This study examines the changes in friction and texture following the application of shotblasting to an asphalt pavement. The primary aim is to assess both the immediate impact and the lasting effects of the treatment. To achieve this, a road segment featuring an asphalt surface in optimal condition was selected. The segment was then divided into two sections: one treated with shotblasting, and the other serving as a control section with no modifications. Friction and texture measurements were taken at various time points after construction in both sections, providing data to quantify the impact and duration of the shotblasting treatment. In terms of friction, the longevity of the shotblasting appears to be 1.2 years, and for texture, the longevity was closer to 3 years. However, surface texture components were affected by a deicing operation conducted 1 year after shotblasting, which may have influenced, especially in terms of friction, the observed trend in the second and third year. The results of this study will inform the use of shotblasting as a surface treatment to improve skid resistance.
