• Tread surface: 82 mm

Deformability and elasticity

Lying measurement

The deformability is measured in new condition and following permanent tread load using ball penetration tests with a calotte (r = 120 mm) and
a penetration force of 2,000 N (corresponding to approx. 200 kg).

Walking measurement

The deformability is determined in new condition and after the continuous tread load with a cow’s foot modeled steel base and a penetration force of 2,000 N (approx. 200 kg). Where: the “artificial cow’s foot” in its dimensions is the one used in the con­tinuous tread load.

Permanent tread load

The measurement of the continuous tread load is carried out with 250,000 alternating loads at 5,000 N (corresponds to approx. 500 kg) on a test bench with a round steel foot.

The steel foot is adapted to the natural conditions as an “artificial cow foot”. The foot has a diameter of 105 mm and therefore a contact area of 75 cm²; the carrying edge of the hoof is simulated by a 5 mm wide ring on the periphery of the sole that projects 1 mm above the rest of the surface.

Permanent tread load

After the continuous tread load on a test stand with 250,000 alternating loads at 5,000 N there was observed no noticeable wear and no damage on the surface of the mat.

No lasting deformation was observed.

Deformability and elasticity

Lying measurement

In the ball penetration tests in new condition with a calotte (r = 120 mm), penetration depth was 6.2 mm. The resulting calculated bearing pressure of 42.8 N/cm² indicates a load on the carpal joints when lying down and getting up. Elasticity was measured following a permanent tread load exerted by a steel foot (contact area: 75 cm²) with 250,000 alternating loads at 5,000 N.

Following the endurance test, the penetration depth of the calotte decreased from 6.2 mm to 6.0 mm. The bearing pressure increased from 42.8 N/cm² to 44.2 N/cm² (see Fig. 3a).

This means that deformability and elasticity slightly decrease.

Walking measurement

In the impression tests with an artificial cow foot  was the depth of penetration of the walkway surface in new condition 5.6 mm. The calculated bearing pressure is 26.67 N/cm². The elasticity was measured after the permanent load tread by a steel base (contact area 75 cm²) with 250,000 alternating loads measured at 5,000 N.

The depth of penetration decreased after the endurance test of 5.6 mm to 5.3 mm. This means, that deformability and elasticity of the walkway covering decrease (see Fig. 3b).
