Come See Us At World of Asphalt!!
Willow Designs Notch-Wedge Safety systems build the "notched wedge joint" or "Michigan joint" that many states require for their longitudinal joint construction of asphalt hig:hways. These systems are also capable of building the "safety wedge" that the FHA recently mandated on federally funded projects.
