 mm respectively for the optimum low temperature anti-cracking performance and moisture susceptibility.
