1061.01 Description. The waterproofing membrane system materials shall
consist of a penetrating primer, coal tar pitch emulsion, fiber glass, slurry seal top coat, and a sand asphalt seal protection layer.
1061.02 Penetrating Primer. The primer shall be a highly penetrating solution
that is compatible with the coal tar pitch emulsion and suitable for use on portland cement concrete surfaces. Asphaltic primers will not be permitted.
1061.03 Coal Tar Pitch Emulsion. The coal tar pitch emulsion shall be
compounded of heavy closed ring hydrocarbons dispersed in water by means of a combination of irreversible colloidal clays.
a.Sampling and Testing. Prior to approval and use of the material for coal tar pitch emulsion and penetrating primer, the Contractor shall submit a certification by the manufacturer of each material, stating that it meets these requirements. This shall not constitute a waiver on the part of the Department of any requirements with respect to samples and samplings, and the right is retained to perform any or all of the tests specified.
b.Ingredient Materials. The coal tar pitch used in production of this material shall have a specific gravity at 77 °F (25 °C) of 1.20 to 1.27. By continuous hot extraction with benzol, after digesting in toluol, the insolubles ordinarily described as free carbon shall not be less than 12 percent. A cylinder of the pitch 1/2 in. (13 mm) in diameter and 6 in. (150 mm) long, which has been immersed in melting ice for at least 30 minutes, shall withstand being bent double without developing cracks at the point of greatest deflection; a duplicate cylinder, which has been immersed in melting ice for at least an hour, shall withstand twisting for two complete turns of 360 degrees each Waterproofing Membrane System Art. 1061.03 without showing cracks or fractures. The pitch shall not be fluxed back with light oils, solvents, or any other adulterants before or during the emulsification process. Since these characteristics are not subject to test after emulsification, they are to be certified by the manufacturer. The emulsion shall contain no sulphite pitches, asphalt, bentonite, coal dust, soluble soaps, or sulphonic acid and shall have sufficient thixotropic property so that at temperatures of 70 °F (21 °C) it may be temporarily reduced with agitation, to applied liquidity without addition of adulterants, to provide easy workability with brush or squeegee, and then reset in place.
c.Properties.
1.Specific Gravity. A sample of the emulsion shall show a specific gravity at 77 °F (25 °C) of between 1.22 and 1.29.

3.Nonvolatile Matter. A sample of the emulsion when treated in an oven according to ASTM D 2939, shall show a minimum nonvolatile matter of 52 percent. This residue, when heated from room temperature to 518 °F (270 °C) in an oven within 30 minutes time, shall show a loss of not more than ten percent by weight (mass).
4.Ash Content. A sample of the residue from the determination of nonvolatile matter according to ASTM D 2939 shall show an ash content of 30 percent to 40 percent.
5.Resistance to Freezing. * A sample of the emulsion fortified with antifreeze shall be tested according to ASTM D 244. After exposure to a temperature of 0 °F (–18 °C) shall return to a homogeneous consistency with stirring. *NOTE: The emulsion shall be fortified with antifreeze where climatic conditions surrounding the material in transit or storage are such to make resistance to freezing necessary.
6.Consistency. The emulsion when spread to a thin film with a spatula on a sheet of standard 18 lb (8.16 kg) paper shall flow with a uniformly smooth nongranular consistency, free from coarse particles which are either apparent or which cause film voids as the material is drawn out to a smear.
7.Flammability. The material shall be nonflammable when exposed to flame.
8.Drying Time. A test panel prepared according to ASTM D 2939, and exposed at a temperature of 77 °F (25 °C) and 50 percent relative humidity in activated air, shall set for touch within three hours and set within four hours. Art. 1061.03 Waterproofing Membrane System
d.Cured Film Performance.
1.Resistance to Motor Oil, Gasoline, and Distilled Water. A 2 coat film of the emulsion with a minimum cured thickness of 1/16 in. (1.5 mm) shall be prepared on a 6 x 6 in. (150 x 150 mm) tile according to the Methods of Testing Films Deposited from Bituminous Emulsions, ASTM D 466. The cured film shall be tested according to ASTM D 466, using the above specified test liquids, except the test period shall be 48 hours.
