Abstract

       This study aims to investigate the measurement of flexible pavement overlay design using Benkelman beam (BB). In this case, pavement deflection, pavement overlay thickness, and pavement usage property parameters that reported from measuring tool. In this study, data of pavement deflection under load was collected. Selected pavements are in asphalt concrete type and under usage. The structure component, appearances, usage lifetime, and layer structure were also investigated. For case study, 10 pavements in central region of Thailand were selected and separated into 27 test section, each range of 2 kilometers. Then, test sections were grouped according to traffic volume, asphalt concrete pavement thickness and service lifetime. Tool used for measuring pavement deflection parameter under load are Benkelman beam (BB), For testing, data of deflection parameter, thickness and type of material in each structure layer, temperature, rut depth, percent of cracking, and traffic volume were collected and analyzed Benkelman beam according to DOH standard to determine the relationship. In this step, statistical programming was used to determine relationship and statistical parameter. Therefore, this design resulted in reduction of construction cost, and the maintenance cost could be reduced.
