Asphalt concrete for very thin layers
Kubánek, Ondřej ; Frýbort, David (referee) ; Hýzl, Petr (advisor)
The aim of bachelor thesis is to gain experience with the design mixtures of asphalt concrete for very thin layers. Familiarizing with the properties of these mixtures, as porosity, water resistance and resistance to permanent deformation. Comparing detected parameters with the requirements of standard EN 13108-2 and its National Annex.
Swedish and US AR mixture design comparison
Puda, Adam ; Frýbort, David (referee) ; Kudrna, Jan (advisor)
This master's theseis deals with comparison of two design concepts for producting asphalt mixture with CRmB. These design concepts are from Sweden and USA. The theoretical part sets parameters for design of asphalt mixture and chracteristic tests. In the practical part test speciements of design asphatl mixture undergo performace tests that simulate climate and traffic load. Results are compared to mathematical model used in program LayEps.
Design of SAL asphalt mixtures for rehabilitation of concrete pavements
Vlk, Radomír ; Hegr, Zdeněk (referee) ; Varaus, Michal (advisor)
This master's thesis describes how to use the asphalt layer called Stress Absorbing Layer (SAL) and comparises it with other types of SAL with different types of asphalt binders. In the first theoretical part is SAL generally described. In the second part is SAL practically tested and described.
Usage of recycled materials to asphalt mixtures
Zítka, Patrik ; Kašpar, Jiří (referee) ; Hýzl, Petr (advisor)
This thesis deals with the R-material use in asphalt mixtures. In the theoretical part, different kinds of flexible pavement recycling and ways of adding R-material into asphalt mixtures are discussed. The practical part deals with asphalt layers design and manufacture, specifically for binder course ACL 16+. R-material content in the blends is 0%, 20%, 25% and 30%. EVOTHERM MA3 rejuvenator is used as additive for softening of R-material. Various mixtures are compared based on tests - resistance to permanent deformation, resistance to the effects of water and low temperature properties.
Design of special asphalt mixtures SAL for the repair of cement concrete pavements
Kalfeřt, Martin ; Špaček, Petr (referee) ; Varaus, Michal (advisor)
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.
The segragation of mixtures to pavement
Trávníček, Dušan ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The work deals with the examination of repression and segregation in asphalt mixtures. The theoretical part is monitoring the current situation about the problem of segregation, which mainly refers to the practical adjustments during laying „risking“ asphalt mixtures on the formation of segregated places in the shelter layers of roads. The practical parts of the thesis are summarised measurements on six samples of the most commonly used asphalt mixtures to determine the segregation depending on the selected parameters. The work is describing and valorising a test for determining segregation according to ČSN EN 12697-15.
The issue of increasing the proportion of reclaimed asphalt in asphalt mixtures
Urbanec, Luboš ; Mondschein,, Petr (referee) ; Hýzl, Petr (advisor)
The subject of this Ing. thesis is asphalt mixture with increasing RAP (Reclaimed Asphalt Pavement). The theoretical part defines the terms of recycling and RAP and types of recycling. The practical part is devoted to the production and testing of asphalt mixtures with different volume RAP. The proposed asphalt mixture is asphalt concrete for base layer ACP22 +. Content of RAP in mixtures is 0%, 30%, 50% and 70%. As a special additive to soften the asphalt from RAP is used ingredient STORFLUX. For each mixture are established modulus stiffness of asphalt mixture and determined fatigue characteristics of asphalt mixture. The identified properties are compared for the different representation of RAP.
Desing and evaluation of Bituminous Stress Absorbing Pavement Layer
Coufalík, Pavel ; Špaček, Petr (referee) ; Kudrna, Jan (advisor)
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.
Recycled aggregates to asphalt mixtures of the flexible pavements
Kropáč, Pavel ; Zdřálek, Petr (referee) ; Stehlík, Dušan (advisor)
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.
Design and evaluation of asphalt rubber mixture for pavement binder course
Musílek, Lukáš ; Telecký, Jiří (referee) ; Kudrna, Jan (advisor)
The design of asphalt concrete for binder courses with high-viscosity asphalt rubber and low-viscosity asphalt rubber is carried out in the diploma thesis. Selected performance tests (low temperature characteristics, stiffness and fatigue) and water sensitivity are performed for these mixtures. Results are compared each other.
