A new mix design system for porous asphalt based on maximising the effective void content, but maintaining sufficient strength through the use of polymer-modified bitumen, was developed and trialled.
The skid resistance, permeability, and noise characteristics were compared with those obtained for a control using the current TNZ P/11 mix, and found to be similar or better.
