Biaxial geogrid: definition, application, and benefits of using biaxial geogrids A biaxial geogrid is a geosynthetic material designed with soil reinforcement in two orthogonal directions: longitudinal and transverse. This has a high tensile strength in both axes, and its versatility is therefore suitable for many applications in civil engineering. Such geogrids are manufactured using materials… Continue reading Biaxial geogrid

What is backfill material? Every aspect of civil engineering plays a vital role in creating a durable and long-lasting structure. One crucial material is backfill. Although this material seems to be an underdog, it plays a significant role in filling the gaps in the foundation. Before we delve into the depths of backfill material, let’s understand… Continue reading Backfill material

What are Atterberg’s limits? Constructing a structure requires several green flags before building the foundation. One of the most important checks is soil testing, which determines the soil’s behaviour. There are several methods of soil testing, but the Atterberg’s limit test is considered the most reliable. It is the foundation level of soil testing. It determines… Continue reading Atterberg limits

What is asphalt? Asphalt is a composite material obtained by the result of commixing mineral aggregates and the distillation by-product known as bitumen, which is obtained from petroleum. A long-lasting cost-effective product used mainly in road construction and rehabilitation, asphalt’s smooth elastic flexible features make it an indispensable raw material in the infrastructure industry. Its… Continue reading Asphalt roads

Asphalt reinforcement: definition, use, and type Asphalt reinforcement is the process of reinforcing the layers of asphalt pavements to improve the service life of the road. Asphalt can be defined as the mixture of a petroleum biproduct with aggregate such as sand, gravel and a binder such as bitumen. It’s the final surface which is applied to… Continue reading Asphalt reinforcement

How are they built and what are their benefits? Asphalt pavement is a composite material made of stones and sand mixed with asphalt. Asphalt is a dense, viscous, dark liquid derived from petroleum. The substance is sometimes called bitumen, a name that emphasizes its adhesive nature and its resistance to damage from water and oil.… Continue reading Asphalt pavement

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. It has big holes or openings that strengthen the layers… 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 angle of repose is the angle at which the material stops sliding and begins to rest in a state of equilibrium. The slope that sand takes naturally when poured on a flat surface is the angle of repose.… Continue reading Angle of repose
