Influence of boundary conditions on the aging index of asphalt binders
Štohlová, Barbora ; Koudelka, Tomáš (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis deals with an influence of several boundary conditions on the aging index of various modified asphalt binders. In the thesis there is rheology and modification of asphalt binders, types of ageing (short-term, long-term) and used tests (needle penetration, softening point, complex shear modulus, phase angle, aging tests) described. In the second part there is a brief description of used materials and comparison of the test results on these materials.
