In this study, in order to investigate the thermal fatigue resistance of naturally-aged asphalt concrete specimens, an experimental setup is developed. Mixture design variables, selected according the superpave method of design, include asphalt content, asphalt type, aggregate type, gradation and modification. In the course of this study, using the developed setup, thermal coefficients and thermal fatigue life of the asphalt concrete specimens are measured. Then, using the analysis of variance tests the significant mixture design variables affecting the two types of tests are identified. According to the statistical analyses, aggregate type, gradation, asphalt type and asphalt content significantly affect the thermal coefficient of asphalt concrete. The thermal fatigue resistance is significantly affected by aggregate type, asphalt content and the asphalt type. The results of this study provide a solution to minimize the thermal fatigue cracking in asphalt concrete pavements.

Investigation of low temperature cracking in asphalt concrete pavement
Qadir, Adnan; Güler, Murat; Department of Civil Engineering (2010)
In this study, low temperature cracking of asphalt concrete is investigated based on a laboratory experimental program including the design variables of aggregate type, gradation, asphalt content, binder grading, binder modification, and the experimental variables of cooling rate, and specimen size. The design of experiment is proposed according to the fractional factorial design principles to reduce the required number of test specimens. Mix designs are performed according to the Superpave mix design guide...
Development of a new testing procedure to measure thermal fatigue performance of asphalt concrete
Shabani, Reza; Güler, Murat; Department of Civil Engineering (2020-11)
In the scope of this study, a new test procedure is developed to investigate the thermal fatigue performance of asphalt concrete materials. To achieve this, test samples are compacted using different mixtures to be designed according to the Superpave mix design method. In the testing program, compacted samples are cut to produce beam specimens for thermal coefficient tests and semicircular specimens for thermal fatigue tests. Analysis of variance (ANOVA) and Multivariate analyses are both used to evaluate t...
Low temperature performance of asphalt concrete under direct tension loading
Karakaya, Yalçın; Güler, Murat; Department of Civil Engineering (2015)
Thermal cracking is one of the major distresses in asphalt pavements and has been a serious concern especially in cold regions. There are two different mechanisms for temperature cracking in the field: Low temperature cracking associated with severe temperature drops and thermal fatigue cracking in reaction to repeated temperature cycles. In this study, in order to investigate the thermal tensile properties of asphalt concrete, Direct Tension Test (DTT) is utilized in a TSRST experimental setup. Naturally-a...
Investigation of the impact of aggregate segregation on rutting resistance of asphalt concrete
Yücel, Ayhan Öner; Güler, Murat.; Department of Civil Engineering (2019)
In this study, effect of aggregate segregation on rutting resistance of asphalt concrete is investigated using laboratory compacted specimens. A procedure to determine inhomogeneity level is proposed using 2-dimensional cross section images of asphalt concrete specimens. A redistribution algorithm is developed to assess the aggregate distribution characteristics and inhomogeneity index of the cross sectional images. In order to simulate field conditions, specimens are produced in two different groups: (i) w...
The Effects of Implementing Different Ground-motionLogic-tree Frameworks on Seismic Risk Assessment
Ay, Bekir Özer (null; 2018-06-21)
This study investigates the link between probabilistic seismic hazard assessment and corresponding loss estimations by using different ground-motion logic-tree frameworks from reliable large scale seismic hazard projects as well as the logic-tree framework established in this study. The predictive models selected for these logic trees are expected to represent the center, body and range of ground-motion intensity measure estimates. Regarding with the hazard component of risk assessment, the ground motion in...
