Road maintenance treatments like slurry seal, chip seal, and latex micro-surfacing were all created to meet the different budgets, requirements and conditions that determine how best to preserve and renew asphalt roads. The economic value of liquid asphalt road maintenance treatments is well-established and fairly well-known. More recently, independent studies are showing how various pavement preservation treatments increase the safety of our roads too. In fact, sometimes preservation treatments are put on particular stretches of roads to reduce the number of accidents in that specific area. See below for some surprising facts about the economics and safety of surface treatments.
