PAVEMENT QUALITY CONCRETE


Pavement Quality Concrete (PQC) is cement concrete made with large size aggregates in accordance with IRC specifications and laid over a dry lean concrete sub-base. This construction is used specifically for highway concrete pavements and for airport runway pavements as it can take heavy loads.

Pavement quality concrete is different from normal conventional concrete by using 32 mm size aggregate and very less slump of 15-25 mm. This type of concrete requires little more cement content as compared to that of normal concrete (min. 360 Kg/Cum) and is mostly designed for M40 grade of concrete. It is suitable for heavy traffic volume and mostly for construction of National Highway. Slump Requirement for PQC is very small around 15-25mm when laying with Automatic pavers. Polythene sheet is provided between PQC & DLC.

We are offering FC-ESTEEMA PQC (PCE Based admixture ) and FC-SNPLAST PQC (SNF Based admixture) as a best solution of Pavement Quality Concrete (PQC).
