Abstract
Cold recycled material (CRM) is one of the most innovative road materials. CRM offers many advantages compared to Hot Asphalt Mix (HMA) including reducing the construction cost and energy consumption as well as offering a good ability to resist reflective cracking. CRM is composed of Reclaimed Asphalt (RA) and bitumen emulsion. As an additional co-binder, a small amount of cement is used. But the use of cement could show signs of an adverse impact that makes the CRM sensitive to cracking as it is subjected to heavy traffic load, resulting in reflective cracking. This paper presents a study on the fracture-fatigue behavior of CRM modified by byproduct fillers aiming at improved CRM mixture. CIT-CY fatigue and SCB fracture tests test were conducted on the mixture and mortar respectively. Results show that CRM materials with specific filler showed balanced fatigue and fracture resistance.
