Pavement quality concrete for roads, taxiways and heavy-duty hardstands.
Flexural-strength-designed concrete for rigid pavements — city roads, industrial estates, port yards and highway corridors.
Inside Alpha PQC
Alpha PQC is pavement quality concrete — a low-slump, high-flexural-strength mix designed for rigid pavements that carry wheel loads directly rather than transferring them through a structural frame. The governing property is flexural strength (modulus of rupture), tested on 150×150×700 mm beams, not compressive cube strength alone.
Mix design follows IRC:44 with a target 28-day flexural strength of 4.5 N/mm² for highway and heavy industrial work, and characteristic compressive strength typically in the M30-M45 range. Aggregate gradation, cement content and water-cement ratio are set for low workability, high abrasion resistance and low drying shrinkage.
Supply is sequenced to the paving method. Slipform and fixed-form paving needs consistent low slump load after load, delivered at a rate that keeps the paving train moving without cold joints. Dispatch is planned around paving output in m³ per hour, not per truck.
Built for rigid pavements
Target 4.5 N/mm² modulus of rupture at 28 days per IRC:44, verified on beam specimens alongside routine cube testing.
Hard, well-graded crushed aggregate and low W/C ratio for surfaces under repeated heavy-axle loading.
Loads sequenced to the paver's output so the train never starves and no cold joints form mid-panel.
Slump held tight load to load — slipform paving fails on variation, not on average.
Gradation and cement content optimised for low drying shrinkage, reducing mid-panel cracking between joints.
Detailing guidance for contraction, expansion and construction joints, dowel bars and tie bars per IRC:15.
Built for these projects
NH and SH rigid pavement stretches, service roads, toll plaza aprons.
Container yards, warehouse aprons, truck parking, weighbridge platforms.
IT campus internal roads, township roads, industrial estate carriageways.
Bus depots, logistics parks, loading docks, aircraft-adjacent hardstands.
