Geotechnical Properties of Soil Stabilized with Blended Binders for Sustainable Road Base Applications

This study aimed at evaluating the effect of blended binders on stabilization clayey soils intended for use as road and pavement materials in selected regions Sweden. The potential containing five stabilizers (cement, bio fly ash, energy slag lime) was investigated using laboratory tests statistical analysis. Soil samples were compacted Swedish Standards UCS. specimens stabilized with mixtures various ratios binders. effects changed ratio soil strength analyzed velocities seismic P-waves penetrating tested day 14 experiment. difference surface response indicated variations evaluated specimens. We combination to improve soil. mix slag/lime or slag/cement accelerated hardening process gave durable product. noted that pure lime (burnt quenched) is best suited fine-grained clay minerals. Slag used this had a very finely ground structure hydraulic properties (hardens under water) without activation. Therefore, has too slow curing it be practical real projects roads. performance demonstrated by consisted lime/fly ash/cement which considerably improved geotechnical workability increased its strength. conclude bearing capacities construction can significantly mixed binders, compared (cement).
