Construction and Interim Performance Report of Experimental Salt (NaCl) Stabilization of Plant-Mixed, Dense Graded Aggregate

For some time the Department has been interested in building-up and retaining thicknesses of granular base course on rural roads through the use of various stabilizing additives and(or) the use of light asphalt seals or surfacings (1, 2, 3, 4, 5, 6). These efforts more or less recognize that the stage construction concept is frustrated by weather and traffic erosion of unbound and exposed granular base material. Thus, the motive in experimenting with and in utilizing these treatments is to find economical and effective means by which a granular base can be built and retained until such time that a higher type bituminous surface can be constructed upon it
