FRICTION


TRI staff are well versed in design issues and assist our customers in developing and performing responsive performance testing programs. TRI laboratories perform a variety of performance testing services to support design verification and confirmation of material performance properties. This testing includes:

TRI performs Interface Friction/Direct Shear testing to investigate slope stability.
geosynthetic-geosynthetic interfaces
soil-geosynthetic interfaces
internal GCL shear and GCL interfaces
large-scale soil shear strength
long-term creep at the interface
constant load or constant strain testing
