One form of street maintenance is sometimes referred to as “asphalt overlay”. Once asphalt has been laid, it can be driven on almost immediately. However, drivers are asked to watch for and respect the detour requests of flaggers as street workers put the final touches on the road, such as smoothing it out with heavy road rollers.
“The benefits of asphalt are durability, cost effectiveness, smoothness and the ability to install it relatively quickly,” said Dave Nichols, public works director for the City of Columbia. “It is also a recyclable asset.”
