Resumen de Resilient modulus of hydraulically bound road base materials with high volume waste dust
The paper presents laboratory test results on hydraulically bound road base materials containing high volume of steel slag and blast furnace slag waste dusts compared with control mixtures. These mixtures contain higher levels of (4 mm-0.0 mm) dust compared to standard unbound road base mixtures. The combined influence of the steel slag and granulated blast furnace slag wastes content is to enhance the stiffness of the road base materials and save materials and cost during road construction. Triaxial repeated load tests were performed on the unbound and lightly bound materials to measure their resilient modulus. The test results show important improvements in the bond strength between the contents of road base materials.
This offers the prospect of using these materials in road base materials to reduce the use of primary aggregates and thus minimize the cost of road and highway construction.
