Návrh a posouzení směsi pro asfaltové vrstvy se zvýšenou odolností proti šíření trhlin (SAL) / Desing and evaluation of Bituminous Stress Absorbing Pavement Layer

Coufalík, Pavel January 2013 (has links)
This master's thesis deals with the possibility of special asphalt-rubber mixture using - Stress Absorbing Layer (SAL). In the theoretical part the SAL and test methods are described. In the practical part, several different mixtures are designed and selected mixtures were tested. Low-temperature characteristics, permanent deformations, bending tensile relaxation, stiffness modulus and fatigue properties were determined. Based on the test results the mixtures were compared and their benefit is evaluated according to Performance Pavement Design Method, the pavement structure was evaluated by using of computer programme LayEps.

Návrh speciálních asfaltových směsí SAL určených pro opravu cementobetonových krytů / Design of special asphalt mixtures SAL for the repair of cement concrete pavements

Kalfeřt, Martin January 2014 (has links)
In this thesis layer with increased resistance to crack propagation (SAL) are designed. The theoretical part describes the SAL layer, further the input materials, their production and design of various mixtures. The following is a description of the tests, which include tests of permanent deformation, crack propagation, low-temperature characteristics, test, flexural strength and relaxation. After the test results and conclusion are stated.

Posouzení asfaltového koberce drenážního a tenkého s asfaltem modifikovaným přísadou TecRoad / Evaluation of porous ashalt and acphalt conrete for very thin layers with asphalt modified by TecRoad additive

Kaška, Zdeněk January 2012 (has links)
This work is focused on the design and determination of the properties of porous asphalt and asphalt concrete for very thin layers with TecRoad addition. The water sensitivity, particle loss, stiffness, fatigue and low temperature characteristics and resistance to permanent deformation are determined for a description of mixtures properties. Subsequently, the mixtures are compared and recommendations for use in maintenance and reconstruction of roads are prepared.

Navrhování nízkohlučných asfaltových směsí / Design of low-noise asphalt mixtures

Řehulka, Martin January 2020 (has links)
The Master’s thesis is focused on low-noise asphalt mixtures in general, namely asphalt concrete for very thin layers with low noise (BBTM 8 NH) and stone mastic asphalt with low noise (SMA 8 NH). The first half of the thesis describes basic types of asphalt mixtures with low noise, requirements for raw materials (aggregates and asphalt), noise emissions and their measurement methods. The second part deals the design of BBTM 8 NH and SMA 8 NH so that they have the same voids. Subsequently, their parameters were tested. Acoustic absorption, resistence against permanent deformation and stiffness. Test methods are described and evaluated.

Recyklované kamenivo do asfaltových směsí pozemních komunikací / Recycled aggregates to asphalt mixtures of the flexible pavements

Kropáč, Pavel January 2013 (has links)
This thesis deals with the theoretical part of the creation, distribution and recycling of construction and demolition waste. Subsequently covers made from these recycled construction and demolition waste and its potential application in structural layers of the pavement. In the practical part of the thesis deals with monitoring the overall properties of nine asphalt mixtures with different proportion of recycled concrete aggregate and asphalt binder, which are designed and intended for bed asphalt pavement. The recycled concrete aggregate and asphalt are performed various laboratory tests, the results are subjected to a comparison with the relevant standards and TP 210. The conclusion is made price comparisons of asphalt mixtures.

Asfaltocementový beton / Open-graded asphalt concrete filled with a special cement grout

Hruška, Lukáš January 2012 (has links)
Aim of this thesis is the usage of the open-graded asphalt concrete filled with a special cement grout in the road structures. Thesis defines the main concrete properties and explains related legislation and norms that apply. In addition, laboratory design of asfalt mixtures and a tree kind mortal filler and possibilities of mortal filler pigmentation are dealth with. Finally, thesis evaluates the results from various laboratory tests that were performed on the specimens made from final mixtures.
