VTI has carried out acceptance testing of companies that would like to do road surface monitoring in Finland. This has been done on commission of the Finnish Road Administration. This kind of acceptance testing has been done in Sweden by VTI in cooperation with the Swedish Road Administration several times (four times). With the experience of the tests in Sweden a test method adjusted for the Finnish needs have been composed. The purpose of the method is to accept or reject the participating companies for doing either object or network measurements or both. This is done by checking the validity and repeatability for the object part and the reproducibility for the network part. The tests for the object part involve measurements at test sections including measuring with reference methods as well as repeated measurements on a route. For the reproducibility test, done at the network measuring acceptance, runs with different combinations of vehicles and drivers/operators are carried out. The tests give answers to questions like: - The technical skill to measure according to the procurement specifications. - The ability and type of organisation to take care of and process data under given circumstances like this test. - The ability to deliver data of right quality in time. To be accepted as a contractor of network level measurements the company also has to be accepted for object measurements.
