PQC Mix Design.

Our Services

Engineered for Strength, Durability, and Performance in Rigid Pavements

PQC Mix Design (Pavement Quality Concrete) is a highly specialized process for developing concrete specifically intended for rigid pavements, including highways, airport runways, taxiways, industrial floors, and container yards. Unlike general-purpose concrete, PQC is designed to meet unique flexural, durability, and workability demands associated with heavy traffic loads, abrasion, and climatic exposure. At Global Lab, our PQC mix designs comply with IRC:44-2017, IS 10262:2019, and IS 456:2000 standards, supported by NABL-accredited testing facilities. Each mix is scientifically proportioned to achieve the optimum balance between strength, density, and long-term serviceability — ensuring that your pavement performs reliably under the most demanding conditions.

Why PQCMatters.

To Achieve High Flexural Strength

Rigid pavements experience bending stresses from heavy, repetitive wheel loads. Unlike normal concrete, PQC is engineered for flexural (modulus of rupture) strength, typically ranging between 4.0–5.0 MPa, ensuring resistance to cracking and fatigue failure under traffic.

To Ensure Extreme Durability and Abrasion Resistance

PQC surfaces endure constant friction, weathering, and exposure to chemicals such as de-icing salts and oils. The mix is designed for low permeability, high abrasion resistance, and freeze–thaw stability, resulting in long-lasting pavement slabs with minimal maintenance requirements.

To Control Workability for Slip-Form Paving

PQC is placed using slip-form pavers or fixed-form paving machines, which require controlled, low-slump concrete. The mix must remain cohesive — not too dry or fluid — to ensure proper compaction, shape retention, and surface finish during machine placement.

To Minimize Shrinkage and Thermal Cracking

Drying shrinkage and thermal stresses can cause longitudinal or transverse cracks in pavements. A well-designed PQC mix includes optimized aggregate grading, low heat of hydration materials, and suitable admixtures to minimize shrinkage and maintain slab integrity across temperature variations.
