Abstract: The Pavement Research Group at the Federal University of Espirito Santo-Brazil has been studying several
types of geomaterials for paving application. Since Brazil is one of the greatest steel producers, research efforts are
constantly made locally to develop noble use for the resulting steel by-products. This presentation will briefly
introduce the different types of steel slag aggregates (SSA) generated during the steel production. Then, it will show
some alternatives for using SSA as a sustainable geomaterial for pavement application, including case studies of soil
stabilization with KR-type slag, and evaluation of expansion effects of LD-type SSA on asphalt mixture performance.
Bio: Dr. Teixeira is a Professor of Civil Engineering in the Federal University of Espirito Santo, Brazil. Her research focuses
on infrastructure materials characterization including rheological, chemical, physical, and mechanical laboratory
experimentation, as well as computational modeling of composite materials based on microstructure multi-scale
models, viscoelasticity, and fracture mechanics. Since she obtained her Ph.D. in 2011 from the University of Nebraska-
Lincoln, she has been involved in projects sponsored by Brazilian funding agencies and industry sectors (CNPQ, FAPES,
Arcelor Mittal Steel Company, and EcoRodovias Highway Concessionaire). She is an invited member of Binder
Performance Task Group of the Brazilian Association of Technical Standards (ABNT). She has received national
recognition from Brazilian governmental agencies such as CNPq Research Productivity Scholarship and CAPES
Scholarship grant for the Improvement of Higher Education Personnel. She continuously works on regional/national
/international technical committees and on editorial services in the field of materials and civil infrastructure engineering.
