Abstract: A method of making a polymer-binder composite, and the composite thus created. The method employs a high shear device that mixes together polymer with binder, and optionally with additive. The mixing is accomplished in less than one hour, less than 30 minutes or less than 3 minutes, and done at high shear rates. The shear conditions are defined by scalar shear quantity greater than 250, 1,000 or 1,500, resident time of greater than 0.05, 0.10 or 0.20 seconds, and energy utilized per unit mass of greater than 0.05, 0.10 or 0.20 kW/kg. The composite thus produced can be made with a high percentage of polymers. It can be cooled and cut into pellets that are dry and stable at normal temperatures and which can be stored or transported without heating to secondary mixing locations. The composite pellets are quickly soluble in the additional binder.

The mixing is accomplished in less than one hour, less than 30 minutes or less than 3 minutes, and done at high shear rates. The shear conditions are defined by scalar shear quantity greater than 10,000, 20,000 or 25,000, resident time of greater than 0.5, 1.0 or 5 seconds, and energy utilized per unit mass of greater than 0.5, 1.0 or 2.0 KW/KG. The composite thus produced can be made with a high percentage of polymers. It can be cooled and cut into pellets that are dry and stable at normal temperatures and which can be stored or transported without heating to secondary mixing locations. The composite pellets are quickly soluble in the additional binder.

Abstract: A roadway paving system for chipsealing a roadway surface comprising a novel roadway paving vehicle and a novel supply truck is provided. The roadway paving vehicle comprises an asphalt binder material dispensing system and an aggregate material dispensing system. The asphalt binder material dispensing system includes an asphalt tank and a sprayer that sprays a first layer of the asphalt binder material over the roadway surface. The aggregate material dispensing system comprises an aggregate hopper and conveyor mechanism that discharges a second layer of aggregate material over the roadway surface. No wheels run over a freshly laid surface. Supply trucks are linked to the roadway paving vehicle to refill the roadway paving vehicle on a continuous basis without the need of stopping the vehicle.
