HIGH TEMPERATURES CAUSING PAVEMENT BLOWUPS
(AMES) Motorists traveling in Iowa should be aware that the mercury might not be the only thing to rise during the sweltering summer heat. Pavement blowups occur when thermal expansion forces the pavement to buckle and shatter. A number of such incidents have been occurring this week.
Unlike scheduled maintenance, pavement blowups occur spontaneously and motorists receive no advance warning. Once a blowup is reported, it takes time to erect a work zone and notify the public.
The Iowa DOT urges motorists to pay special attention to pavement surfaces when driving during afternoons with 90-degree or hotter temperatures. Use caution and reduce your speed when approaching broken pavement areas.
Motorists who witness a pavement blowup are asked to contact the nearest law enforcement agency to ensure traffic is routed around the blowup until work zone signage and repair crews are on the scene.
