to produce crushed concrete from concrete airfield pavements

May 15, 2020 Pavement Quality Concrete (PQC) is a 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.
