Sustainability | Free Full-Text | Fatigue and Thermal Cracking of Hot and Warm Bituminous Mixtures with Different RAP Contents


This paper presents outcomes of laboratory assessments on scorching and heat bituminous mixtures produced with Reclaimed Asphalt Pavement (RAP). Components have been used to provide heat bituminous mixtures. Fatigue behaviour and thermomechanical behaviour at low temperature have been investigated. Fatigue was studied by analysing the stress/compression fatigue check outcomes. 4 totally different failure standards have been used with the intention to consider fatigue life. The low temperature behaviour of the supplies was characterised utilizing the Thermal Stress Restrained Specimen Take a look at (TSRST). For every materials, three replicates have been carried out. The experimental gadget was improved in order that radial strains in two instructions might be measured through the assessments. Tri-dimensional behaviour may thus be investigated. The outcomes of each assessments have been analysed and the affect of the void content material, RAP content material, kind of components and manufacturing course of was evaluated. The outcomes present that RAP addition and heat bituminous mixtures might be mixed to acquire mixtures with performances similar to classical scorching mixtures.
