Test: Rigid Pavements-Components & Their Functions - Civil Engineering (CE) MCQ

The PQC denotes the pavement quality concrete which is used in rigid pavement.

 The base course may be required but in cement road it is not mandatory, it is better if it is provided.

 A cement slab is provided with both the longitudinal and transverse joints in both the direction as a slab is not laid at a stretch, it may be useful for identification.

The most commonly used test is plate bearing test which was developed by Westergard.

The greater compaction effort does not lead to any loss but if the compaction is less then there may be a failure.

The size of aggregate used in pavement GSB layer should be 0.075mm and have 5% fines.

The most commonly found failure in the GSB layer is pumping and blowing, these failure mainly take place due to the water.

The pavement thickness is constant and does not depend on granular sub base layer and if maintained properly it can increase the life span.

The most commonly used concrete for base is high quality concrete of lean concrete.

The spacing between construction joints in rigid pavement is formed for expansion and contraction of pavement which is 5.0 m.
