Any material not intentionally attached or bonded to the shoulder pavement surface which is not required for the operation or maintenance of the highway including, but not limited to, any loose aggregates, any undesirable grasses and other accumulated material or foreign matter, shall be removed by sweeping, cleaning, vacuuming, shoveling, and disposal of the material. These specifications and special provisions are end–result oriented. Although the main purpose of this contract is to accomplish road-sweeping operations on State roadways, the Contractor will encounter objects larger than what a sweeper can remove. Objects such as, but not limited to tires, tire parts, hub caps, large stones, boxes, tree limbs/bark, wood, cable, large silt and grass combination etc. may be encountered by the Contractor. At such time, the Contractor shall remove these objects by hand if sweeper operations are unsuccessful.
