Cooler Pavements Prove Beneficial in Cooler States
Many cities are taking steps to combat the Urban Heat Island Effect. For example, Boston, a historically cooler city, has taken steps to increase the reflectivity of pavement surfaces to combat rising summer temperatures. The MIT Concrete Sustainability Hub (MIT CSHub) was interviewed on the importance of paving in concrete to forgo costly treatments in a recent piece from WBUR in Boston. The MIT CSHub notes that though there are approaches to cooling pavement such as painting or shot blasting, concrete pavements often do not require these treatments due to their inherently lighter color, which naturally keep pavement cool and provides higher reflectivity, along with other benefits such as carbon sequestration, reduced fuel consumptions and longer spans between repairs and replacement.
