Expansion Joint Board

Product Details:

We are leading Mastic Pad Manufactures, DEESA Jolly Bitulex Softboard is processed from cane fiber, mastic pad raw material tested and proven to provide the best resilience.We provide high quality mastic pad which is best in industry. Impregnated with Bitumen in various percentages, it is a perfect base material for expansion joint fillers. The board’s compression and recovery characteristics confirm to the U.K., U.S.A. and Indian Standards much above the required averages.

Jolly Board Expansion Joint Filler:

Jolly Board Expansion Joint Filler is manufactured from water-resistant, bitumen impregnated, cane fiber. It is available in a wide range of sizes, both as boards & strips in thicknesses of 10 MM, 12 MM, 18 MM, 19 MM, 25 MM.

 

Jolly Expansion Joint Filler displays excellent resistance to compression, with outstanding recovery characteristics. The fillers are environment-friendly as opposed to the environment destroying thermocole/plastic expansion joint filler.

Mastic Pad Applications:

Mastic Pads External wall cladding: Filling structural expansion & structural separation joints in the block & insitu concrete construction. Mastic Pads Traffic surfaces: Filling expansion joints in motorways, roads, runways, pedestrian areas, bridges, curbs etc. Internal surfaces Filling expansion joints across concrete floors, including screed floors with underfloor heating. Roofs & floor finish Ideal for filling expansion joints in concrete floors. Building superstructures Filling expansion joints in basements, retaining walls, site slabs, subways & other water excluding structures. Reinforced concrete structures Expansion joint fillers in piers and lateral supports like abutments. Expansion strips Against existing or between adjacent constructions and insets in concrete paving like drains, manholes, etc. Industrial Flooring

Internal finishes Various other flat works and concrete floors according to the state of the art and local regulations.

Physical Properties:

Jolly Bitulex Expansion Joint Fillers conform to the following required standards

ASTM -D. 1751-83/D.545 – 84 Testing

`concrete paving and structural construction’

`pre-formed expansion Joint Fillers for concrete’

Department of Transport – London 1986: `specification to highway works, part 3, clause 1015′ B.S. 1142 for Standard Specifications for Expansion Joint Fillers.

IS 1838(Part-I) 1983 Standard Test of Expansion Joint Fillers.

Strong points and performance characteristics: Compression to 50% thickness in the initial state:- Recovery is 80/84% Weathering and compression to 50% thickness: – Recovery is 70/76%. Jolly Bitulex returns to more than 70% of its original thickness after three applications of pressure sufficient to reduce its thickness by 50%. Extrusion: No effect (0.75 mm) Unaffected by temperature changes Low moisture absorption due to bitumen impregnation. Standard Bitumen content 10-20-35%. Other possibilities upon request.

Product Details:

Strip Seal Expansion Joint: is a mechanical device adapted for sealing an elongated gap formed between two adjacent road slab sections by providing a continuous support for vehicles crossing the gap while allowing the desired temperature responsive movement of the road slab sections. A single elastomeric neoprene rubber strip is secured to the adjacent roads sections on either side of the gap through heavy duty edge beams under a specially designed profile.

Strip Seal Expansion Joint system consists of an elastomeric gland mechanically locked between two steel edge members providing a superior watertight sealing system. The rugged design of the Strip Seal Expansion Joint can easily accommodate the high loads of vehicular traffic while effectively sealing expansion joints in bridges and structures with movements up to range up to 80 mm (+/- 40 mm).

Strip Seal Expansion Joints can be manufactured to accommodate a variety of field configurations along with multidirectional movements.

These Expansion Joints has been engineered so that the neoprene seal can be inserted either prior to or after the securing of the steel shapes to the superstructure. Machined Steel shapes maximize seal insatiability and minimize manufacturing tolerance associated with overall Steel shape manufacture.

Functions of Strip Seal Elastomeric Joint:- •

Permits the expansion/contraction of the span to which it is fixed without causing any distress or vibration to the    structure
• They cause no inconvenience or hazard to the road user and offer good riding comfort
• Should be capable of withstanding the traffic loads including dynamic effects
• Surface exposed to traffic should be skid free and resistant to polishing
• Ensure accessibility for inspections and easy maintenance with all parts vulnerable to wear being easily    replaceable
