Porous Pavement, Widespread Use Awaits Cleaning Machines
“It works about 50 percent of the time,” says David Drullinger, an environmental quality professional with the Michigan Department of Environmental Quality. He explains that dirt, sand and other debris get stuck inside the pavement; for it to be effective again, it must be cleaned. More machines capable of unclogging these road surfaces are needed before widespread installation is viable.
As more contractors gain experience working with the new material, the more effective it may become. Several communities in Michigan already are adopting the use of porous pavement for its benefits.
