Compressive strength of cement stabilizations containing recycled and waste materials

This study analyses the possibilities of using up to 30% reclaimed asphalt pavement as a substitute material for natural aggregate, along with fly ash replacing 20% or 40% Portland cement in stabilizations 4% and 6% binder. The Proctor test was used determine maximum dry density optimal moisture content cement-based stabilizations. compressive strength tested after 7, 28, 90 days. Parameters influencing 28-day were evaluated by full factorial design classification classes. results obtained justify utilisation waste recycled materials structures.
