REINFORCEMENT 90/90 KN/m

For the railways' and roads' lower pavement where exceptional resistance to penetration (CBR test) is needed, due to the high traffic density as well as high pressure per cm2.


DATA REQUIRED IN ACCORDANCE WITH INTERNAL RULES OF CEN/CENELEC EU STANDARDS

  • Tensile strenght MD/CMD
  • Elongation
  • Resistance to static breakdown (CBR-test)
  • Hole size
  • Waterpermeability
  • Durability

ADVANTAGES OF GEOCOMPOSITE
  • Good mechanical features which provides efficient separation
  • Excellent filtering properties
  • Exceptional resistance to damage
  • Increases the stability of soil
  • Easy handling and instalation
  • Environmentally neutral
GEOCOMPOSITE APPLICATION:
Geocomposite Martin M-A-T sandwich 600 PP reinforced with infinitive fiber (integfrated into PP filter with staple fiber) has direct implementation on the muddy soil, and on the soil which has high moisture concentration. It also reduces the usage of filling material up to 30%.
 WARNING at installing GEOCOMPOSITE:
  • Rolls (tapes) must not be longer than 50 yards in setting
  • Implemented geocomposite must not have wrinkles during installaion
  • Overlapp must be min 30 cm
  • On geocomposite joints must be riveted with noncorrosive nails ( 1 n/m) or by sewing of compounds
  • Resistance in alcaline environment

*Possible changes if there is need for higher elongation.

**Filter part of geocomposite could be changed in the case of stronger water flow.
