Speed bumps are a great way to slow down traffic, whether it is in an apartment complex or a home owner’s association let us install speed bumps for you . Our speed bumps are made out of hot asphalt mix that is rolled and compacted to a height of approximately 2-1/2”, width of 12”-18”, and a length usually of 20’. Depending on the slope of the road, invert or crowned, an opening can be left in the center or at the edges to allow water flow.
