The present invention refers to a process for the production of an additive composition intended to be mixed into a bituminous conglomerate for road paving. The process includes grinding a mixed waste material containing a mixture of plastic materials, which includes at least one plastic material based on a polyolefin thermoplastic material, washing the ground mixed waste material and separating a portion of low-density material which contains the plastic material based on a polyolefin thermoplastic polymer from the mixed waste material. This portion of low-density material is then ground to a particle size between 10 mm and 20 mm; and then mixed with a material based on polyvinyl butyral. The resultant mixture is further ground to produce an additive composition having a particle size between 4 mm and 6 mm.

A process for the reuse of oilfield drilling waste with an natural affinity for oil which has had at least a portion of the contaminants removed using a remediation technology. The drilling waste can be further refined to ensure the waste meets a desired particle size distribution and thereafter sent for reuse by mixing the drilling waste with hot bituminous tar and thereafter using the liquids phase in roofing materials. A method of mixing the drilling waste with conventional fillers is also described to create a blended mixture of drilling waste and conventional fillers to create a new hybrid filler which is mixed with hot bituminous tar for use in roofing materials.
