Abstract:

The aim of my bachelor thesis is to design asphalt mixture with a higher lifetime (mixture of type VMT 16) and its subsequent assessment by selected functional tests. VMT blends are used for load and underlayer layers of roads with higher transport loads. The main idea of this bachelor thesis is the design of an asphalt mixture consisting of natural aggregates, recycled asphalt mixtures and crumb rubber modified bitumen, yet retaining good road-holding properties. The use of recyclable bituminous mixtures will allow the recycling of bent or milled asphalt layers, which is currently high in surplus, and will allow the overall cost of building new high-quality asphalt layers to be reduced. The bachelor thesis describes the empirical and functional tests performed, according to which the resulting asphalt mixture was designed, and the results compared with the TP151 Asphalt mixture with high modulus of stiffness (VMT).

Keywords:

High modulus asphalt mixtures, reclaimed asphalt pavement (RAP), bitumen, crumb rubber modified bitumen, stiffness, fatigue, frost cracks.
