عنوان مقاله [English]
Evaluation of pavement structure is an important part of the pavement management system at the network and project levels, which is usually performed by using falling weight deflectometer (FWD) device. In using the FWD device, strength of the pavement layers is determined by back-calculations method. Using this method is not financially and temporally affordable for management at network level because of complexity and need for accurate initial information, and therefore it is usually used at the project level. Dynamic cone penetrometer (DCP) is another equipment, which is fast and cheap, and is used in evaluation of pavement structure at network level. In this research, 50 km of arterial road of Kermanshah province was tested by using the FWD and DCP devices. Results showed acceptable correlation between penetration index, as DCP output, and the obtained data of FWD device for pavement layers. The PI variation range for different pavement structure situations at network level was presented by analyzing the FWD and DCP outputs. Output results of network analysis using both methods showed acceptable PI criterion validity as simple and cheap criterion for pavement structure evaluation in pavement management at network level.
