In this study, the effect of the quasi-rate of loading in the crushing of tough black sand will be studied experimentally. The Black tuff sand was obtained from the Al-Hala area (Al Tafila) in southern Jordan. Sand chemical composition is composed mainly of SiO2 with a considerable amount of Fe2O3, Al2O3, and CaO oxides. The experimental works will...

Rutting is one of the most important distresses in asphalt concrete pavements. It is typically caused by consolidation or lateral movement of the materials (reorientation of aggregate particles) due to traffic loading in a hot climate. The ability to predict rutting depth in asphalt concrete pavements is an important aspect of pavement design. In t...

Sand is one of the most abundant, naturally occurring materials in many parts of the world, which is used in local rural areas in infrastructure projects such as in the construction of low volume paved and unpaved road layers due to their availability at low cost and scarcity of other suitable construction materials. Several geotechnical solutions...

A relationship to predict the load-displacement curve for axially loaded piles in sandy soil is presented by using the tri-linear softening model to describe the shaft load-displacement relationships, as well as a bi-linear model is adopted to characterize the unit end resistance-displacement reaction in the region of the pile's tip soil. Subsequen...

Recently, using rocks, especially limestone, in the facades of buildings has become pervasive due to its characteristics such as hardness, insulation, and aesthetic view. Meanwhile, interest in building insulation materials has been increased to prevent indoor humidity of building walls and provide thermal comfort with less energy usage. As a resul...

This study aims to investigate the variation of P-wave velocity as a function of water saturation. In addition, by using a regression analysis, a predictability of saturated P-wave velocity from dry P-wave velocity and rock's hardness has been examined. In order to perform this study, one hundred cylindrical rock core samples, fifty samples each ob...

A new approach for estimating friction capacity of open-ended piles driven into sand is presented in this work. The approach is based on the hypothesis that the unit shaft friction profile along a closed-ended pile can be extrapolated to get the unit shaft friction profile along a similar open-ended pile by multiplying the former profile by the app...

The main objective of this study was to evaluate the use of glass fibers and cement as stabilizing agents for highly expansive soil. Fibers with two aspect ratios (12 and 30 mm in length) were added as percentages of the soil’s dry weight (0.5%, 0.75%, 1%, and 1.5%), the cement was added in two percentages by dry weight soil (2% and 6%). Sixteen gr...

In this study, the effect of the quasi rate of loading in the crushing of black tough sand will be studied experimentally. The experimental works will be conducted at different normal stresses, different relative densities, and different rates of loading using the direct shear tests. All test specimens were prepared with uniformly graded sand, pass...

The influence of pozzolanic materials on calcium-based soil stabilization technique has recently attracted researchers’ attention as such materials may catalyze the occurrence of pozzolanic reactions due to their high SiO2 and AL2O3 content. In this study, the effect of adding natural zeolite, which is a common pozzolanic material, on soil stabiliz...

This study offers an alternative analytical solution, for one and two-dimensional consolidation problem, for functionally-homogenous isotropic clay layer. The fundamental analytical solution presented in this study is derived based on the Laplace transform which eliminates the time-dependent and Heaviside's inversion theorem to extract the inverse....

Methane and carbon dioxide are of major concern as greenhouse gases; the landfills have the problem of controlling these gases. Al Akaider in Jordan is the second biggest landfill suffers controlling gases as it lacks a cover design system. In this work, the main goal is to investigate the appropriateness of amended expansive clayey soil in Irbid a...

Observations derived from updated field test databases indicate that total axial pile capacity of driven piles in sand continues to increase with time long after complete dissipation of excess pore pressure generated by pile driving. The increase in pile capacity with time is attributed to time-dependent increase in shaft capacity which is termed i...
