| This study was performed to establish the process mean which is statistically satisfying the critical limit of deformation strength $(S_D)$, which is found to reflect rutting characteristics of asphalt mixture relatively well. The process means were determined using the critical $S_D$ values (3MPa for local highway and 4MPa for arterial highways), which were obtained from correlation analysis of APA and $S_D$ test data of actual highway projects, and coefficient of variation of 32 combinations of domestic mixtures. The process means of 3.2 MPa for local highway and 4.25 MPa for arterial highways were suggested when using 3 specimens (diameter of 100mm). However, since these values are based on the loading speed of 30mm/min, the higher values, 3.5 MPa for local highway and 4.5 MPa for arterial highways, were suggested, respectively, if the loading speed of 50mm/min is applied using the old Marshall machine, which should give higher test values. |
