Dajulong Homogeneous Through-colour Flooring Empowers Terminal T2 of Chengdu Shuangliu International Airport to Build a New Benchmark for High-resilience Transportation Hubs
Project Background
As a major aviation hub in western China, Chengdu Shuangliu International Airport’s Terminal T2 handles a daily passenger flow of over 120,000. The high-frequency passage of baggage carts and trolleys places extreme demands on flooring materials. Plagued by issues such as joint cracking and high maintenance costs, the original stone flooring launched a renovation and upgrading project in 2023. Dajulong Homogeneous Through-colour Flooring won the bid with its core advantages of high wear resistance, zero maintenance, and full-lifecycle environmental friendliness. It fully covers core areas including check-in zones, security screening corridors, and baggage claim halls, reshaping the resilience of the airport’s flooring system.
Challenges & Selection Requirements
Superior Mechanical Load Capacity
The flooring must withstand 3,000 daily rollings by baggage carts (with an axle load ≥ 800kg), achieve an impact resistance of ＞50MPa, and completely avoid cracking and deformation.
Fire Safety
It must strictly meet the Class B1 flame retardant standard specified in GB 8624 for aviation hubs, producing no dripping, low smoke, and no toxicity when exposed to open flames.
24/7 Cleanliness
With an antibacterial rate of ＞99.9%, the flooring should resist penetration by stains such as aviation fuel and coffee, and support daily deep cleaning by floor scrubbers.
Rapid Construction
Construction in the terminal must be carried out in phases, with a single-area operation window ≤ 6 hours. Materials need to be pre-cut for immediate laying and use.
Dajulong Homogeneous Through-colour Flooring Solutions
Tailored to the extreme working conditions of the terminal, Dajulong’s technical team designed a structure-reinforced + function-modularized solution:
Material Innovation: 6mm-thick Dajulong Homogeneous Through-colour Flooring was adopted. Its full-body homogeneous structure ensures the pattern remains clear even after wear. The dense UV-coated surface layer achieves a wear resistance of over 25,000 cycles (per EN 660 standard), delivering a service life three times longer than traditional PVC flooring.
Function Integration:
Check-in Islands: Dajulong Homogeneous Through-colour Flooring embedded with conductive copper foil layers maintains a stable electrostatic dissipation value of 10^6–10^9Ω, ensuring zero interference with the precision instruments of baggage scales.
Security Screening Zones: Customized X-ray radiation-resistant Dajulong Homogeneous Through-colour Flooring, with a lead equivalent of 0.25mmPb, builds an invisible protective barrier for staff.
Baggage Carousel Zones: Dajulong Homogeneous Through-colour Flooring with a diamond embossed surface achieves an R11 slip resistance rating under wet conditions. Combined with an oil-resistant formula, it reduces oil stain residue by 80%.
Intelligent Paving: Based on BIM modeling, over 5,000 special-shaped panels were prefabricated. Using antistatic adhesive and pulse hot air welding, the team completed an intensive 2,000㎡ paving in just 8 hours, with joint strength reaching 18N/mm² (per EN 1399 standard).
Implementation Highlights
Dynamic Load Verification: Simulated tests involving 200,000 rollings by baggage carts showed that the surface indentation of Dajulong Homogeneous Through-colour Flooring was only 0.03mm, far below the stringent aviation flooring standard of ≤ 0.5mm.
Green Closed Loop: 100% of the old flooring was recycled and repurposed. The newly installed Dajulong Homogeneous Through-colour Flooring obtained the LEED V4.1 Environmental Product Declaration (EPD) certification, reducing the full-lifecycle carbon footprint by 62%.
Operation & Maintenance Outcomes
Economic Benefits: Compared with the original stone flooring, Dajulong Homogeneous Through-colour Flooring reduced annual maintenance costs by 73%, and shortened the fault response time from 48 hours to 2 hours.
Safety Improvement: After renovation, the safety accident rate related to the terminal flooring dropped by 91%. In 2024, the airport was awarded the IATA (International Air Transport Association) "Best Airport Ground Safety Award in the Asia-Pacific Region".
Experience Optimization: Passenger surveys showed that 82% of respondents were satisfied with the flooring’s slip resistance and noise reduction performance. Notably, complaints about slips caused by wet shoes on rainy and snowy days dropped to zero.
Industry Paradigm Value
The Chengdu Shuangliu Airport project stands as a model application of Dajulong Homogeneous Through-colour Flooring in ultra-high-frequency transportation scenarios, verifying its reliability under the extreme passenger flow of 2,000 people per square meter per day. The case was included in the Innovative Materials Chapter of the China Airport Construction White Paper and promoted the China Civil Airports Association to issue the Technical Specification for Resilient Flooring in Terminals (No. CAPSE-MT-2024), with multiple parameters of Dajulong Homogeneous Through-colour Flooring designated as industry benchmarks.
