The PQC denotes
The PQC denotes the pavement quality concrete which is used in rigid pavement.
The layer not required in cement road is
The base course may be required but in cement road it is not mandatory, it is better if it is provided.
The cement slab is provided with
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 soil sub grade design is done by
The most commonly used test is plate bearing test which was developed by Westergard.
Failure in rigid pavement occurs due to
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 particles preferred in GSB layer of pavement is
The size of aggregate used in pavement GSB layer should be 0.075mm and have 5% fines.
The failure in GSB layer of rigid pavement is
The most commonly found failure in the GSB layer is pumping and blowing, these failure mainly take place due to the water.
The drainage layer of pavement can
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 base course uses
The most commonly used concrete for base is high quality concrete of lean concrete.
The spacing between construction joints in rigid pavement is
The spacing between construction joints in rigid pavement is formed for expansion and contraction of pavement which is 5.0 m.
