A mixture formed from desired proportions of recycled asphalt shingle and recycled asphalt pavement is disclosed. The methods of molding the mixture into paving blocks, which exhibit properties of high compressive strength and low water absorption, are described. The paving blocks may be used to construct roads, parking lots, driveways, etc.

The paving blocks may be used to construct roads, parking lots, driveways, etc. A heated auger system for transferring the mixture to a molding system. The heated auger system can include concentric bodies to form separate concentric chambers, with one chamber receiving a heated fluid therethrough, and the other chamber for transporting the mixture through the auger system for heating by the heated fluid.

A high-friction road patch may comprise an aggregate capable of providing sufficient friction between a road surface and vehicle wheel. In some embodiments, the patch may comprise a waterproof, asphalt overlay with a first layer of cured bitumen and calcined bauxite aggregate particles, a second layer of viscous bitumen and a reinforcement component, and a binder layer for bonding the overlay with the road surface. The resulting product may provide a sufficient skid resistance value in an overlay that is far less susceptible to or incapable of debonding as with prior art solutions.
