ATSTRIP, specifically manufactured by A&T Engineering, is a Geosynthetic product specially designed for reinforcing backfill materials such as soil or fly ash in RS wall systems. Our innovative ATSTRIP incorporates tendons crafted from high tenacity polyester fibers, skillfully arranged into ten separate bundles and encased in a robust polyethylene sheath.
The high-performance polyester yarns within ATSTRIP are meticulously placed under tension, while the polyethylene sheath serves a dual purpose: safeguarding the polyester yarns and imparting the desired size and shape to the strips. This unique combination ensures optimal load-bearing capabilities and long-lasting durability.
ATSTRIP is available in a range of ultimate tensile strengths, offering versatility to suit various project requirements, with options spanning from 20KN to 100KN. Each strip boasts a width of 90mm, and we typically supply ATSTRIP in rolls measuring around 136 meters in length.
As an industry-leading product, ATSTRIP exemplifies our commitment to delivering superior Geosynthetic solutions. Its exceptional strength and reliable performance make it an ideal choice for reinforcing backfill materials in RS wall systems.
The primary function of reinforcement is to restrain
soil deformations. ATSTRIP improves the
mechanical properties of the soil through friction that occurred
between the soil and reinforcement surface. Reinforcing
elements where friction is important should
be aligned with the direction of soil reinforcement
relative movement. It also provide tensile resistance
to the soil.
The contribution of each transfer
mechanism for a particular reinforcement will
depend on the roughness of the surface, normal
effective stress, elongation, characteristics of the
reinforcement and the soil characteristics, including
grain size distribution, particle shape, density, water
content, cohesion and stiffness, it is also equally
important for better interaction between soil and
reinforcement.
Soil has an inherently low tensile strength but a high compressive strength. An objective of incorporating soil reinforcement is to absorb tensile loads or shear stresses within the structure. In absence of the reinforcement, structure may fail in shear or by excess of the deformation. This is illustrated by the simple model in Figure 2 & 3 which clearly shows the behaviour of a soil under unreinforced and reinforced condition.
A reinforced soil mass is somewhat analogous to reinforced concrete in that the mechanical properties of the mass are improved by reinforcement placed parallel to the principal strain direction to compensate for soil's lack of tensile resistance. The improved tensile properties are a result of the interaction between the reinforcement and the soil.
