Abstract

In statistics, the evaluation of measurement uncertainty is used as the technical carrier for the quality evaluation of measurement results of automatic testing equipment. In this paper, the uncertainty of the measurement results of the automatic testing system of Twin-wheel side force coefficient, which is an important testing equipment for pavement lateral force coefficient, is evaluated according to the testing methods specified in the Chinese transportation industry standards. The sources of uncertainty are analyzed, and the calculation steps of uncertainty combination are simplified. The purpose of this paper is to solve the scientific problems such as insufficient basic data and heavy calculation encountered by engineering inspectors in the evaluation of uncertainty, and to provide support for the evaluation of road traffic engineering inspection quality.
