Pavement preservation : Cape Seal treatments

The Cape Seal technique has the dual quality of reinstating and rehabilitating pavement surfaces. It was invented in South Africa (in Capetown, which explains its name) and originally consisted of a chip seal that was covered several weeks later by a slurry seal. It is extremely widely used throughout the world, particularly in the United States. This technique aroused the interest of Colas’s French subsidiaries, and the company’s Scientific and Technical Campus (CST) has modified it to suit the French context in terms of traffic conditions, climate, binders and aggregate. A number of experimental projects have been run, culminating in the validation of a two-layer system that is perfectly suited to the maintenance and repair of French pavements, i.e. a chip seal that is covered by a microsurfacing less than 48 hours later.
