Road making material comprising PVC, a method of producing said road making material and a road made therefrom

A method for making a road surface from a road making material, the method comprising:

• (a) heating aggregate;
• (b) heating bitumen;
• (c) mixing the aggregate and the bitumen to form an aggregate and bitumen mixture;
• (d) adding a plastics material to the aggregate and bitumen mixture;
• (e) mixing to incorporate the plastics with the aggregate and bitumen mixture to form a mixture of plastics, aggregate and bitumen to form an aggregate, bitumen, and plastics material mix;
• wherein the plastics material comprises at least 80% polyvinylchloride (PVC) by weight;
• and wherein a ratio of the bitumen to the plastics material is from 9:1 to 19:1 by weight;
• and
• (f) laying the mixture of plastics, aggregate and bitumen to form a road surface, and
• wherein the aggregate, bitumen, and plastics material mix comprises from 2.4% to 5.89% of the bitumen with the proviso that:
• the bitumen is in an amount from 4.7 wt. % to 5.69 wt. % of the weight of the aggregate, bitumen, and plastics material mix for the road making material to be 10 mm stone mastic asphalt;
• the bitumen is in an amount from 3.1 wt. % to 4.09 wt. % of the weight of the aggregate, bitumen, and plastics material mix for the road making material to be 6 mm, 10 mm, or 20 mm asphaltic concrete;
• the bitumen is in an amount from 4.9 wt. % to 5.89 wt. % of the weight of the aggregate, the bitumen, and plastics material mix for the road making material to be hot rolled asphalt;
• or
• the bitumen is in an amount from 2.4 wt. % to 3.39 wt. % of the amount of the aggregate, the bitumen, and plastics material mix for the road making material to be heavy duty 32 mm.
