Sanborn County - S.D. Highway 37
Project Complete
Project Summary:
This eight-mile resurfacing project will reconstruct SD Highway 37 from the SD 34/SD 37 junction north to one mile south of SD Highway 224. The existing asphalt surfacing will be removed, shoulder edge drains will be installed, and the old concrete pavement below the asphalt will be rubblized before a total of 4” of asphalt concrete is paved on top. Traffic will be routed to the southbound lanes while the northbound lanes are constructed, then switched to complete the same process to construct the southbound lanes. Traffic widths will be limited to 12’ for safe travel through the project.

Project Photos:
The pictured machine is a resonant breaker that is rubblizing the existing concrete pavement. This results in chunks of concrete that interlock together almost like a puzzle, which will provide a strong base layer for our asphalt pavement that we will place on top. If we were to do nothing to the existing concrete, we would end up with a crack in the asphalt every 20’ where the existing concrete has a joint.
The head of the breaker only moves ¾” up and down, but it strikes the pavement with 2000 lb of force 44 times per second. It travels down the road around 5 mph and makes several passes in each lane to create a consistent rubblized concrete.
