What is HDM-4 Road Deterioration Model Insights about?

The document discusses pavement ages used in the HDM-4 road deterioration model. It notes issues with resetting all ages to zero after thin overlays in HDM-3. It proposes changes to HDM-4 such as resetting AGE2 but not AGE3 after thin overlays less than 50mm thick. It also suggests resetting rut depth to a nominal value if AGE3 is not reset after a treatment where rut depth was previously zero.
