• W636502175 abstract "In this paper, a new roughness index called the Dynamic Load Index (DLI) is developed for the purpose of identifying pavement profiles that are likely to generate high dynamic truck-axle loads. The DLI is calculated as a weighted index of variances of the profile elevation in the frequency ranges 1.5-4 Hz and 8-15 Hz. The first frequency range corresponds to body bounce, while the second frequency range corresponds to axle bounce. The analysis showed a very good relationship between DLI and dynamic load. The DLI was tested on a range of road profiles from in-service pavements, and it was found that for any particular value of quality index (RQI), the DLI can cover a wide range of values, and this variation in DLI was found to correlate very well with dynamic load, as predicted by a simulation program. This was not the case for the International Roughness Index ORI), which gave a low coefficient of correlation with dynamic load for the same range of profiles. Therefore, the new index can differentiate between profiles that generate high dynamic loads and those having the same RQI but generating low dynamic loads. Most importantly, the use of the DLI index negates the need for running a simulation program. This makes it possible for a state highway agency to decide whether a particular pavement with a given surface profile needs smoothing (to extend its service life) based on the DLI-value. INTRODUCTION A number of profile indices have been developed for characterizing pavement surface roughness in terms of serviceability or quality. Such indices include ride numbers such as the Ride Quality Index used by the Michigan department of Transportation (MDOT). The most used roughness index is the International Roughness Index (IRI). All of these indices are based on the response of passenger cars to the pavement profile. While they can generally have a good correlation with dynamic loading, these indices are not able to determine whether a specific pavement section is truck friendly or not. This makes it difficult to decide whether or not a particular pavement section should be smoothed based on such indices because damage in pavements is caused mainly by heavy axle loads. An accurate prediction of roughness level that will excite trucks requires the evaluation of dynamic axle loading likely to be generated by the profile characteristics of the individual pavement section. One way to predict dynamic axle loads, given a surface profile, is to use a simulation computer program. This would require some knowledge of dynamics and a minimum fluency in parameters for specific components such as the suspension system, the chassis and the tires. Therefore it would be impractical for a state highway agency such as MOOT to adopt such an approach. An alternative method would be to determine the relative increase in dynamic axle loads directly from the profile itself, since dynamic axle loading is a function of the pavement surface profile characteristics. In this paper, a new roughness index termed the Dynamic Load Index (DLI) is developed. This new index negates the need for running a simulation program to determine whether a pavement profile is friendly/unfriendly from a dynamic loading aspect. The DLI can be a useful pavement management tool since it makes it possible to decide whether a particular pavement with a given surface profile needs smoothing for the purpose of reducing dynamic truck-axle loads and preventing accelerated pavement damage. BACKGROUND The Michigan DOT has funded a research study to develop roughness thresholds aimed at minimizing dynamic truck-axle loads (1). Because MOOT uses the RQI as its roughness index, it was decided to first investigate the feasibility of using RQI for developing these thresholds." @default.
