Abstract
The main purpose of this research is studying stripping of asphalt mixtures. Key factors were
the aggregate properties and the suitable methods to control and assess the stripping distress in
laboratory conditions. Our case study was the "Zanjan-Qazvin" freeway in which this distress
is manifested extensively. The aggregates for the tests were selected from the sections in
which stripping were more serius. stripping was found to be caused by excess values of
siliceous minerals. This resul were obtained using XRF & XRD analyses. Primary estimation
of stripping was determined using boiling test over the loose mix specimens. Specimens were
tested under theWTAT. Hydrated lime was utilized as the antistripping agent.
It is concluded that if hydrated lime is utilized as an additives, not only stripping is reduced
but also the stability and durability of the asphalt pavement is increased. The presented
approach ultimately resulted in improving mix properties.
