Increasing traffic puts higher demands on construction and maintenance of pavements. To minimize hindrance for the road-user, a high quality durable pavement must be realized in short available time. The Dutch Ministry of Transport, Public Works and Water Management is working on smart and efficient use of infrastructure. Their pilot project Modular Road Surface aimed at a prefabricated road with a high noise reduction that could be constructed and replaced quickly. To address this topic a prefabricated asphalt wearing course was developed by a consortium of Dura Vermeer and Intron. This Rollpave concept consists of a prefabricated thin asphalt layer that can be unrolled like a carpet. This layer can be bonded very quickly by an innovative bonding system based on electromagnetic waves. Rollpave has been realized on three test sections on motorways A35 and A37 with an average length of 450 metres and width of 12 metres. Typical dimension of one asphaltmat is 50 metres by 3.75 metres. An extensive testing program has been carried out on all three test sections. It has been shown that it is possible to create a safe prefab road for motorways. The speed of construction needs to be improved. The concept is rather independent of the weather conditions; one test section has even been constructed while freezing. The noise reduction of Rollpave is better than single-layer porous asphalt and approaches the performance of two-layer porous asphalt. The paper will focus on the Rollpave concept and the results of the three test sections.
