What is aperture stability modulus? The Aperture Stability Modulus (ASM) is also called In-plane torsional rigidity. It can be defined as a critical parameter that evaluates the effectiveness of geogrids. These are usually made of polymer materials such as polyester, polyethene, polyvinyl alcohol, or polypropylene. They have large openings or apertures that reinforce soil and… Continue reading Aperture stability modulus
What is the aperture size of geosynthetic materials? Geosynthetic materials have an important coefficient to perform the function of geotechnical project applications, such as reinforcement of the soil, filtration, and drainage. The value of this parameter can be measured depending on the specific type and application; it reflects the size or spacing of reinforcement elements… Continue reading Aperture size
Definition, factors affecting it, and its importance in geotechnical studies What is the angle of repose? The maximum angle of repose is defined as that angle at which a pile of granular material may heap without collapsing. In other words, this represents the angle between the plane which is horizontal and the surface of the… Continue reading Angle of repose
What is the definition of allowable axle load? The civil engineering industry is dynamic and vast. Each factor plays an important role. Every aspect is crucial, from understanding soil behaviour to constructing a structure. On-time transportation of construction materials is essential for a smooth construction process. However, efficient transportation requires good transport infrastructure, which includes… Continue reading Allowable axle load
What are aggregates? Aggregates are granular materials such as sand, gravel, crushed stone, crushed hydraulic cement concrete, or air-cooled iron blast-furnace slag, used with hydraulic cement to produce either concrete or mortar. They are divided into two groups by size, as coarse aggregate (material retained on the 4.75-mm (No. 4) sieve), and fine aggregate (material… Continue reading Aggregates
Access roads What are access roads? Access roads play a critical role in transportation and infrastructure development. They serve specific functions, providing connectivity to areas like construction sites, forests, state institutions, and sources of raw materials. Despite their simplicity compared to regular roads, access roads offer numerous benefits, especially in specialized operations like timber harvesting… Continue reading Access roads
