Surface Treatment Macrotexture and Bicycle Ride Quality

This report summarizes the results of measurements of macrotexture on a set of Caltrans and local government pavement surface treatments, and the results of bicycle vibration measurements and a survey of bicycle ride quality on most of those sections. The work was performed to address concerns regarding ride quality after a modified-binder seal coat (chip seal) was applied. Macrotexture was measured in terms of mean profile depth (MPD). Statistical correlations between macrotexture, roughness (in terms of International Roughness Index [IRI]), bicycle vibration, and bicycle ride quality are presented. Conclusions are presented regarding the MPD values measured on various road sections and on three MPD measurement methods that were used. Findings are presented regarding the MPD values from other types of treatments. Results are also presented regarding the effects of trafficking on MPD values. Correlations between bicycle vibration and MPD are shown, and between MPD, IRI, bicycle vibration, and bicyclists’ perception of ride quality and pavement acceptability for use by bicycles. Recommendations are made regarding a range of MPD values that might be used to select chip seal specifications based on “acceptability” where bicycle ride quality is an issue, selection of remedial treatments, naming conventions for chip seals, and the use of additional rolling to reduce the texture of chip seals.
