Being Green
 

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.

Old asphalt is heated and scrapped off the highway

 

 

 

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.


 

 

 

The recycled asphalt is then spread back across the lane
