Estimation of Asphalt Pavement Life
The milling of asphalts concrete (AC) pavement surface refers to the mechanical removal of a part of the pavement surface. In this report, the structural and functional performances of such mill-and-inlay AC pavements were analyzed for six different routes of KDOT and KTA. All test sections were tested with the Falling Weight Deflectometer (FWD) at 50 to 100 feet intervals before milling, after milling, and after inlaying. Ten six-inch wide, eighteen-inch long, full-depth asphalt concrete beams were sawn from four test sections. Fatigue tests were conducted in a third-point flexural loading fashion on those field beams sawn into fatigue test specimens of size: 4-in. wide, 3-in. deep and 16-in. long. Distress models and rational transfer factors were found through the analysis of fatigue test results, deflection data, and historical traffic data to estimate the fatigue damage, functional performance, and rutting susceptibility of the mill-and-inlay pavements. For high traffic pavements, an optimal mill-and-inlay depth based on fatigue can be found.
