Ohio is looking at requiring rumble strips in the center line on two lane, undivided routes. Due to the potential issues with decreasing the durability around longitudinal joints, which typically have a lower density than the mat, we created a specification to address preparation of these joints: either mill a minimum of 3" off the cold joint or use ODOT SS-872 Void Reducing Asphalt Membrane (VRAM).
