Effect of Additive Bitumious Binders on a New Generation of High Modulus Asphalt Mixtures

Popis výsledku v původním jazyce

Asphalt mixtures with high stiffness modulus (HMAC) are for more than 15 years an established standard for pavement structures in the Czech Republic. From the perspective of durable and long-life pavements current focus of HMAC only on the high values of stiffness is arguable. Based on this fact experimental activity in the development of next generation of high modulus asphalt mixtures was started in 2013 within the competence centre CESTI, taking into account latest trends observed e.g. in France. A set of nine selected bituminous binders was evaluated containing polymer modified binders or straight-run bitumen treated by selected additives. There was one pre-defined type of high modulus asphalt mixture with optimized grading and only the type of used binder was changed. Concurrently the bituminous binders were tested for their empirical and functional characteristics - these findings are not part of this paper. The asphalt mixtures were tested not only in terms of stiffness, but also from the perspective of their water susceptibility, behaviour in low temperature range and assessment of the complex dynamic modulus, which allowed later calculation of master curves. Results and summary of the research are presented in this paper.
