Abstract:

Skid resistance is an important aspect of pavement preservation that enables road authorities to be proactive in efficient and effective pavement management. At present, multiple treatments are applied worldwide as part of preventive maintenance programs in order to restore and combat deficient skid resistance on asphalt pavement surfaces. Amongst these treatments, shotblasting has been introduced as an effective technique for the restoration of skid resistance. Its main characteristics include its simple structure, convenient operation, high working efficiency and it is environmentally friendly, in that it is a dust free process that recycles all materials used and generated by the process. The present study aims to evaluate the long term performance of shotblasting as a pavement preservation technique. Friction and macrotexture data were collected periodically after the application of the shotblasting in multiple site sections along a motorway under investigation. The collected data were comparatively analyzed with respect to the time after the application of the shotblasting treatment, while taking into consideration the effect of the seasonal variations on skid resistance levels. The analysis results demonstrated that the overall “good effect” of shotblasting has duration. However, the crucial issue surrounding the effect of seasonal variations on skid resistance is not resolved by implementing the shotblasting technique and this is a matter of major concern. More findings and details are included in the paper.
