The DOH (Department of Highways) in Thailand specifies the use of slow setting grades of asphalt emulsion excluding cutbacks for prime coats. Picture courtesy of Nouryon

The Emulsion Asphalt Prime (EAP), prime coat application in Thailand

The benefits of prime coat are to enhance aggregate’s cohesion of road base course resulting in no surface damage prior to paving and to prevent water penetration through the base course prior to paving. This technique is commonly performed with emulsions and used worldwide to provide a bond between the base course and asphalt layer.

Vietnam, with only 20 per cent of the country’s national roads paved, has approved $14bn plan to build a 1372 km highway by 2030. Picture courtesy of Nouryon.

Use of adhesion promoters to extend the life of asphalt pavements in Vietnam

Moisture damage to asphalt pavements is a major issue since bitumen does not have a natural affinity to siliceous aggregates and most of the aggregates used for paving contain silica as a main component.
