The durability of pavement layer desponds on the type of mineral aggregate. In 1999, while rebuilding road infrastructure in Kielce (Poland), a SMA wearing coarse layer with hydrated lime was placed on the town’s main streets. SMA mixture contained 63% of quartzite aggregate. The hydrated lime was dosed into the SMA mixture to replace 30% of the filler mass. The pavement surface condition after 12 years life was very good. The hydrated lime additive was found to have a positive effect on water resistance of SMA pavement.
