Reducing Damage to Low Volume Asphalt-Surfaced Roads, and Improving Local Economies: Update on Variable Tire Pressure Project

摘要

Spring thaw adversely affects both pavement life and local economies throughout the northern United States and Canada. Each year significant damage is done to bituminous-surfaced low volume roads from trafficking during thaw-weakened periodes. To prevent higher maintenance and reconstruction costs, many road agencies impose load restrictions limiting loads or closing low volume roads to trucks during these damage-susceptible periods. Companies whose livelihood depends on trucking can suffer economic losses while waiting for thawing roads to recover, and for load restriction signs to be removed.
