Design of the asphalt mixture using Friction After Polishing parameter
Original language description
The paper presents results of the research project which aims to design and test wearing courses containing mixtures of aggregates with different resistance to polishing and improve quality and lifespan of skid resistance properties of pavements built in areas where aggregate resistant against polishing is not available. Within the research project, five different SMA mixtures were produced, each containing a different ratio of aggregate from various sources (basalt and greywacke). The test specimens made of these asphalt mixtures were tested according to EN 12697-49: the laboratory equipment simulates the traffic load and thus allows the prediction of the development of the friction coefficient with time. Based on the results of the laboratory measurements, asphalt mixtures were selected for the production of three test sections in the area of the asphalt plant and one test section on the trafficked road. The paper compares the results of FAP (Friction After Polishing) measured in the laboratory and
