Enhancing Texas Mechanistic-Empirical Flexible Pavement Design System (TxME) Practice: Develop Enhanced Mix Aging Model and District-Level Calibration Guidance
The research team will update the Flexible Pavement Design System (FPS) to FPS23, integrating the Texas Mechanistic-Empirical Flexible Pavement Design System (TxME) to enable Districts to compare long-term performance with the Mechanistic-Empirical (ME) design process. The research team will (a) review protocols that accelerate laboratory mix aging process, (b) evaluate test methods that are more accessible to Districts, (c) develop a mix aging model, (d) identify key parameters to input into TxME, (e) conduct comparisons between FPS and TxME designs, and (f) support Districts by providing calibration methods, factors, or means for straightforward determination of parameters representative of local materials, mix designs and traffic conditions.
