From the first day a new road is put into service it begins to deteriorate. How fast this happens, obviously depends mainly on usage, but other factors such as how and when it was maintained play a very important role with any road. For graveled surfacing, most believe the surface just wears out, but there are only three places the valuable surface aggregate could go; 1) compacted deeper into the sub-grade, 2) ground into dust and blown off, or 3) side-cast from the roadway from improper maintenance or snow removal.

After years of secondary road maintenance Roadtech, Inc. has developed a cost-effective way to recover this valuable side-cast material and return it to the road surface. The Linear Screening process developed by Roadtech Inc. changes the way material is screened. Instead of bringing the material to the screen, we bring the screen to the material. In the right application, this can greatly reduce the cost of aggregate replacement. Now, we are able to recover side-cast material, though polluted with oversized rocks, and screen out the usable material for the running surface. The larger rock can be side cast or crushed with our Linear crushing equipment for additional wear course.
