| Abstract: | In this study the properties
of hot bituminous mix containing ferrochromium slag with neat and
styrene-butadiene-styrene modified binders have been investigated. The
ferrochromium slag is used as coarse aggregate and total aggregate. Three
different binders, B 50/70, B 160/220 and B
160/220+3% SBS, are used in mixtures. The physical and mechanical properties of
polymer modified binders and binder-aggregate mixes are evaluated in terms of
their fundamental engineering properties such as dynamic shear rheometer (DSR),
rotational viscometer (RV) for binders,
Marshall stability, indirect tensile stiffness modulus, tensile strength and
moisture susceptibility for mixtures. It has been concluded through the
laboratory tests that using ferrochromium slag as coarse aggregate provided satisfactory
results. The usage of ferrochromium slag as total aggregate does not exhibit
good performance in terms of stability and stiffness modulus. However, the
mixtures prepared entirely with ferrochromium slag showed good resistance to
moisture damage. It is found that in spite of the similarity between high
temperature performance grades of B 50/70 and B 160/220+3% SBS, the mechanical
properties of the mixtures prepared with these binders do not show the same
performance. |
