Design of Polymer Modified Asphalt Mixes for

An alternative design was made using polymer modified asphalt. In that case 50 mm dense graded polymer asphalt had to be laid on 150 mm open graded polymer asphalt. All in all this meant a substantial reduction in asphaltic material and a sharp reduction in the needed amount of scarce good quality aggregates.
