Tlačna čvrstoća cementnih stabilizacija koje sadržavaju reciklirani i otpadni materijal (Compressive strength of cement stabilizations containing recycled and waste materials)

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