摘　　要：基于半柔性路面材料灌浆工艺的独特性,为探究坡率对其灌注率及路用性能的影响,采用3种不同流动度的灌浆料,在5个设计坡率下制备半柔性路面试件。通过计算和试验,系统评价了坡率对半柔性路面材料灌注率、高温稳定性、水稳定性及抗滑性能等关键指标的影响规律。结果显示,随着坡率的增加,半柔性路面材料的灌注率和水稳定性呈下降趋势,而高温稳定性则先增大后减小。坡度对半柔性路面构造深度的影响显著,坡率越大,坡底和坡顶的构造深度差异越大,抗滑性能受到不利影响。针对上述问题,研究提出了施工工艺优化措施,并通过室内试验加以验证。Due to the unique grouting process adopted by semi-rigid pavement materials,to investigate the effect of slope on their grouting rate and road performance,semi-rigid pavement specimens were prepared using three different fluidity grouts at five designed slopes.Through calculation and experimentation,the influence of slope on key indicators such as grouting rate,high-temperature stability,water stability,and skid resistance of semi-rigid pavement materials was systematically evaluated.The results showed that with the increase of slope,the grouting rate and water stability of semi-rigid pavement materials showed a decreasing trend,while the high-temperature stability first increased and then decreased.The slope had a significant effect on the construction depth of the semi-rigid pavement,and the greater the slope,the greater the difference in construction depth between the bottom and top of the slope,which adversely affected the skid resistance performance.For the above problems,optimization measures were proposed for construction processes and verified them through indoor experiments.
