Road tests

summer

The main tasks during road tests is to assess the impact of tires on driving safety, driver comfort during driving and operating parameters of vehicles.

For this purpose the road division of the Tire Testing Center uses modern technical equipment, the latest testing methods, as well as a test field located in the Yaroslavl region near the village of Tunoshna.

Types of test and test sites:

Summer cycle

Winter cycle

1. Determination of adhesion properties. Braking

To determine the adhesion properties while braking on wet and dry surfaces, a special area if the test field with heavy-duty asphalt concrete pavement equipped with wateringing system. When conducting this test, measurements of the braking distance of a vehicle in the prescribed speed range are made.

Section length – 100 m
Width – 8 m

2. Determination of adhesion properties. Acceleration

To determine the adhesion properties while acceleration a direct long section is used allowing a vehicle to reach speed of 100–120 km / h. An estimated figure of the test is acceleration time in the prescribed speed range.

Section length – 500 m
Width – 6 m

3. Assessment of stability and controllability

This assessment is carried out during testing on changing lanes, where the behavior of the tires is checked during rapid changes of direction. Test results generated from the speed measurements and the freeform driver’s comments. The section is located in the centre of the test field, thus providing the necessary security when running controlability tests.

Acceleration line length – 500 m
Section length – 150 m
Width – 20 m

4. Summer tests for compliance with UNECE Regulation № 117

4.1. Determination of the coefficient of friction on wet surfaces.

Tests are conducted on a platform with a certified pavement equipped watering system.

Section length – 100 m
Width – 8 m

4.2. Tests to measure the sound level of the tire rolling.

For testing, a special section is used in accordance with the technical requirements of the regulations for test field and certified under TUV for Europe.

Section length – 20 m
Width – 20 m

All of the above tests are performed with precision equipment operating on the basis of GPS and GLONASS satellite systems, as well as acoustic system of high sensitivity.

Equipment is registered with the State Register of Measurement Devices of the Russian Federation is certified accordingly. Testing procedure. Issuance of a certification testing protocol. Obtaining the approval of tires type with a certificate of conformity.
