20140260525 | APPARATUS, METHODS AND SYSTEMS FOR MEASUREMENT OF CHIP LOSS DURING ASPHALT SURFACE TREATMENT CONSTRUCTION AND DESIGN - A post-road surface maintenance field test device includes a frame, a plurality of wheels connected to the frame, a rotatable brush held at least partially by or within the frame, a drive mechanism configured to rotate the brush, and a collection member. The collection member is held at least partially by or within the frame and resides adjacent the rotatable brush. In operation, as the device is conveyed over a road surface, the drive mechanism rotates the brush and the brush engages loose aggregates and/or aggregates that are weakly bound to a bonding medium and urges the engaged aggregates into the collection member. | 09-18-2014 |
