High Skid-Resistant Pavements: The Effect of Gritting Parameters
https://orcid.org/http://orcid.org/0000-0002-9328-4756
Turkey’s Highway Technical Specification (HTS) necessitates gritting of pavement surface courses for the regions where the high-polishing resistant aggregate (PSV ≥ 50) is lacking or hard to reach. The gritting is defined as the spreading of 1–3 mm magmatic origin aggregates with the rate of 1.5–2 kg/m2 to the pavement surface after the roller’s first pass. This study investigates the effect of gritting construction parameters (aggregate type, size, amount, and time of spreading) on pavement surface texture and skid resistance by monitoring the performance of nine test sections over more than three years under real traffic and environmental conditions. Considering the field observations, reduction in skid resistance with respect to traffic, in terms of equivalent standard axle load, is modeled for all test sections, and their service life is calculated. The results show that test sections gritted with the slag-origin aggregates perform better and yield nearly twice the service life of the one specified in the HTS. Accordingly, using slags in pavement gritting would provide safer and more sustainable highways.
