Topic 4 Construction of Rigid Pavement

What is rigid pavement?

• constructed from reinforced concrete slabs

• constructed from cement concrete

• constructed from aggregates

A is refer to

• Tranverse joint

• Expansion joint

• Construction joint

• Longitudinal joint

B is refer to

• Transverse joint

• Expansion joint

• Construction joint

• Longitudinal joint

What is the function of rigid pavement?

• To act as binder materials to the soil

• To provide level, comfortable and safe surface.

• To act as water proof layer to stop infiltration of surface water.

• To provide a convex surface and drainage

This layer provides characteristics such as friction, smoothness, noise control and drainage.

• Surface course

• Binder course

• wearing course

• base course

The base course generally consists of aggregate or _______aggregate or soil and lean concrete

It functions primarily as structural support. This refer to :

• Surface course

• base course

• sub-base

• sub-grade

The materials used for rigid pavement:

• Concrete

• joints

• reinforcement

• tarmac

________ are discontinuities in the pavement slab that are necessary to allow for expansion, contraction, and warping

This diagram is refer to:

• Jointed Reinforced Concrete Pavement (JRCP)

• Jointed Plain Concrete Pavement (JPCP)/ Mass Concrete

• Continuously Reinforced Concrete Pavement (CRCP)

• Prestressed Concrete (PSCP)
