Asphalt Layers using Fibreglass Composite Materials
Sadil, Dominik ; Hýzl, Petr (referee) ; Šperka, Pavel (advisor)
The diploma thesis deals with using of reinforcing composite materials in asphalt layers. These geosynthetic materials are in road construction used especially to reduce spreading cracks and extend the service life of the construction. As par of this work, test specimens of different types of asphalt layers were produced. These samples were subjected to laboratory testing, where the results of different reinforced asphalt slabs were compared. Within the diploma thesis primarily deals with the testing of the shear bond strength between asphalt layers in order to determine what are the other influencing factors of the test. Another part of the thesis is the 4-point bending test, during which a special technology in the form of a DIC camera was used to monitor the behavior of the asphalt layer over time.

The use of glassgrids in asphalt pavement structure
Sadil, Dominik ; Šperka, Pavel (referee) ; Kudrna, Jan (advisor)
The bachelor thesis deals with the use of fiberglass grids in asphalt layers. These materials are used as reinforcement materials in road construction primarily to partially elimination or delay the formation of cracks in the roadway and to transfer the tensile loads that are distributed to the sub-layers. The bachelor thesis tests the properties asphalt layers reinforced by geogrids by using selected functional tests and also was monitored their behavior between asphalt layers. At the same time, the thesis determines whether these functional tests are practically applicable for asphalt layers with fiberglass grids.

Re-using Asphalt Reinforcement Geogrids in Asphalt Mixtures
Provazník, Petr ; Sadil, Dominik (referee) ; Šperka, Pavel (advisor)
The bachelor thesis deals with the topic of re-using reinforcing fiberglass grid which are applied to asphalt layers. The theoretical part describes the general properties of reinforcing materials which includes reinforcement grids and also reinforcing dispersed fibres. There is also a characterization of reclaimed asphalt pavement and its current use. The practical part investigates the properties of reclaimed asphalt pavement which contains milled fiberglass grids. For this purpose several sets of test specimens were made of reclaimed asphalt pavement with proportion of milled fiberglass geogrids. The individual properties of the samples were compared with the initial set which did not contain milled grids. Another comparative sample was R-material to which were added Forta-Fi reinforcing fibers. Functional tests ITS and stiffness were performed on the made samples.
