摘　　要：以水泥冷再生底基层沥青路面为研究对象,利用足尺路面加速加载试验机MLS66对此结构开展加速加载试验研究;对比分析了此结构在抗车辙和承载能力方面与辽宁省高速公路沥青路面常规结构的差异。最后,总结了加速加载试验条件下水泥冷再生底基层沥青路面性能的衰变特点,为在辽宁省公路建设中广泛应用水泥冷再生基层技术提供参考和依据。The paper takes the cement cold -recycled bottom base asphalt pavement （CRAP） as research object and then the CRAP structure has been investigated by the Accelerate Pavement Test （APT） with full - scale APT facility, MLS66; it has been analyzed contrastively that the difference of anti -rut and loading -bearing capacity between the structure and Liaoning provincial typical expressway asphalt pavement structure during the stage of APT loading under same test conditions. By the end, the characteristics of the CRAP structure~ pavement performance deterioration has been summarized so as to provide reference and foundation for wide application of the cement cold - recycled base tech in the area of Liaoning provincial highway construction.
