Neighborhoods: anti-seepage composite geotextile testing need to follow which test specifications, and routine testing items.

Answer:

There is a special GB ah GBT-1998 I was the production of geotechnical materials
(G / sq.m), film thickness (mm), mass per unit area deviation (%), breaking strength (KN / m), the product quality (GB / T-1998) (KN), the equivalent pore diameter O55 (mm), the vertical permeability coefficient (cm / s), the hydrostatic pressure (Mpa), the tearing strength (KN), the CBR breaking strength (KN) The And the front two said the basic almost, but hope that a detailed description can make you more clearly point.
