Measurement of tyre/pavement interface stresses under moving wheel loads

摘要: In order to design more economical pavements, it is necessary use the most accurate input parameters possible. Tyre/pavement interface stresses are one of important inputs in any pavement system and therefore requires appropriate definition. This paper describes a prototype Vehicle–Road Surface Pressure Transducer Array (VRSPTA) developed for measurement tyre/pavement moving wheel load. It illustrates that caused by can be adequately measured vertical, transverse longitudinal directions. As this was an experimental which contains some inaccuracies, certain improvements current suggested.
