A semi-flexible pavement is a pavement designed to prevent plastic deformation due to loading. In order to achieve this performance, it is necessary to be adequately filled with cement grout into gap in porous asphalt pavement. However, the evaluation method for the filling ability of cement grout has not been established yet. In order to evaluate the filling ability, a funnel test is usually used. And in Japan, a P-funnel test is used for it. However, this test method is not for evaluating the filling ability but the viscosity of cement grout.
In this study, by using several types of cement grout with different viscosity, the relationship between filling ability and results of several kind of testing method was investigated. Based on the results, it was found that table-flow test was more suitable for evaluating method than a funnel test.
