Overlay Only

In this alternative, no milling is considered. The only design variable is the thickness of the overlay. Since the new overlay will be placed directly on the existing AC that is cracked, it is required to model the pavement with reflective cracking.

 

Note: Polymer modified mix is chosen instead of RHMA-G mix because the required RHMA-G with PG58-22 base binder for the High Desert climate of this project is relatively less common. Since RHMA-G with PG58-22 base binder is currently not available in CalME Standard Materials Library, please contact the headquarter if it is preferred to use RHMA-G in high desert and high mountain.
