Abstract:

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.

Keywords:

Reinforcement element, glass fiber, geogrid, geocomposite, tack coat, asphalt reinforcement, asphalt mixture, road defects, refraction cracks, fatigue cracks, freezing cracks, tension, bonding of layers, four point bending
