Standard Specification for
Adhesive Lubricant for Installation of Preformed
Elastomeric Bridge Compression Seals in Concrete
Structures1

This standard is issued under the fixed designation D 4070; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This specification covers an adhesive lubricant for
facilitating the insertion and positioning of preformed elastomeric bridge compression seals in either concrete or steel-faced
joints, and which bonds the seal to the joint faces to waterproof
the joint.

2. Referenced Documents

2.1 ASTM Standards:
D 1084 Test Methods for Viscosity of Adhesives2

3. General Requirements

3.1 The adhesive lubricant shall be a one-component,
moisture-curing, polyurethane compound extended with aromatic hydrocarbon solvent. The compound shall provide adequate lubrication for insertion of the seal into the joint and, in
the actual field application, shall bond the seal to the joint face
throughout repeated cycles of expansion and contraction,
effectively sealing the joint against infiltration of moisture.

4. Physical Requirements

4.1 The material shall conform to the physical properties
described in Table 1.

5. Sampling

5.1 Samples of the adhesive lubricant shall be 1 L (1 qt)
consisting of a composite taken from three or more separate
containers chosen at random from the same batch. A batch or
lot shall be considered as all finished material that was
manufactured simultaneously or continuously as a unit prior to
packaging. Each of the containers sampled shall be resealed
and marked for identification.

5.2 Samples shall be taken at the point of manufacture or
warehouse prior to delivery, or at the point of delivery from
each lot.
