Abstract

The aim of this investigation was to study the effects of stripping of a binder from an aggregate due to environmental factors such as temperature and water. Field trials were conducted using mixes with and without anti-stripping additives. Cores were obtained from the trial sections and tested for their Marshall properties. Fresh samples were collected at the site and remolded into standard Marshall samples. The remolded samples were soaked in water at 60 degree C and also at temperatures ranging from 28 to 36 degree C for various time periods and were then tested for their Marshall properties. The results showed that the additive-treated mix was more compactible than the normal mix. The retained stability of the treated samples was much higher than that of the normal mix. The results indicated that the anti-stripping additives resisted attack by water and temperature, thereby reducing stripping.
