A The term “modified” in the table relates to the specimen preparation. The use of the joint seal as the specimen source requires that more plies than specified in either of the modified test procedures be used. Such specimen modification shall be agreed upon between the purchaser and the supplier prior to testing. The hardness test shall be made with the durometer in a durometer stand as recommended in Test Methods D2240.

B Sample prepared in accordance with Method A of Test Method D518.

C Cracking, splitting or sticking of a specimen during a recovery test shall mean that the specimen has failed the test.

D The reference section and subsections are those of specification D 3542 – 08 Preformed Polychloroprene Elastomeric Joint Seals for Bridges.

E Speed of testing shall be 0.5 ± 0.05 in. (13 ± 1.3 mm), minimum at room temperature of 73°F ± 4°F (23 ± 2.2°C). The sheets of sandpaper are not used.

SECTION VI – Installation Blockout Tolerances Guide: For parallelism, use 1/8” allowable up to 2-1/2” joint sealants and 1/4” for 2-1/2” and larger seals.

In determining joint width tolerance, if the joint is 1/2” wider at one point then the expected maximum opening is an additional 1/2”. If that calculation is found to be out of the specified movement range of the compression seal, you will need to recut the joint and go with a larger seal.

Install Delastic® Preformed Compression Seals into joints that are sound (no loose substrate), clean (no dirt, rust, scale, slurry or other debris), dry and free from other contaminants.

Delastic® Preformed Compression Seals shall be installed utilizing DSB 1520 Lubricant Adhesive. DSB 1520 is a single component, moisture curing polyurethane in a solution of aromatic hydrocarbon solvents and used as an adhesive lubricant and bonding agent for neoprene compression seals.

DSB 1520 Lubricant Adhesive exceeds the requirements of ASTMD-4070, Standard Specification for Adhesive Lubricant for Installation of Preformed Elastomeric Bridge Compression Seals in Concrete Structures. The Contractor shall furnish a manufacturer’s certification that Lubricant Adhesive complies with the requirements of ASTM D-4070.

DSB 1520 Lubricant Adhesive should be applied liberally to the preformed compression seal or to the expansion joint walls prior to inserting the seal into the joint. The seal must be inserted into the joint immediately following the application of the DSB 1520 Lubricant Adhesive.

Do not allow DSB 1520 lubricant adhesive to freeze.

Optimal working temperature is 70F. Do not apply when ambient temperatures are below 40F.

Opened containers of DSB 1520 Lubricant Adhesive must be used the same day opened. Unused material cannot be saved even if the container is tightly resealed as the product is moisture reactive and will gel when exposed to

Specification instructions. Note: Seals should not be stretched to facilitate installation. Stretching the seal will diminish the performance of the seal.

Every effort should be made to supply and install preformed compression seals in continuous lengths. Contact manufacturer for procedures should splices be unavoidable.

Cleanup: Excess DSB 1520 Lubricant Adhesive and Tools and equipment used in the application of Lubricant Adhesive should be cleaned with toluene, xylene or a blend of the two. Clean hands with soap and water.

Contact manufacturer for upturn and/or downturn installation procedures. Refer to manufacturer datasheets and MSDS sheets available at www.dsbrown.com for additional product and safety information.

SECTION VII – Packaging and Shipment Preformed compression seals are packaged in continuous joint lengths in cardboard boxes or on wooden reels as the project requires.

DSB-1520 is packaged in 1 gallon pails.

Shipment is typically palletized.

SECTION VIII – Measurement and Payment Preformed compression seals shall be measured as the distance along the center line of the joint and paid for at the contract unit price per linear foot.

Payment will be made under:

PAY ITEM PAY UNIT

Preformed Compression Seal Lineal Foot

Payment will be full compensation for all work necessary to complete the items includes furnishing and installing the preformed compression seal.
