TREC Final Reports
The Oregon Department of Transportation (ODOT) Pavement Services Unit is in the process of implementing a new pavement design procedure being developed under the sponsorship of the American Association of State Highway and Transportation Officials. Fatigue cracking is a key distress mechanism that is predicted as part of the overall process using a theoretical model calibrated to empirical data. Tensile strain at the underside of the hot-mix asphalt pavement layers induced by truck axle loads is, in turn, a key input into the fatigue cracking model. In the new design procedure tensile strain is predicted utilizing a layered elastic analysis …
