The AdMaS center’s road laboratory also deals with the use of R-material – a material obtained from an old asphalt road – in the production of new asphalt mixtures in research projects. The student of the 4th year of the Faculty of Civil Engineering, Karel Spies, designed and tested a new type of asphalt mixture with a higher R-material content and asphalt content modified with rubber granulate obtained from old crushed tires. He used the AdMaS center test facility for laboratory tests. In April, the proposed asphalt mixture was used to repair potholes at the very busy intersection of Veveří and Pod Kaštany streets, resulting in a mini-test section. It should be noted that a student won with these bachelor thesis the faculty round of Student Scientific and Professional Activities (SVOČ) and advanced to the international round that will take place in Zilina.
Big thanks to Brněnské komunikace, a.s. for allowing the test section to be carried out and the assistance in performing the tests.
