Rumblestrips are a proven safety measure used to warn motorists they’ve drifted outside of their travel lane. As a result, they’re becoming more and more common as an integral part of highway design.
Trench milling is a process we use for widening rural road edges to improve safety. We’ve recently built new machines for trench milling, able to cut 1 to 4-foot wide trenches. Milled materials can be hauled off or laid along the shoulder.
Curbline edge milling preps city streets for overlays so the overlay will be flush with gutters.
Micro milling, or fine milling, is a CP process that uses a cutting drum equipped with additional cutting teeth in order to produce a much finer textured surface. Micro Milling’s primary application is to improve ride-ability and/or uniformity of the surface prior to the surface course application. It is also used to correct some minor pavement distresses by removing a very thin layer of existing pavement or to remove pavement markings due to changing traffic flows or reconstruction activities.
As mentioned above, the primary benefit of rumblestrips in general is safety. The ground materials that come from grinding rumblestrips can also be recycled and used in future road repairing projects.
Grinding the rumblestrips into the asphalt rather than rolling in the indentations is advantageous as well because it can be done at any time, as a part of the original design OR can be added to existing asphalt or concrete shoulders.
