MIT CSHub Research Offers Compelling Case to Revisit Truck Weight Restrictions

A recent study from the MIT Concrete Sustainability Hub (CSHub) reveals that increasing the allowable weight of mixer trucks could offer major environmental and cost benefits. The study examined the full life cycle impact of allowing trucks to carry up to 40 percent more weight. Results showed that heavier loads reduce fuel use, lower emissions and cut total delivery costs without increasing wear and tear on roadways. Over a 50-year span, researchers found that total system costs decreased by more than five percent, thanks to fewer trips, reduced fuel consumption and minimized pavement impact.
This research offers a compelling case for revisiting outdated weight restrictions. Fully loaded trucks could increase efficiency, reduce environmental impacts and help address the ongoing driver shortage, all while sustaining safety and protecting infrastructure.
