Adhesion Promoters in Action

Improving Pavement's Durability and Life Expectancy

In developed countries, road maintenance or reconstruction are the primary road paving activities. In developing countries, the focus is more on construction of road networks. In both cases, the durability and life expectancy of the asphalt pavement is of vital importance.

The symptoms of water damage on roads and highways include rutting and shoving, loss of chippings from surface dressings (chip seals), bleeding, washing out of fines, and raveling of surface layers leading topotholes.

This type of deterioration is accelerated when the pavement undergoes freeze-thaw cycles; however, the underlying problem on a molecular scale is loss of adhesion between the binder and the aggregate in the presence of water. This is often referred to as stripping.

Nouyon's Solutions 

Wetfix®, Redicote®, Kling Beta® and adhesion promoters create a strong chemical bond between bitumen and aggregate and these bonds are resistant to the action of water which extends the durability of the pavement.

The dosage level of adhesion promoters in asphalt pavement is very low. The additional cost of adding Wetfix®, Redicote®, and Kling Beta® is small compared to the total cost of constructing the pavement. Plus, the extended service life of the asphalt provides big savings in the long run.

Wetfix®, Redicote®, and Kling Beta® products protect asphalt pavements from moisture damage, especially when exposed to frequent rain and freeze thaw cycles, thereby lowering maintenance costs. In several countries, due to extensive testing, trialing and experience, it is mandatory to add adhesion promoters to asphalt mixes.
