The design of Municipal Solid Waste (MSW) landfills requires the selection of representative MSW material properties. The profession’s understanding of the mechanical response of MSW has evolved significantly in recent years, but many aspects of the response of MSW remain uncertain. A research project involving five organizations was conducted to systematically evaluate the factors that affect ...

The lunar soil is an ideal building material for future base construction. In order to improve the strength of soil, basalt with similar composition was used simulate due lack real and simulated reinforced sodium silicate. study direct shear mechanical properties by silicate solidification, a series tests SEM microstructure were carried out, stress-displacement whole process curve obtained. Inf...

this research study employed a mixed-methods approach to investigate the test takers’ perceptions and anx- iety in relation to an english language proficiency test called community english program (cep). this study also evaluated the direct and semi-direct modes for speaking module of this test. to this end, 300 eng- lish as foreign language (efl) students were recruited in the study as test ta...

Introduction State and local transportation agencies frequently use opengraded aggregates for wall, roadway, and bridge construction. The primary advantages of using this type of material in wall and abutment applications are ease of constructability, lighter in-place density than well-graded materials, very low fine content, free-draining characteristics, and simpler quality assurance testing,...

Recent experimental observations of intersonic shear rupture events that occur in a variety of material systems have rekindled interest in the intersonic failure phenomenon. Since the early 1990s, engineers and scientists working in all length scales, from the atomistic, the structural, all the way up to the scale of the earth’s deformation processes, have undertaken joint e€orts to study this ...
