Beijing Daxing International Airport

Runway & apron crack control with Ecocrete™ PP Mesh Fiber

Challenges & Solution

Early-Age Cracking, Heavy Loads, Freeze–Thaw — Solved

Plastic shrinkage & temperature gradients: PP mesh fiber distributes throughout the matrix to relieve stress at crack tips and limit crack formation.

Heavy aircraft & braking zones: Added toughness and impact resistance help pavements tolerate dynamic loads and reduce raveling.

Freeze–thaw & de-icing exposure: Non-corrosive, chemically resistant polypropylene fibers support long-term durability without rust risk.

Placement efficiency: Fibers are easy to dose and mix; compatible with slip-form paving and pump placement when dispersion steps are followed.

Project teams reported cleaner saw-cut joints and reduced unplanned repairs at touchdown and braking areas. Fiber-reinforced concrete helps keep critical pavements in service longer and lowers lifecycle costs.

Durable Concrete, Cleaner Operations

Project teams reported tighter crack widths, cleaner saw-cut joints, and robust slab edges in high-stress zones (touchdown and braking areas). The fiber approach supports lifecycle cost savings by reducing unplanned repairs and keeping critical pavement in service longer.

Project Overview

Safer, Longer-Lasting Pavements for a Mega-Hub

Beijing Daxing International Airport handles extremely high traffic and heavy wheel loads. To help control early-age shrinkage cracking and improve durability under repeated takeoffs, landings, and FOD-sweeping cycles, the concrete pavement mix incorporated Ecocrete™ PP Mesh Fiber. The 3D fiber network helps bridge micro-cracks, enhances impact and abrasion resistance, and supports long-term service life for runways, taxiways, and aprons.

Application: runway slabs, taxiways, apron stands
Fiber type: Ecocrete™ PP Mesh Fiber (typical lengths 12–19 mm)
Typical dosage: 1.0–2.0 kg/m³ (adjust per mix design and climate)
Benefits: crack control, improved toughness, better edge durability, reduced spalling risk
