MoDOT can actually reuse asphalt directly in place by heating it, processing it on the road and relaying it. The process is called "Hot In-Place Recycling" and it saves Missourians millions of dollars every year. Here's how it works.

• First the surface of the road is heated.  It is processed using specialized equipment that scarifies it on the road while mixing in a rejuvenating agent.
• Next, the recycled asphalt is spread back across the lane.
• Then the refurbished material is ready for a new asphalt overlay without leaving the site.
