• Abstract:
  TEA 21 (Transportation Equity Act 21) of 1998 allows heavy sugarcane truck loads on Louisiana interstate highways. These heavier loads are currently being ; applied to state and parish roads through trucks traveling from and to the processing plants. Generally, commercial vehicle weights and dimensions laws ; are enforced by highway agencies to ensure that excessive damage (and subsequent losses of pavement life) is not imposed on highway infrastructures like ; bridges. The axle loads and total loads of heavy trucks, which are considered primarily responsible for decreasing the service life of bridges, are signifi cant ; parameters of highway traffi c. TEA 21 is allowing sugarcane trucks to haul loads up to 100,000 lb. Because highways and bridges have traditionally been ; designed for the legal load of 80,000 lb., permitted trucks of 100,000 lb. or more decrease the expected service life of the infrastructure. During the 2009 ; regular session, the Louisiana Senate passed a Concurrent Resolution (SCR-35), which urged the Louisiana Department of Transportation and Development ; (DOTD) to conduct a pilot study on alternative truck-trailer confi gurations to support the bio-fuels industry. The senate concurrent resolution SCR-35 ; specifi cally requested that the study include vehicles hauling sugarcane biomass for alternative fuel and electricity generation. During the course of the work, ; the American Sugar Cane League indicated that their members requested that the bridge monitoring system be installed around the New Iberia area and the ; response to SCR-35 to be limited to theoretical evaluations.
