Abstract

A crash barrier for road highways is designed to provide a progressively increasing resistance to impact, which is designed with the sturdy fabrication of creosote-treated and HDPE-coated bamboo poles. Which is weatherproof and long-lasting, highly resistive against fungal, borer, termite attacks and working on using flexibility to dissipate the kinetic energy from a collision. In one embodiment a beam (2) comprising a club of three separate poles 2(a), 2(b), 2(c) is mounted on upright posts (1) consisting of three poles 1(a), 1(b), 1(c) placed triangularly at an angle of 60° with each other with connecting elements (3, 4). The rear elements (4) are of bamboo with node and are relatively stiff while the front elements (3) are hollow tubular and therefore more easily deformed. The deformable connections are fabricated with high tension GI wire rope 7, fixed with U clamps 9, and locked with crimping locks 8.
