IMPORTING FRENCH TECHNOLOGY For the periodic maintenance of National Route 3 Section 1 from Candella Road (km 8.5) to Paradise Valley (km 17.0), in the eThekwini Metropolitan area, it was decided to implement French technology. This would be the first full-scale EME (Enrobé à Module Élevé) construction project in South Africa. EME consists of a low penetration binder (10/20 pen. grade) that is extremely hard, but not brittle, resulting in a very stiff asphalt layer that has good fatigue and rutting resistance. These features make it an excellent alternative to concrete pavements. In addition, the inclusion of 20% RAP (reclaimed asphalt) pushed the boundaries even more, as standard practice in Europe is to only include virgin material.
