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.
Coarse-grained asphalt concretes
Škorík, Michal ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
This diploma thesis deals with the design of coarse-grained asphalt concrete for base courses with aggregates up to 32 mm in size. The theoretical part describes current issues related to the shortage of natural aggregate in the Czech Republic and introduces the reader to the knowledge of coarse-grained asphalt mixtures used in the Czech Republic and abroad. The practical part focuses on the design of asphalt mixtures for base courses AC 32 50/70. It further describes in detail the process of laboratory production of the asphalt mixture and individual functional and empirical tests. In the last part parameters as modulus of stiffness, resistance to low temperatures and resistance to permanent deformations are evaluated.
Issue of asphalt mixtures with coarse-grained aggregates
Koblížek, Ondřej ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The diploma thesis deals with the design of asphalt mixture of asphalt concrete type for base courses with maximum aggregate grain up to 32 mm and investigates the influence of the amount of asphalt binder on the properties of this mixture. The theoretical part describes the problem of aggregate shortage in the Czech Republic and the division of aggregates into various categories. In the next part, the laboratory used tests (needle penetration determination, softening point determination, compaction degree, determination of the stiffness modulus, low temperature properties and wheel tracking) are described in detail. The practical part describes the used materials, the results of the laboratory tests, their comparison and evaluation.
Open-graded asphalt concrete filled with a special cement grout
Hruška, Lukáš ; Mondschein,, Petr (referee) ; Hýzl, Petr (advisor)
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.
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.
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.
