ENGINEERING AND ENVIRONMENTAL ASPECTS OF CUTBACK ASPHALT (MC-70) STABILIZATION OF SWELLING AND COLLAPSIBLE SOILS

The basic objective of this research was to investigate the effectiveness of Cutback Asphalt (MC-70) as a soil stabilizing agent. For this purpose, four different soils from Northern Jordan, which exhibit certain engineering problems, such as swelling and collapsibility, were selected. Both natural and Cutback Asphalt (MC-70) treated soils were subjected to similar laboratory tests to observe the influence of Cutback Asphalt (MC-70) on swelling and collapse potential. The test results showed that Cutback Asphalt (MC-70) is effective in stabilizing the tested soils. Upon mixing with soils, bituminous materials act as a binding agent between soil particles. Additionally, test results showed that Cutback Asphalt (MC-70) percentages in excess of 7 percent do not show a substantial reduction in swelling and collapsibility potentials. A general comparison of the effectiveness and economic feasibility of Cutback Asphalt (MC-70) to lime and cement, as stabilizing agents for reduction of swell potential of soils containing a high percentage of fines (e.g., Irbid Soil), showed that Cutback Asphalt (MC-70) causes higher reduction in swell potential than cement and a lower reduction than lime.
