Fly Ash Use In Reconstruction Of Bituminous Roads

The purpose of this study was to develop a practical method to design local roadways using Stabilized Recycled Pavement Material (SRPM) or Stabilized Road Surface Gravel (SRSG) as the base layer and Class C fly ash as the stabilizing agent in the context of the “gravel equivalency” (GE) design methodology employed for local roads in Minnesota.  The project consisted of four major elements:  (i) laboratory testing ,  (ii) prototype pavement evaluation, (iii) field assessment of two existing roadways constructed with SRPM and SRSG, and (iv) assessment of potential impacts to ground water.
