Paving is responsible for providing users with trafficability, rolling comfort and safety, its performance tends to deteriorate after the start of rolling, making timely maintenance necessary. It is in this context that the Pavement Management System is established, a coordinated set of activities with the objective of optimizing resources and guaranteeing the quality of the road network. Two concepts are important for the PMS: usefulness, the pavement's ability to provide comfort and performance, and the temporal variation of serviceability. These parameters can be determined according to structural and functional aspects. Associated with thislatter is the Subjective Assessment, addressed in this work, whose objective is to establish the usefulness level of a given pavement through the Current Useful Value, following criteria related to rolling comfort. Due to its subjective aspect, the assessment is subject to interference from factors that are not directly linked to the quality of the pavement, such as the position of the evaluators in the vehicle and the speed of travel. The first being the object of this work, whose results indicate that the feeling of comfort inside a vehicle varies according to the position occupied, and tends to fluctuate more intensely the worse the condition of the pavement is.
