In this study, correlation between rutting potential of hot asphalt mixtures and shear resistance is investigated using Gyratory Load Cell Plate Assembly (GLPA). The GLPA was developed to measure shear resistance of asphalt mixtures with the Superpave gyratory compactor. To demonstrate a possible correlation between shear resistance and rutting, unconfined triaxial repeated load tests were conducted on specimens compacted by varying gradation, asphalt content and fine aggregate angularity. Results of MnRoad field experiments were used to determine rutting test parameters, i.e. deviatoric stress, temperature and loading frequency, to approximate field conditions. Analyses were performed to investigate if a correlation exists between shear resistance and flow number which indicates mix potential for rutting. Test results indicted that expected relationships were reasonably obtained for all tests specimens. It was found that specimens with higher shear resistance resulted in larger flow numbers and hence lower permanent strains than those with lower shear resistance (A).

Site Specific Relationship for Strain Dependent Shear Modulus and Damping Using In Situ V S and High Strain Cyclic Test Results
Zehtab, Kaveh Hassan; Yılmaz, Mustafa Tolga (2016-08-18)
This study suggests a practical method for estimating site-specific strain dependent shear modulus and damping. The method uses in-situ shear wave velocity measurements and commercial cyclic laboratory tests on higher strains (i.e., 0.5% to 1%) in which the effect of disturbance is less significant. Shear modulus calculated using in-situ shear wave velocity and at higher cyclic shear strain, is used for building a hyperbolic relationship for shear stress and strain. Modified Masing's rule and the experiment...
Condensation of steam on multiple horizontal tubes
Makas, Aytaç; Yamalı, Cemil; Department of Mechanical Engineering (2004)
The problem of condensation of steam on a vertical tier of horizontal tubes is investigated by both analytical and experimental methods in this study. A computer program is written to perform the analysis of laminar film condensation on the horizontal tubes. The program is capable to calculate condensate film thickness and velocity distribution, as well as the heat transfer coefficient within the condensate. An experimental setup was also manufactured to observe the condensation phenomenon. Effects of tube ...
Comparison of undrained shear strength by pressuremeter and other tests, and numerical assessment of the effect of finite probe length in pressuremeter tests
IŞIK, Nihat Sinan; ULUSAY, REŞAT; Doyuran, Vedat (2015-08-01)
There is a wide body of research reported in the literature which compare the undrained shear strength determined from various field and laboratory tests. The pressuremeter testing equipment and the related design techniques have been continuously refined. However, the undrained shear strength (S (u)) determined from the pressuremeter test (PMT) is generally higher than that obtained from other field or laboratory tests. In this study, numerical methods to consider the effects of length to diameter ratio (L...
Analytical modeling of fiber reinforced composite deep beams
Yağmur, Eren; Burak Bakır, Burcu; Department of Civil Engineering (2018)
Discrete fibers are often used as reinforcement to increase the tensile and shear strengths of concrete. For many years, the behavior of fiber reinforced composite members has been investigated both experimentally and analytically. The influence of fibers on the behavior of shear critical members is quite significant, therefore, it is inevitable to develop a method, which estimates the shear strength of fiber reinforced composite deep beams realistically. This is why one of the main objectives of this study...
Unified assessment of stress scaling factors for liquefaction engineering problems
Çetin, Kemal Önder (2014-01-01)
Most of the widely used seismic soil liquefaction triggering methods propose cyclic resistance ratio (CRR) values valid at a reference normal effective stress (σv,0) of one atmosphere, and a zero static shear stress (τst,0) state. Then a series of correction factors are applied to the CRR to account for the effects due to variations from the reference normal effective and static shear stresses (i.e., Kσ and Kα corrections). In the literature exists a number of stress correction factors used for seismic soil...
