为解决装配式水泥混凝土道面应用中灌浆层的优选问题，设计了灌浆种类、板底粗糙程度、灌浆厚度和基层结构四因素三水平的正交试验方案，开展了竖向静态和疲劳加载试验以及侧向加载试验.结果表明：板底粗糙程度对灌浆层与面层粘结性能影响最大，灌浆种类对灌浆层与基层粘结性能以及道面结构承载性能影响最大；经疲劳加载后，面层的中性面会出现不同幅度的上移，挠度和压力与疲劳加载次数的关系曲线呈现出剧烈变化、线性变化和稳定3个阶段；侧向荷载作用下，高强无收缩灌浆料(CGM)与基层的粘结性能最好，侧向荷载与上层结构位移满足二次多项式关系.当灌浆材料为CGM、板底光滑、灌浆厚度为 2.0cm、基层结构为12%水泥稳定土时，道面灌浆层的粘结性最好.
In order to solve the optimization problem of grouting layer in the application of prefabricated cement concrete pavement, an orthogonal test scheme with four factors (grouting type, bottom roughness, grouting thickness and base structure) and three levels was designed. The vertical static and fatigue loading tests and lateral loading test were carried out. Results show that the bottom roughness has the greatest influence on the bonding characteristics between the grouting layer and the surface layer. The grouting type has the greatest influence on the bonding characteristics between the grouting layer and the base layer, as well as the bearing capacity of pavement structure. After fatigue loading, the neutral plane of the surface layer exhibits upper shifts in different degrees. The relationship between deflection, pressure and fatigue loading times has three stages: dramatic change, linear change and stable stage. Under lateral load, high strength non-shrink grouting material (CGM) has the best bond with the base. The relationship between lateral load and superstructure displacement meet the quadratic polynomial pattern. When the grouting material is CGM, the slab bottom is smooth, the grouting thickness is 2.0cm, the base structure is 12% cement stabilized soil, the pavement grouting layer achieves the best bonding characteristics.
