Kazalo

From the geometric aesthetics of the 36.5-meter curve radius to the biomechanical protection of the 13mm composite structure, a true international standard athletic running track is the crystallization of mathematics, materials science and sports science.

IAAF's Standard Core Parameters

Basic geometric structure

Curve radius: 36.5 meters (accurate to ±0.01m), ensuring balanced centrifugal force for athletes, and speed loss in curves ≤3%;

Straight track length: 84.39 meters × 2 (straight section) + 115.61 meters × 2 (curved section), total length 400 meters ±0.04m;

Lane width: 1.22 meters ±0.01m, 8 tracks with a total width of 9.76 meters, and a 1.5-meter buffer zone is required on the outside of the 8th track.

Slope and drainage system

Transverse slope: 0.3%-1% (controlled by laser leveler) to prevent water accumulation;

Longitudinal slope: ≤0.1% (≤10cm per 100 meters drop) to avoid physical loss in the sprint section;

Drainage efficiency: drained within 30 minutes under heavy rain conditions (50mm/h), and the porosity of the permeable concrete layer is ≥25%.

Materials and Structure:

Layered Design (Total Thickness 13mm±1mm)

Elastic Layer: 9mm thick polyurethane + EPDM particle mixed layer, impact absorption rate 35%-50%;

Wear-resistant layer: 3mm self-grained surface layer, friction coefficient 0.7-0.8 (dry-wet state difference ≤0.05);

Anti-slip particles: particle size 0.5-2mm, density ≥5kg/㎡, resistant to 100,000 times of stepping on spikes without falling off.

Environmental protection indicators

Heavy metal content: soluble lead ≤10mg/kg (1/5 of China standard GB 36246-2018);

VOC release: ≤5g/L (72-hour environmental chamber method test);

Weather resistance: -40℃ to 70℃ cycle test for 1000 hours, tensile strength retention rate ≥90%.

Construction Accuracy

Line positioning

Use RTK satellite positioning system (accuracy ±2mm) to calibrate the center of the circle and the demarcation point of the straight and curved sections. The error of the circumference of 400 meters is ≤1cm. The arc length calculation formula of the curve is:

L=2π(r+0.3n)L = 2\pi (r + 0.3n)L=2π(r+0.3n)

(r=36.5m; n=lane number)

Večplastna konstrukcija

Bottom layer paving: polyurethane glue and black particles are mixed in a ratio of 1:5, the paver travel speed is ≤1m/min, and the thickness error is ±0.3mm;

Surface layer spraying: high-pressure airless sprayer (pressure ≥200bar) forms 0.5-1mm self-tightening texture, texture depth 0.3-0.8mm;

Marking process: hot-melt marking paint has weather resistance of level 5, and the line width error is ≤±1mm.

Drainage test

Simulate 50mm/h rainfall intensity, infrared thermal imager detects water accumulation points, and areas with unqualified slopes need to be milled and re-paved.

Acceptance criteria: hard-core testing with data

Physical performance

Flatness: 3m ruler full-field scanning, allowable error ≤3mm (qualified rate ≥90%);

Ball rebound rate: standard basketball rebounds 1.2-1.4m after falling 3m;

Anti-slip value: pendulum friction meter detection ≥47BPN.

Environmental protection acceptance

Sampling on site is sent to CMA laboratory to test 19 harmful substances (including polycyclic aromatic hydrocarbons and short-chain chlorinated paraffins);

TVOC≤0.08mg/m³ 7 days after completion (equivalent to indoor air quality standards).

Event-level certification

IAAF Class 1 certification: 12 dynamic performance tests must be passed (including energy return and vertical deformation);

China Athletics Association acceptance: submit full-process construction images and material traceability reports.

Multifunctional Expansion

Auxiliary training area: Long jump sand pit (≥9m×2.75m) and shot put throwing area (2.135m in diameter) can be integrated on the outside of the straight track;

Color zoning: Inorganic pigments are used to divide the training area (blue), competition area (red), and buffer area (green);

Intelligent upgrade: Strain sensors are implanted to monitor the changes in the elastic modulus of the runway in real time and warn of structural damage.

Pogosto zastavljena vprašanja

The IAAF recommends an optimal curve radius of 36.50 meters, and other common radii include 36 meters and 37.898 meters.

Each lane must be 1.22±0.01 meters wide, including the 5-centimeter lane line on the right.

It is mainly divided into breathable type (EPDM particles + polyurethane), mixed type (rubber particles + polyurethane), full plastic type (pure polyurethane) and prefabricated type (rolled material).

The horizontal slope is ≤1% (8‰ for curves and 5‰ for straights), the vertical slope is ≤1‰, and the slope of the high jump area must be ≤0.4%.

Including flatness (error of 3-meter ruler ≤3mm), thickness (≥13mm), impact absorption (35%-50%) and environmental protection (VOC≤5g/L).
