Jointed Plain Concrete Pavement

Concrete Pavement

Concrete pavement is a rigid pavement structure, which distributes heavy axle loads over a large area by beam action. This means concrete pavements are less sensitive to the sub-grade support and do not require the thick road base/ sub-base layers like asphalt concrete pavements.

Method

Jointed Plain Concrete Pavement (JPCP)

JPCP contains enough joints to control within the location of all the expected natural cracks. All necessary cracking occurs at joints and not elsewhere in the slabs. JPCP does not contain any steel reinforcement. However, it requires load transfer devices (e.g. dowel bars) at transverse joints and deformed steel bars (e.g. tilebars) at longitudinal joints. The spacing between transverse joints is typically between 5m (16.4ft.) and 6.3m (20.7ft.) for slabs of 200-300mm (8-12in.) in thickness.

Benefits:

  • Well-graded coarse and fine aggregates.
  • Mixture is fluid and flows easily.
  • Durable.
  • Requires less maintenance.
  • Low life-cycle cost.
  • Maximum usage of local materials.
  • Reduces carbon footprint during the construction process.
  • Effective at handling oil and grease.
