Rolling Resistance : Measurement Methods for Studies of Road Surface Effects

• This report is intended to provide basic knowledge about measurement methods which relate to the road surface influence on rolling resistance, as well as to provide some information about equipment that are useful for collecting rolling resistance data. The methods used were literature studies, compiling experience from recent research projects (not yet reported), using other Deliverables in MIRIAM SP 1 and, above all; a rather extensive field experiment within MIRIAM called the round robin test.The work in MIRIAM is the first time one has looked at rolling resistance measurement methods applicable to road surface effects systematically, and evaluated various measurement equipment, both in some detail and from an overall point of view.As an overall conclusion it may be stated that rolling resistance measurement methods are still in their infancy. This applies to testing of tyres, where the many standards produced so far totally miss that the rolling resistance is a tyre/road interaction and therefore have serious drawbacks. This also applies to testing road surfaces where the tyre/road interaction has indeed been a major concern from the beginning, but where field testing appears to be extremely difficult.Whereas Phase One provided fair possibilities to study rolling resistance of car tyres, there was very little possibility to study measurements with heavy vehicles and their tyres. As the latter are the sources for a major part of the transportation fuel consumption and air pollution (perhaps up to half of it), this means that Phase One of MIRIAM SP1 had resources to address only a limited part of the measurement problem.This report includes comprehensive lists of research needs, both in general and within the next Phase of MIRIAM.Phase One of MIRIAM gave the partners a lot more knowledge about rolling resistance measurements, which will be most useful in further work. The work and its result have created a good platform from which further steps can be taken in Phase Two of MIRIAM. This report should provide major progress towards the goal of producing a useful measurement method and standard.
