Abstract
A method of paving a gravel and/or dirt roadway is provided. This method includes evaluating the roadway to determine if it is an appropriate candidate for emulsion stabilization, rotating a milling head down a roadway to break up gravel and dirt, injecting an asphalt emulsion into the broken up gravel and dirt, and mixing the emulsion with the gravel and dirt so as to form an emulsion stabilized layer. The emulsion stabilized layer is then spread and compacted to create a paved roadway. Following this, a wearing surface may be applied to the emulsion stabilized layer.
