Abstract:

This paper proposes the use of tablet's built-in accelerometers to estimate a roughness index able to capture pavement roughness condition. Several experiments were conducted in mud, gravel, chip-sealed and paved roads at different speeds and with different vehicles. Approximately 300km of roads in the province El Oro (Ecuador) were visited as part of the testing. It was confirmed that standard deviation of vertical accelerations normalized by speed -in meters per second- was able to produce a roughness indicator useful to assess surface condition. A comparison between two common tablet platforms found differences that could be explained by frequency of data collection, travelled path and influence of x,y accelerations in z-accelerations. Speed-normalized standard deviations of vertical accelerations were found to respond largely to the number of observations collected per second. An experiment with different vehicle sizes showed the impact of the suspension system. A protocol for data collection is given. It is expected that governments unable to purchase laser profilometers can make use of this approach to obtain a proxy for the International Roughness Index and therefore be in capacity to develop performance models and implement a pavement management system.
