Patent ID: 8376729

Claim:
An integrated machine for making, in a laboratory, slabs made of a controlled-compaction bituminous mix, comprising: a mould ( 4 D) configured for holding a bituminous mix ( 4 G) with a bituminous mix upper surface, the mould ( 4 D) having an upper edge and side walls, the side walls having facing surfaces separated by a first distance and that define a bituminous mix upper surface width; a cylindrical roller formed by i) two coaxial facing idle disks ( 4 A), facing surfaces of said two coaxial facing idle disks ( 4 A) being separated by a second distance, ii) a removable slab ( 4 C) located below the two coaxial facing idle disks ( 4 A) and above the mould ( 4 D), the slab ( 4 C) comprising two side projecting extensions ( 4 B), the slab having side surfaces extending from a lower surface of the two side projecting extensions ( 4 B) and a lower surface of the slab, the slab having an upper surface width greater than a width of the lower surface width by an amount equal to a width of the two side projecting extensions, the two side projecting extensions ( 4 B) being located in alignment directly below the two coaxial facing idle disks ( 4 A), the lower width of the slab ( 4 C) corresponding to the bituminous mix upper surface width within the mould ( 4 D), and iii) a central wheel ( 4 F) located between the two coaxial facing idle disks ( 4 A), wherein the second distance separating the facing surfaces of said two coaxial facing idle disks ( 4 A) is greater than the first distance of the mould's facing surfaces; and a jack ( 4 E) position to cause the central wheel ( 4 F), with the slab ( 4 C) removed, to contact the bituminous mix upper surface while said two coaxial facing idle disks ( 4 A) freely lower besides the upper edge of the mould outside exterior surfaces.
