TRACKS

Testing and Certification

Track Surface Testing Services

The pavement surfaces at test tracks, proving grounds, and motorsports facilities are a valuable and important asset. Ensuring success on a fixed budget leaves no room for error—the project must be done right the first time.

We provide a wide range of track surface test services. We’re also ISO/IEC 17025:2017 accredited for ISO 10844 and UNECE R117 conformity measurements, further demonstrating our technical competence and adherence to international quality standards for mechanical testing.

Measurement and Certification

We provide acceptance testing of new test tracks and periodic checking of existing tracks at intervals required by the relevant standards. We provide accredited conformity testing to the current ISO 10844:2021 standard and prior ISO 10844:2014, ISO 10844:2011, and ISO 10844:1994 versions of the standard. We also provide accredited test services for certifying Wet Traction Lanes and Wet Braking Lanes in accordance with UN ECE Regulation 117 (UNECE R117).

For surface texture

Many surfaces require surface texture measurements including those certified to ISO 10844 and UN ECE R117. Our most frequently used surface profiler called RoboTex adheres to Class DE of ISO 13473-3, characterization of pavement texture by use of surface profiles. RoboTex is a laser-based texture profiling device that scans along the entire length of the track. We provide specialized measurements of microtexture using a high resolution laser-based system. And finally, accredited texture measurements using “sand patch” in accordance with ISO 10844:1994 Appendix A, EN 13036-1, and ASTM E965.

For irregularities, profile, IRI, and megatexture

Most tracks including automotive test tracks and motorsports tracks should be smooth! Our testing services and ISO/IEC 17025:2017 includes accreditation for testing evenness. We provide straightedge testing in accordance with EN 13036-7. We also used both inclinometer and laser-based profilers according to ASTM E950, EN 13036-5. These results can be used for calculating International Roughness Index (IRI) or also megatexture according to ISO 13473-5 and EN 13036-6.

For Sound Absorption

ISO 10844 testing requires an impedance tube device meeting ISO 13472-2, measurement of sound absorption properties of road surfaces in situ. We use a two-microphone method for acoustical absorption. The measurement is conducted in-situ, without the need for extracting core samples and the associated patching repairs.

Consultation and Engineering

We provide consultation and engineering services for the design and construction of tracks of all types including ISO 10844 tracks and wet braking lanes according to UNECE Reg 117. Simply following road construction specifications and methods will not produce a track that meets the demanding requirements of automotive and motorsports standards. Successful construction tracks requires expertise in pavements and specifications that span surface texture, smoothness, and various automotive responses including grip and acoustics. Our pavement and acoustics experts can help you design, plan, and verify the end result meets the necessary requirements.

ISO 10844:2011 exterior noise test track standard

As the ECE and other regulations worldwide continue to evolve, the ISO 10844:2011 exterior noise test track standard will be an important component of vehicle and tire noise testing in the coming years. Tracks that had previously complied with the 1994 version of the standard are not necessarily conforming to the new standard, which has led to many owners to seek out resurfacing projects.

ISO 10844: 2014 vs. 2011

ISO 10844 was last republished in 2014. This comparison by Douglas Moore shows the changes in the 2014 version compared to the 2011 version.
