- 810 - SECTION 1019 -- SEALING COMPOUNDS
1019.01 Description
1.The sealing compounds covered are elastomeric single-component compounds.
1019.02 Material Characteristics
1.Type I (self-leveling) is a compound which has sufficient flow to give a smooth, level surface when applied in a horizontal joint at temperatures between 40°F and 122°F (4 C and 50 C).
2.Type II (non-sag) is a compound which allows application in vertical joints without sagging at temperatures between 40°F and 122°F (4 C and 50C).
3.The elastomeric single-component compound shall conform to the requirements of Federal Specific ation TT-S-230C "Sealing Compound, Elastomeric Type, Single Component".
4.Joint sealing material shall conform to the requirements in Table 1019.01, and documents shall be submitted that confirm the properties in Table 1019.01. Table 1019.01 Joint Sealing Compound Requirement As Supplied: Specific Gravity 1.010-1.515 ASTM D 792 Work Time, minutes 10 Tack-Free Time, at 77 F (25C), days 20-360 Cure Time, at 77 F (25C), days 14 Max.

(310 Max.) ASTM D 412 ASTM D 2240 ASTM D 2240 ASTM C 719 ASTM D 412
5.Sampling and testing of sealing compounds shall be in accordance with Federal Specification TT-S-230C for single-component sealing compounds.
1019.03 Procedures
1.Single-Component Sealing Compounds include polysulfides and polyurethanes.
2.The single-component sealing compounds (Type I or Type II) may also be used to seal joints in all types of structures where some movement is expected and where a tight seal against dust, dirt, wind, and water is required. Sealing Compounds 1019.04 - 811 - 1019.04 -- Acceptance Requirements
1.Sealing compounds on the Depar tment’s Approved Products List are acceptable.
2.Sealing compounds that are not on the Department’s Approved Products List may be accepted based on a manufacturer's certificate of compliance. - 812 - SECTION 1020 -- STEEL BARS FOR CONCRETE REINFORCEMENT
