  • The Effect of Evotherm on Hot Mix Asphalt

    the results at 100˚C to 115˚C in Figure 6 satisfying most of the design parameters.. Figure 7 shows the result with optimal performance. The mix is at 1% Evotherm content by weight of binder and 5% Bitumen content by weight of binder. The bitumen content of 5% is the least acceptable for a wearing course design as specified by Nigerian Standard.
