OPTIMIZED ROAD CULVERTS MADE OF HDPE

Plastics pipes have got a market share of about 75% of new sewerage installations, the main assets being high strength, superior chemical resistance and easy handling. Results from Norway, Sweden and Finland show that they are good performers also as culverts for road building. The main drawbacks with conventional materials, concrete and corrugated steel, are due to increasing acidification of the soil, which causes severe corrosion or cracks caused by soil settlement. The toughness and the rapid relaxation properties make high density polyethylene (hdpe) an ideal material for use as road culverts. Light weight corrugated hdpe pipes with smooth bore have shown to be an economical and durable construction. The main quality requirements for such pipes are: controlled buckling behaviour and sufficient elongation at break. (TRRL)
