SUBSURFACE DRAINAGE APPLICATION

Filtration that will allow long term passage of water into a subsurface drain system.
Woven Slit Films, (made with flat or tape character construction), are not allowed for this purpose.

  • c) These default filtration property values are based on the predominant particle sizes of in situ soil.  In addition to the default permittivity value, the engineer may require geotextile permeability and / or performance testing based on engineering design for drainage systems in problematic soil environments.
  • d) Site specific geotextile design should be performed especially if one or more of the following problematic soil environments are encountered:  unstable or highly erodible soils such as non-cohesive silts; gap graded soils; alternating sand/silt laminated soils; dispersive clays; and / or rock flour
  • e) For cohesive soils with a plasticity index greater than seven, geotextile maximum average roll value for apparent opening size is 0.30 mm.

SEPARATION APPLICATION

To prevent the mixing of subgrade soils & aggregate materials, when water seepage through the geotextile is not a critical function. Separation geotextiles are appropriate for unsaturated subgrade soils & for pavement structures meeting certain requirements set forth in AASHTO 8.3.2.

  Test Methods Units Requirements

a. Default Value. Permittivity of the geotextile should be greater than that of the soil. The engineer may also require the permeability of the geotextile to be greater than that of the soil.

DEGREE OF SURVIVABILITY

Required Degree of Survivability as a function of subgrade conditions, construction equipment and lift thickness (Class 1,2, and 3 properties are given in Table 1; Class 1 + properties are higher than Class 1, but not defined at this time) a

 

Low ground pressure equip.

< 25 kPa (3.6 psi)

Medium ground pressure equip. > 25 to < 50 kPa

(>3.6 to < 7.3 psi)

High ground pressure equip.

> 50 kPa (>7.3 psi)

Subgrade has been cleared of all obstacles except grass, weeds, leaves, and fine wood debris.  Surface is smooth and level so that any shallow depressions and humps do not exceed 450 mm (18 in.) in depth or height.  All larger depressions are filled.  Alternatively, a smooth working table may be placed. Low (Class 3) High (Class 1) High (Class 1)
Subgrade has been cleared of obstacles larger than small to moderate-sized tree limbs and rocks.  Tree trunks and stumps should be removed or covered with a partial working table.  Depressions and humps should not exceed 450 mm (18in) in depth or height. Larger depressions should be filled. Moderate (Class 2) High (Class 1) Very High (Class 1+)
Minimal site preparation is required.  Trees may be felled, delimbed, and left in place.  Stumps should be cut to project not more than +150mm (+ 6 in) above subgrade.  Geotextile may be draped directly over the tree trunks, stumps, large depressions and humps, holes, stream channels, and large boulders.  Items should be removed only if placing the geotextile and cover material over them will distort the finished road surface. High (Class 1) Very high (Class 1+) Not Recommended
  • a) Recommendations are for 150 to 300 mm (6 to 12 in) initial lift thickness.  For other initial lift thicknesses:
    • 1) 300 to 450 mm (12 to 18in) reduce survivability requirement one level
    • 2) 450 to 600 mm (18 to 24 in) reduce survivability requirement two levels
    • 3) lt;600 mm (24 in) reduce survivability requirement three levels
  • For special construction techniques such as pre-rutting, increase the geotextile survivability requirement one level.  Placement of excessive initial cover material thickness may cause bearing failure of the soft subgrade.

STABILIZATION APPLICATION

To provide both separation & filtration in areas of wet, saturated conditions.  In some installations, reinforcement is also provided.  This product is typically used where a high groundwater table is present & or areas that are prolonged to periods of wet weather.  In the application of embankment reinforcements where stress conditions may cause subgrade foundations or stability failure, THIS IS NOT APPROPRIATE TO USE.
