Optimal waste cooking oil dosage in blends containing aged binder
|dc.description.abstract||This paper focuses on the influence of Waste Cooking Oil (WCO), as an alternative recycling agent, on physical and rheological properties of blends containing aged binder recovered from Reclaimed Asphalt Pavement (RAP). The objective is to determine the WCO dose that would allow the blends to achieve the same characteristics as the Virgin Binder (VB) in terms of penetration, softening point, viscosity and rheological properties. In order to achieve this, the RAP binder (RAPB) is blended with the VB (penetration grade 50/70) in three different proportions, 15%, 30% and 45% of the total binder mass. Three different doses of WCO are added in blends with 30% and 45% RAPB, while no WCO was added in the blend with 15% RAPB. Results show that the optimal WCO dose is lower when tests producing lower strains in samples (Dynamic Shear Rheometer and penetration) are used, compared to tests producing higher strains (viscosity).||en|
