Design method for additionally paving asphalt surface layer on existing concrete pavement
The invention provides a design method for additionally paving an asphalt surface layer on an existing concrete pavement. The design method comprises the following steps: S1, detecting and evaluating the condition of the existing pavement; s2, determining an additional paving mode of the existing concrete pavement according to the detected slab breaking rate and average slab staggering quantity; s3, determining the paving thickness of the existing concrete pavement according to the detected thickness and flexural tensile strength of the existing concrete pavement; s4, determining an anti-reflection crack design according to the detected seam load transfer capability; s5, according to the additional paving mode, the additional paving thickness and the anti-reflection crack design, determined in the above steps, of the existing concrete pavement, the combination design between the structural layers is determined; and S6, outputting the pavement structure through the above steps. According to the method, through interlayer combination design, the structures form a whole, then the pavement combination design is obtained, and guidance and operability are high.
本申请提供一种既有混凝土路面加铺沥青面层的设计方法，其包括：S1，既有路面状况检测与评定；S2，根据检测到的断板率和平均错台量，确定既有混凝土路面的加铺方式；S3，根据检测到的既有混凝土路面厚度、弯拉强度，确定既有混凝土路面的加铺厚度；S4，根据检测到的接缝传荷能力，确定防反射裂缝设计；S5，根据上述步骤中所确定的既有混凝土路面的加铺方式、加铺厚度以及防反射裂缝设计而确定各结构层之间的结合设计；S6，由以上步骤输出路面结构。本方法通过层间结合设计，使结构组成一个整体，进而得出路面组合设计，其指导性与可操作性强。
