PURPOSES: The objective of this study is to investigate the current state of the practice, examining the steps in the process recommended by various agencies and the Asphalt Recycling and Reclaiming Association (ARRA)-namely mix design, structural design, structural capacity evaluation, and material characterization-in order to better understand the implications of hot in-place recycling (HIR). METHODS: In addition, the current practice of state departments of transportation (DOTs) is here reviewed with the purpose of learning from successful past experiences so as to forestall any difficulties that may emerge under similar circumstances. Also, HIR benefits, including reduced costs, improved construction processes, and environmental friendliness are presented, as well as advantages and disadvantages of HIR application. RESULTS: Most of the United States highway system is now deteriorating so that rehabilitation or reconstruction techniques are required for the most distressed roads, taking into account ways to increase the effectiveness of existing budgets. Several options are available in rehabilitating distressed roads, and the choice among these depends on many factors, including pavement distress condition, funding, and design life. Among these techniques, Hot In-Place Recycling (HIR) has emerged as a cost-effective treatment for deteriorated pavements, and has been proven an effective long-term strategy for pavement rehabilitation.
