Abstract: A recycled tire rubber barrier modular system comprising an elongated core of recycled rubber, polymer adhesive, and hardener; a base coupled to the elongated core; and two concave elongate walls which may be coupled to the elongated core and to the base. Additionally, two oppositely positioned sidewalls each of which may be coupled to the elongated core and to the base, and each sidewall may be joined to the concave elongate wall. The barrier system may further have a lateral hooking arm coupled to the elongated core above the concave elongate wall which is coupled to both sidewalls.
