This report is the second and final technical report of Task 2"Product Development" in the EU REFLEX project. REFLEX is the acronym for "Reinforcement of Flexible Road Structures with Steel Fabrics to Prolong Service Life". This project is carried out within the EC 4th Framework Programme in BRITE/EURAM 111 of DGXII.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 2, "Product Development" is to investigate and develop the optimum material specification of the steel and configuration of the steel mesh. This report covers results of the first part of the laboratory investigations and gives preliminary recommendations for field experiments and accelerated tests.
