Described herein is a process for paving a surface with an asphalt paving material, comprising the steps of laying asphalt paving material on a surface to be paved; and combining an asphalt rejuvenator and the asphalt paving material; wherein the asphalt rejuvenator and the asphalt paving material are combined immediately before, concurrently with, or immediately after the asphalt paving material is laid on the surface to be paved. The asphalt paving material may be virgin asphalt, or it may comprise reclaimed asphalt pavement and/or recycled asphalt shingles.

Article made of conglomerate material in the form of a slab comprising an aggregate which includes granules of expanded material having a selected particle size range and defining between them inter-granular cavities containing only air and no filling material. The aggregate also includes a binder present in a controlled minimum quantity sufficient for lining the granules of expanded material. The article also comprises a lining layer integral with the aggregate. The invention also relates to a method for the production of an article made of conglomerate material.

Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. Locations of the first pattern have a first average thickness perpendicular to the slab width and the slab length, and locations of the second pattern have a second average thickness perpendicular to the slab width and the slab length that is different from the first average thickness.
