Comparative Analysis of Modelling of Reinforced Embankment Face
Fryš, František ; Glisníková, Věra (referee) ; Boštík, Jiří (advisor)
The thesis deals with numerical modeling of reinforced earth wall. The first part of the thesis characterizes and describes these constructions in general and also describes variations of their faces. In the next part the modeling of basic reinforced earth wall construction elements in Plaxis 2D is described. Subsequently the real reinforced earth wall is modeled and some variations of face-modeling are compared.

Asphalt layers with reinforcing glass-fiber geogrids
Sachr, Jiří ; Bohuš,, Štěpán (referee) ; Dašek, Ondřej (advisor)
This diploma thesis deals with the use of glass fiber geogrids and geocomposites in road construction. The reinforcement elements are inserted between the wearing and binder asphalt layer. This diploma thesis summarizes the knowledge connected with reinforcing of asphalt roads using glass fiber. It examines the effect of reinforcing fiberglass elements on the resistance of asphalt layers loaded with traffic. At the same time, it deals with the application of a various amount of tack coat and subsequent behavior of the asphalt layers. In this work, laboratory tests of bond strength between layers on cores and four-point bending were performed.

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.
