| 摘要： | As part of an overall plan to increase the hot mix asphalt (HMA) resurfacing cycle time, the Tennessee Department of Transportation (TDOT) initiated a project to pair aggregate polish resistance with pavement functional needs in 1992. A new pre-evaluation procedure for aggregate polish resistance was developed and named the Tennessee Terminal Textural Condition Method (T(sup 3)CM). Correlations between T(sup 3)CM and pavement skid performance were far superior to the correlations for percent silica and BPN9 to pavement skid performance. Unfortunately, the T(sup 3)CM was labor intensive. |
