Pervious Sheeting
AASHTO M 182.
2.4.7.3
Liquid Membrane-Forming Compound
ASTM C 309, white-pigmented, Type 2, Class B.
2.4.8
Liquid Chemical Sealer-Hardener Compound
Compound shall be magnesium fluosilicate which when mixed with water seals
and hardens the surface of the concrete. Do not use on exterior slabs
exposed to freezing conditions. Compound shall not reduce the adhesion of
resilient flooring, tile, paint, roofing, waterproofing, or other material
applied to concrete.
2.4.9

(subparagraphs 5.1 to 5.4). Material shall be 13 mm (1/2 inch) 1/2 inch
thick[, unless otherwise indicated].
2.4.10
Joint Sealants
2.4.10.1
Horizontal Surfaces, 3 Percent Slope, Maximum
**************************************************************************
NOTE: For horizontal surfaces subject to jet fuel,
specify FS SS-S-1614.
**************************************************************************
ASTM D 1190 or ASTM C 920, Type M, Class 25, Use T.
ASTM D 1854 for
surfaces subjected to jet fuel.
2.4.10.2
Vertical Surfaces Greater Than 3 Percent Slope
**************************************************************************
NOTE: Specify ASTM C 920 for vertical surfaces
greater than 3 percent slope and not subject to jet
fuel, gasoline, fuel oil, etc. For vertical
surfaces greater than 3 percent slope and subject to
jet fuel, specify FS SS-S-200, no sag.
**************************************************************************
ASTM C 920, Type M, Grade NS, Class 25, Use T.
[FS SS-S-1614] [FS SS-S-200,
no sag].
2.4.11
Epoxy Bonding Compound
ASTM C 881. Provide Type I for bonding hardened concrete to hardened
concrete; Type II for bonding freshly mixed concrete to hardened concrete;
and Type III as a binder in epoxy mortar or concrete, or for use in bonding
