Meeting the ChallengeBuilding highway and airport runways to last is a challenging engineering assignment. Espe-cially when the pavement must withstand heavy traffic, weather extremes, debilitating fuels and de-icing chemicals. This requires reliable products with a proven track record.

Delastic® Preformed Pavement Seals have been specified and installed on highways and airport runways since 1960. Through time, they have proven to be durable and cost-effective.

Delastic® Preformed Pavement seals effectively protect concrete pavement in highways, airport aprons and airport runways by keeping moisture, debris and incompressible material out of the joint opening.

Delastic® Preformed Compression Seals

Delastic® Preformed Pavement Seals are the primary sealing system for concrete pavement slabs in high-ways, airport aprons and runways. Delastic® Preformed Pavement Seals offer these advantages:• Dramatic reduction in concrete joint

spalling• Extended performance life

(15-20 years)• Resistance to jet fuel, de-icing

fluids and other chemicals

• Installation not weather sensitive• Speed of installation • Product cleanliness• No sandblasting required• Ease of inspection• Delastic® Preformed Pavement

Seals meet or exceed ASTM D 2628, FAA P604, AASHTO M-220, USACE 02762, USACE 32-13-73 and CRD-C 548 Standard Specifications

Delastic® Preformed Pavement Seals for concrete pavement have one main purpose: to prevent water and debris from entering the joint. If that happens, the pavement can crack, chip, buckle and prematurely deteriorate.Delastic® Preformed Pavement Seals are also known as compression joint seals. They are installed in a compressed state and remain in contact with the joint walls while allowing the concrete pavement to expand and con-tract during temperature changes. Delastic® Preformed Pavement Seals are extruded from compounds of polychloropene (neoprene) which meet or ex-ceed current ASTM standard specifications.There are other joint seal products available, but each has its disadvantages. Silicone sealants must be installed under very clean and dry conditions to perform properly. This cleanliness requirement is often difficult to achieve in a construction environment. Hot pour asphalt systems do not age well and require the pavement joints to be resealed often, significantly increasing the overall cost.

Delastic® Preformed Pavement Seals meet ASTM standard specifications. They are also recognized by the FHWA, U.S. Army Corps of Engineers, the U.S. Air Force, the FAA, consulting engineers and other agen-cies as an effective, long-lasting concrete pavement joint seal solution.

Delastic® Preformed Pavement Seals have been successfully used on high per-formance concrete pavements through-out the U.S. Many of these installations have protected pavements located in ex-treme hot and cold climates in excess of 20 years.

Delastic® Preformed Pavement Seal Properties

A The term “modified” in the table relates to the specimen preparation. The use of joint seal as the specimen source requires that more plies than specified in either of the modified test pro-cedures be used. Such specimen modification shall be agreed upon by the purchaser and seller prior to testing. The hardness test shall be made with the durometer in a durometer stand as rec-ommended in Method D 2240.

B Test in accordance with Procedure A of D 518.

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

D The reference sections are those of this speci-fication.

Delastall® Kompressor for seals from 7/16 to 1-5/8 inches

Trough & Tapper™ for seals from 1-1/4 to 4 inches nominal width

PushPro® for seals from 9/16 to 1-1/4 inches

Delastic® Preformed Pavement Seal InstallationIn all instances, the joint walls must be reasonably clean and free of spalls with a properly designed width. To facilitate seal installation, D.S. Brown offers its Delastall™ Kompressor, PumpPro™, PushPro™ and Trough & Tapper™ installation tools for rental or purchase. Pump-Pro™ pumps DSB 1516 lubricant adhesive onto the joint walls prior to insertion of the preformed pavement seal using the PushPro™.

Lubricants DSB 1516 and DSB 1520 lubricant adhesives are used during installation to lubricate the seal when it is inserted in the joint opening. The minimum installation temperature on job sites should be 40°F (4°C) to ensure proper performance of the lubricant adhesive.

Material SpecificationsFor Delastic® Preformed Pavement Seals, ASTM standard specification D 2628 applies. DSB 1516 lubricant adhesive meets ASTM D 2835 requirements while DSB 1520 lubricant adhesive meets ASTM D 4070.
