DESCRIPTION
Mechanical interlock creates a flexurally stiff platform which distributes load evenly, reduces rutting and minimises differential settlement. Interlock between the grid and a well-graded aggregate prevents lateral movement of particles at the base fo the fill layer. This in turn prevents upward movement of subgrade fines by pumping.
Amerasia Geogrid
Distribute applied loads over a greater area reducing vertical pressure on the subgrade. This allows for a longer design life compared with a similar unreinforced section. If designing for a specific lifetime, this allows for significant reductions in base course thickness.
Material Savings
Amerasia geogrids allow up to a 30% reduction of base course material thickness in flexible pavement systems. Soils are an essential material in all types of construction and must be treated as an engineered material. Project engineers are often forced to develop solutions and give proper attention to soils when problematic subgrade conditions are encountered. However, soils should also receive full attention when they are used as fill material in applications like paved and unpaved roads (base reinforcement) and construction over weak soils (soft soil stabilization). The proper engineering evaluation should occur not only when utilizing an expensive, high quality granular fil with a carefully controlled gradation, moisture content and great structural characteristics, but also when utilizing a readily available poor quality borrow of fine-grained clay. For a project to be success, soils require the full attention of project engineers.
