Asphalt Pulverizing

What is pulverization? Pulverizing is a process that grinds up existing surface layers right in place, blending the asphalt layers with any sub-layers, essentially creating a new paving mix using all the old materials. No pavement is hauled away, saving costs on excavating and trucking, and rarely does new material have to be brought in (though ...
