Described is a method of manufacturing a road comprising providing a binder comprising a plastic source, the plastic source comprising 15 to 40% by weight of a plastic that comprises a styrene unit, 20 to 45% by weight of a second plastic source being (1) a plastic having a styrene unit or (2) a styrene monomer, 5 to 35% by weight of an acrylate monomer, 5 to 30% by weight of a multifunctional monomer, and a promotor and cross linkercombining the binder with an aggregate to coat said aggregate, the aggregate having a moisture content of less than 6% by weight, provided a moisture control aid is also present, or less than 3% by weight moisture if a moisture control aid is not present, laying the mixture onto a roading base course at a thickness of between 50 to about 200 mm; and compacting the layer.
