Nízkoteplotní vlastnosti asfaltových pojiv a směsí / Low temperature properties of asphalt binders and mixtures

Veselý, Petr Unknown Date (has links)
Today’s society is highly reliable on a working road infrastructure, which is because of collective efforts already built in terms of main net of roadways, and the attention is now paid to its service life primarily from a point of view of a climate change which is causing more frequent temperature extremes. This thesis sets its goal to perform basic tests for bitumen, especially ones dealing with low temperature properties, on types of bitumen usually used in out day to day world and asphalt mixtures made with those types of bitumen. The theoretical part talks about the basic definition of bitumen and studies performed on the similar issue. Practical part of the thesis is focused on performing the tests of bitumen and asphalt, which include but are not limited to, penetration test, softening point test, critical temperature detected by method by Fraasse and the bending beam rheometer and the test to set critical temperature of asphalt by using TSRST. At the end of the thesis the evaluation of results and its mutual correlation is performed.

Hrubozrnné asfaltové směsi / Coarse-grained asphalt mixtures

Brida, Peter January 2022 (has links)
The diploma thesis is focused on the comparison of the influence coarse-grained aggragate on the properties af asphalt concrete. The theoretical part describes issue of production and usage of asphalt mixtures. The practical part evaluates multiple types of asphalt mixtures and describing their properties. Stiffness by a two-point bending test, a wheel tracking test and low-temperature cracking and properties by uniaxial tension test were used to evaluate the properties of the mixtures.

Inovativní asfaltové směsi pro obrusné vrstvy s použitím vyššího množství R-materiálu / Innovative Asphalt Mixtures for Wearing Course with a Higher Content of Reclaimed Asphalt Pavement

Spies, Karel Unknown Date (has links)
This master's thesis deals with the design of two asphalt mixtures for a wearing course containing 35 % R-material. The asphalt mixtures use a soft bitumen modified with crumb rubber (CRMB) or the unmodified soft binder itself with a penetration grade of 70/100. The work verifies the effect of crumb rubber as a bitumen modifier on the properties of the asphalt mixture with reclaimed asphalt pavement (RAP). At the same time, the work deals with the possibility of using higher amounts of reclaimed asphalt pavement only in combination with a softer binder without the use of rejuvenating additives. The properties of asphalt binders and mixtures are verified using suitable functional tests. Furthermore, the proposed mixtures and their results are compared from various perspectives. At the same time, the thesis in the theoretical part deals with the dosing of a reclaimed asphalt pavement into the asphalt mixture and describes the handling and use of reclaimed asphalt pavement in the Czech Republic and abroad
