abstract
Calcium chloride is widely used for dust control on unpaved roadway surfaces, in base course stabilization, full depth reclamation and for total reconstruction of asphalt roads. Fly ash produced from coal-burning electric power plants have also been used in road construction. This paper examines the synergistic effect of calcium chloride and fly ash on compaction density and strength development of unpaved roadways. A mathematical model has been developed which provides excellent agreement with the experimental data. Based on these results, the potential of calcium chloride - fly ash treatments for typical mine road construction is discussed.
