Resistance of asphalt binder and asphalt mixture against deformation
Dubšíková, Karolína ; Coufalík, Pavel (referee) ; Dašek, Ondřej (advisor)
Subject of this bachelor´s thesis is to describe laboratory properties of asphalt binders in relation to permanent deformation. The principle and procedure of empirical tests needle penetration and softening point will be explained in the theoretical part. The principle and procedure of MSCR test will be also described. The properties of four asphalt binders will be evaluated in practical part. These binders will be used for production of asphalt mixtures, which will be subjected to wheel tracking test and their results will be compared.
Adhesion of the materials for the horizontal marking
Šašinková, Daniela ; Dašek, Ondřej (referee) ; Varaus, Michal (advisor)
The presented bachelor thesis deals with the adhesion of materials for horizontal road marking in the case of renewal of marking and two-phase marking. Within the work specified parameters were measured and evaluated. The theoretical part describes the initial situation and is followed by the general characteristic of the horizontal road marking. Further, there are also described individual tests performed on horizontal road marking carried out within the presented bachelor thesis. The practical part deals with the preparation, production and description of the samples that have been used for this work. The evaluation of the measurements carried out on all testing samples of the marking follows. All evaluations are based on test results and photo documentation.
Asphalt mixtures with high resistance against cracks
Stromecký, Roman ; Šperka, Pavel (referee) ; Dašek, Ondřej (advisor)
In this bachelor's thesis were suggested two kinds of asphalt mixtures. The first one contains conventional asphalt binder and the second one Crumb Rubber modified Bitumen. The aim of this thesis is a comparison of stiffness and fatigue characteristics of these two mixtures by two-point bending test on truncated wedges. There will be also an evaluation of the impact of an asphalt addition of the Crumb Rubber modified Bitumen in one of these mixtures.
Dynamic viscosity of asphalt binders
Broďák, Marek ; Coufalík, Pavel (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis describes a laboratory characteristics of bituminous binders. The principle, procedure of meansurment and comparison of test results of dynamic viscosity, needle penetration and softening point by ring and ball method will be described. The tests will be performed on samples of the bituminous binders with different degree of modification.
PmB - Polymer modified bitumens
Venclíková, Michaela ; Dašek, Ondřej (referee) ; Hýzl, Petr (advisor)
In this bachelor thesis, there are described modified bitumens. The issue of modified bitumens will be explained in the theoretical part. In the practical part, it will be prepared set of modified bituminous binders with different degree of modification. Basic empirical testing and functional testing will be determined. The aim of thesis is to find the optimal source of unmodified bitumen for modification.
Usage of of common reclaimed asphalt in asphalt mixtures
Přívara, Jakub ; Coufalíková, Iva (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis is focused on adding of RAP (reclaimed asphalt pavement) to the wearing asphalt courses flexible pavements. Specifically it is SMA 11S asphalt mixture. The theoretical part describes issues of ecology and recycling. The practical part deals with bitumen recovery from SMA mixtures with different added ratios of RAP and assessment of basic empirical and functional tests on the bituminous binder. The verification of properities of modified bituminous binder used in this quality SMA mixtures is also introduced.
Force ductility of asphalt binders
Smolka, Zdeněk ; Coufalík, Pavel (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis describes a laboratory characteristics of bituminous binders. There will be described the principle and results of laboratory tests, needle penetration, softening point by ring and ball and force ductility. The tests will be performed on samples of the bituminous binders with different degrees of modification.
The quality of the fill crushed aggregate to the pavements
Surá, Kateřina ; Dašek, Ondřej (referee) ; Stehlík, Dušan (advisor)
The thesis deals with the quality monitoring of fine particle aggregates used in the road construction mixtures and in the base layers of roads. In the laboratory of Institute of road structures VUT Brno was made an evaluation of the six test samples of fine and coarse aggregates to determinate a proportion of fine-grained aggregates, the limits of fluidity and shape index.
The influence of bitumen content on properties of asphalt mixture with CRmB
Sychra, Martin ; Frýbort, David (referee) ; Dašek, Ondřej (advisor)
The asphalt mixture BBTM 5 A with crumb rubber modified bitumen (CRmB) is designed and produced in the diploma thesis. The influence of CRmB content on low temperature properties, stiffness and fatigue of asphalt mixture BBTM 5 A is determined. The influence of asphalt mixture ageing simulation on change of low temperature properties is also evaluated.
