Accelerated Pavement Testing Experiment of a Pavement Made of Fiber-Reinforced Roller-Compacted Concrete

Within the framework of the French National Research Agency (ANR), the project “Recyroute” aims to investigate the use of Fiber-reinforced Roller-Compacted Concrete (FRCC®) mixed with Reclaimed Asphalt Pavement (RAP) for heavy traffic road pavements. It comprises an accelerated pavement test conducted by means of the Accelerated Pavement Testing (APT) facility at IFSTTAR. Eight different structures were tested, including a reference section constructed with bituminous material, one structure constructed with ERTALH® gravel (RAP aggregate treated with hydraulic binder), and six other structures constructed with FRCC® materials. An associated laboratory test program was carried out to determine the mechanical properties of ERTALH® and FRCC® materials with respect to pavement design applications. This paper presents the main features and results of this APT experiment and the associated laboratory tests, leading to propose practical parameters for the thickness design of these innovative pavement structures, according to the French rational pavement design method.
