Expansion Joint Filler Board Road construction

About Expansion Joint Filler Board Road construction

In road construction, an Expansion Joint Filler Board is a compressible, non-extruding material used to fill gaps between concrete slabs to accommodate expansion and contraction due to temperature changes, traffic load, or shrinkage.

Heres a practical overview for your use:

What is an Expansion Joint Filler Board?

Its a preformed board placed in expansion joints of rigid pavements, runways, bridges, or concrete roads, to:

• Absorb expansion during heat

• Prevent cracking or blowouts

• Maintain joint integrity

Common Specifications

Types of Filler Boards

1. Bitumen Impregnated Fiber Board (BIFB)

   • Traditional, economical, semi-rigid

   • Moisture and chemical resistant

2. Cross-linked Polyethylene (XLPE) / EVA Foam

   • Lightweight, flexible, and rot-proof

   • Excellent rebound

3. Resin or Rubber-Based Boards

   • High-end, durable, heavy-duty applications

Installation Tips

1. Cut to required width and insert into joint gap before concreting.

2. Ensure full depth and vertical alignment.

3. Leave top 510mm recess for joint sealant (like polysulfide or bitumen).

4. Secure board to prevent movement during pour.

Benefits

• Withstands compressive stress from concrete expansion

• Ensures clean joint edges

• Prevents water ingress

• Easy to install and cut

• Complies with IRC and MoRTH standards (India) or ASTM D1751 (USA)
