A laboratory compaction approach to characterize asphalt pavement surface friction performance
The main objective of the current study is to investigate whether surfaces produced by a standardized roller compaction method, using several compaction modes, could be used to simulate the frictional properties of the as-constructed pavement surfaces of a new, full-scale hot mix asphalt (HMA) road test section. Laboratory and field friction measurements were compared. The frictional characteristics of asphalt mixtures with different aggregate sizes, mix gradations and binder contents were investigated. Results indicated that the laboratory roller compaction method closely simulates, from a frictional point of view, the field construction processes. Thus, this methodology may be integrated into the existing mix design practices to assess asphalt mix frictional characteristics and to optimize the mix design accounting for both structural and functional requirements.
