This research aimed to provide guidance to contractors seeking to increase the macrotexture and microtexture of an asphalt pavement as well as to provide a systematic approach to decision-makers regarding retexturing methods. In the first stage of the research, waterblasting, grooving, skidabrading and slurry seal techniques were evaluated using the Choosing by Advantage method. After this evaluation, it was concluded that waterblasting and skidabrading offer the best value for money. In the second stage, waterblasting and skidabrading were applied to two 300-meter sections of asphalt pavement. Measurements were made of the macrotexture and microtexture before and after the treatments by varying the speed and pressure. The results revealed that while the skidabrading treatment satisfactorily met the macrotexture and microtexture requirements of RAP 314, the waterblasting method did not. Finally, in the third stage, Kruskal-Wallis, ANOVA and Spearman's correlation statistical tests were used to explore the relationships between the variables. This analysis showed that there is a moderate negative correlation between speed and macrotexture but not between speed and microtexture. On the other hand, with waterblasting, a moderate positive correlation was observed between pressure and microtexture while no correlation was found between pressure and macrotexture.
