Abstract
To guarantee the requested efficiency and safety standards of the roads high quality materials must be used. Nowadays higher sensibility towards environmental issues and increasing difficulty in finding quality materials force us in search of alternative resources, able to substitute the traditional ones. Many different alternative materials were used in asphalt mixes. Variety of different materials can be used not only to substitute traditional materials but also to improve performance of built in asphalt mixtures. With alternative materials we can partly or fully substitute binder or particular stone fractions. In this work Polymethylmethacylate/Aluminium hydroxide composite dust (PMMA/ATH composite) was introduced in asphalt mixture as an additive to bitumen and filler. With laboratory tests and field trials we proved that PMMA/ATH composite as an additive to asphalt increases adhesion between stone aggregates and bitumen binders and improve the workability of asphalt mixture.
