Abstract: Speed bumps for mounting across roadway lanes to encourage vehicle drivers to slow down are formed of laminated layers of elongated flexible rubber strips secured together to form a speed bump unit. Typical bump heights of three inches are obtained from six laminated half-inch layers. in one embodiment, layers not exceeding five inch widths cut from treads of discarded vehicle tires between opposing shoulders have a propensity to lie flatly upon a road surface, and are pyramided upwardly by a plurality of stepped layers of decreasing widths thus presenting inclined leading and trailing edges for intercepting the tires of oncoming moving vehicles. In another embodiment curved layers of tire tread strips form ingress and egress edges inclined gradually downward from an uppermost crown to the roadway surface for intercepting the oncoming moving vehicle tires.

Abstract: Flat strips cut from discarded tires are stacked and stored as bulk rubber on pallets for easy handling, transport by fork lift trucks and storage in outside compacted storage space without accumulating water where mosquitos can breed. Typically flat rectangular longitudinal tread strips are folded and stacked in a plurality of abutting stacks about five feet high for rubber-to-rubber engagement in configurations extending substantially to opposite edges of a pallet platform, thus storing about a ton of bulk rubber per pallet. The pallets then may be transported and stored in compact stacks at outside locations without accumulating water and breeding mosquitos.

Abstract: A flexible impact energy absorption resilient and flexible rubber strip accessory has an adhesive layer for affixing it to an exterior curved automobile body surface. An inexpensive preferred embodiment is formed using tire tread strips cut from the carcasses of discarded automobile tires. Thus, steel belted tires provide embedded reinforcement for absorbing higher levels of impact energy without any visible damage to the tread strip or the adjacent car body surface upon which it is affixed. This accessory has an adhesive layer for attachment to a car surface having a manually protective paper or plastic cover so that it may be retrofit upon an exterior surface of an automobile without requiring any special tools. The accessory is universally adaptable to a large range of automobile body styles.
