In November 2003 the Road Pavement Forum resolved that a technical working group should be formed to investigate the development of a national guideline (or code of practice) on the use of Asphalt Reinforcement. For the purpose of this study the main functions of Asphalt Reinforcement Interlayer (ARI) is to:prevent or reduce reflective cracking from underlying layers,protect asphalt layers against traffic induced cracking,avoid or reduce development of rutting in asphalt layers. Currently there is a large amount of research being carried out in this field, but there has been very little effective dissemination of the best practice and research results.
