Pavement Service Life Extension Due to Asphalt Surface Treatment Interlayer

The main objectives of this study are to evaluate the Louisiana Department of Transportation and Development (LADOTD’s) current Asphalt Surface Treatment (AST) interlayer practice over soil-cemented base courses; determine the effectiveness of the AST interlayer practice in terms of its costs and benefits; develop statistical performance prediction models for each distress type of flexible pavement with and without AST interlayer over; and to develop guidelines/policies for the use of AST interlayers over soil-cement base.
