    Part of the work is also consumed by the friction of the crushing mechanism, by the plastic deformation of the crushing contacts, and by the crushing of the aggregates. This thesis concentrates on studying how the movement pattern of the jaw crusher affects the wear of the jaw plates and the work consumed in the crushing and wear processes.

    The performance of the new generation of HMA mixture relying more on a stone-on-stone contact is greatly influenced by the properties of the aggregate blends such as gradation and strength. As a result, aggregates have a significant and direct effect on the performance of bituminous pavements and it is important to maximize the quality of aggregate to ensure the proper performance of roadways.
