    Abstract: This paper aims to analyze slope stability based on the numerical simulation using Plaxis software. The mechanical parameters of soil layers constituting the slope are evaluated from laboratory results and numerical simulations of in-situ pressuremeter tests. The study of the slope consists to determine the failure surface and the corresponding saf... Show More

    Abstract: Pre-compression by preloading is used to accelerate the consolidation settlement of a site ahead of construction so that post-construction settlement would be minimal. The principal aim of the technique is to remove the primary consolidation settlement anticipated under the proposed load with or without partial compensation for secondary compressio... Show More

    Abstract: Paving materials characterization in terms of resilient modulus (MR) has become crucial for pavement design and analysis. In fact, it is extremely difficult to measure MR in laboratory as well as in field. The main objective of this study is to achieve a basis for the performance based design specifications of flexible pavements in Egypt. Thus, a m... Show More

    Abstract: Infiltration rate in soil is a measure at which the soil is able to absorb rainfall. It replenishes the soil moisture deficiency and the excess moves downward by the force of gravity called deep seepage or percolation and builds up the groundwater table. The study was conducted in three large Upazilas under Rajshahi district from 2002 to 2013 to es... Show More

    Abstract: Self- Compacting concrete (SCC) is a special type of concrete that is able to flow and compact under its own weight and can occupy all the spaces in the form without any vibration effect, and at the same time cohesive enough to be handled without bleeding or segregation. The required compaction properties are achieved by adding super-plasticizers a... Show More

    Abstract: In the present study elastic buckling of steel columns with three different cross sections, i.e. square, rectangle and circle cross sections, and two different boundary conditions, i.e. fixed-free(F-F) and pinned-pinned (P-P) boundary conditions, under axial compression has been investigated. At first, the basic equations of the problem have been g... Show More
