This study aims to optimize the bonding performance between wearing course and used pavement or underlying layer further improve service quality durability of open-graded friction with small particle size aggregate (ultrathin OGFC). The ultrathin OGFC including waterborne epoxy resin emulsified asphalt (WEA) concrete 9.5 mm nominal maximum gradation was optimized. construction timing mixture de...

We use confocal microscopy to explore shear melting of colloidal glasses, which occurs at strains of approximately 0.08, coinciding with a strongly non-Gaussian step size distribution. For larger strains, the particle mean square displacement increases linearly with strain and the step size distribution becomes Gaussian. The effective diffusion coefficient varies approximately linearly with she...

A linear stability analysis of rotating Boussinesq flows including shear, μ-gradients and radiation losses leads to modification of the classical Ledoux criterion for convective equilibrium. The role of shear in spreading the radial extent of the convective layers is briefly investigated, and we found that some effects may be expected in the latest nuclear evolutionary stages of massive stars, ...

We present here a microscopic study of the effect of shear on a dense purely repulsive colloidal suspension. We use multispeckle diffusing wave spectroscopy to monitor the transient motions of colloidal particles after being submitted to an oscillatory strain. This technique proves efficient to record the time evolution of the distribution of relaxation times. After a high oscillatory shear, we...

Shear connectors are used in steel beam-concrete slabs of composite frame and bridge structures to transfer shear force according to design loads. The existing Y-type perfobond rib shear connectors are designed for girder slabs of composite bridges. Therefore, the rib and transverse rebars of the conventional Y-type perfobond rib shear connectors are extremely large for the composite frames of ...

The shear strength of a 4-ply unidirectional composite laminate consisting of carbon fibers (T650-35) and a polyimide matrix (HFPE-II-52) was measured over a temperature range of 25 to 315C. The tests were performed using a Iosipescu test sample, modified to provide a more uniform shear stress distribution across the gauge section and loaded with an Arcan type test fixture. The test specimen de...

In the literature ample attention is given to the assumptions on which the interpretation of shear-test results from a Jenike shear tester are based. Very little is said, however, about the influence on the test data of the construction of the apparatus itself. In the work described here, the authors have investigated the influence of the loading mechanism on the results. The original Jenike-ty...
