This report is the first technical report of Task 5 "Investigation of Existing Roads" in the EU REFLEX project. REFLEX is the acronym for "Reinforcement of Flexible Road Structures with Steel Fabrics to Prolong Service Life". The main objective of REFLEX is to develop a new technology for road construction and rehabilitation. The idea is to use steel fabric reinforcement in asphalt roads in order to make road structures more cost effective by improving the lifetime of new constructed roads and by developing an optimal rehabilitation method for existing roads. Objectives of Task 5, "Investigation of Existing Roads" is to quickly gain practical answers on the effect of steel reinforced pavements compared to the behaviour of unreinforced road pavements. The work is carried out by investigations on reinforced roads that were built during the last ten years. This report covers result of the first part of these investigations.
