In 1985, Dr. Richard Santi approached Leonard Velasquez of SLV Quality Concrete, an American Society of Concrete Contractors member, about replacing his asphalt parking lot with concrete pavement. Dr. Santi wanted to stop spending money on maintaining the old asphalt lot at his office. After discovering that the subgrade beneath the asphalt was very poor, Mr. Velasquez (shown here at Dr. Santi's office) suggested a new approach – overlay the asphalt with 5" of concrete, reports NRMCA Vice President, Local Paving, Don Clem. With Dr. Santi’s approval, SLV placed the first known concrete overlay over asphalt in Colorado. Neither man dreamed that the parking lot would still be in service, welcoming patients more than 30 years later - and with the added benefit that very little was spent on maintaining the parking lot during that time.
