Experimental Investigation on Rheological Properties of Recycled Asphalt Pavement Mastics

Applied Rheology, 2015
Studies have shown that rheology of asphalt mastic plays an important role in pavement performance, specifically for the case of recycled asphalt pavement (RAP) mastics which contains mostly aged binder.

Methods and Points of Attention for the Direct Tension Test on Rock

Journal of MMIJ, 2016
Compared to uniaxial or triaxial compression tests on rocks, direct tension tests on rocks are not common in practice. As is well known, the reasons are because underground rock masses are usually under compressive stress state and/or because the direct ...

Dynamic rock tensile strengths of Laurentian granite: Experimental observation and micromechanical model

Journal of Rock Mechanics and Geotechnical Engineering, 2017
Tensile strength is an important material property for rocks. In applications where rocks are subjected to dynamic loads, the dynamic tensile strength is the controlling parameter.

Analysis of concrete fracture in “direct” tension

International Journal of Solids and Structures, 1989
Abstract The direct tension test on concrete specimens is analysed using finite elements. The analysis shows that the behaviour after peak load is strongly non-homogeneous and involves asymmetric crack propagation. These observations, which are supported by experimental evidence, have consequences for deriving “stress-strain” relations from direct ...

Tensile Behavior of Green Concrete Made of Fine/Coarse Recycled Glass and Recycled Concrete Aggregates

Buildings
The study conducted axial tensile strength tests on concrete samples that replaced conventional aggregates with recycled aggregates. In Series I, using FNG instead of FNA resulted in a reduction in compressive strength by 12.8–49.8% and tensile strength ...

Study on the mechanical traits, failure mechanisms, energy responses, and influencing factors of columnar jointed basalts under direct and indirect tensile conditions

Frontiers in Earth Science
In this study, by merging mesoscopic damage mechanics, the probabilistic strength principle, and continuum mechanics, the visuals of columnar jointed basalts (CJBs) featuring various joint arrangement patterns are converted into inhomogeneous numerical ...

Three-dimensional microscopic model reconstruction of basalt and numerical direct tension tests

工程科学学报, 2019
The presence of discontinuities and randomly distributed pores in basalt specimens greatly affects their engineering properties, such as the failure mechanism and strength. Therefore, investigating the mechanical and fracture behaviors of basalt affected
