Recently published Standards for Geocells by the ASTM, [32] ISO [30] and other countries (e.g., the Netherlands), [33] is the natural outcome of recent developments in the field of cellular confinement systems: new polymeric materials for geocells, extensive published research, accepted performance-based testing methods and an expanding ...
Neoloy Geocells may be considered a sustainable road construction method. [26] By improving the structural properties of low strength materials, Neoloy Geocells can replace quarry aggregate with marginal, lower strength materials, such as locally-available sand; recycled and reclaimed construction materials (RAP and recycled concrete). Not only ...
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
