Product Information

Anti stripping agents are the chemical compounds, which renders minimum stripping (breaking) of bonds between the aggregate surface and the bitumen. The stripping is attributed to water which gets between the bitumen film and the aggregate surface. The aggregate surface is having greater attraction to water than for bitumen owing to hydrophilic nature of aggregate. This leads to the breaking of adhesive bond of bitumen to aggregate.

The natural stones aggregate mostly used for road construction and the surface treatment in India generally do not conform to the stripping requirements viz 5% (max) specified by Indian Road Congress.

To achieve good bong between aggregate and bitumen the anti stripping agents are used. The types of anti stripping agents used are Fatty amines and Tallow Diamine, and Fatty amino and Immidazoline derivatives. In literature, it is claimed that the use of anti stripping agents had resulted in a substantially longer lasting asphalt pavement and improved tensile strength saving in maintenance and repair cost from base course to surface mixes.
