Soil rutting prediction using Random Forest model
Soil rutting in forest operations is a critical phenomenon, characterized by depressions or tracks on the forest floor, often caused by heavy machinery use such as logging equipment. These disturbances can have profound impacts on forest health and ecosystem integrity, disrupting soil structure, …

Evaluation of binder grades on rutting performance
… mixes that have a good history of resisting rutting in posted speed applications may not perform well in intersections, climbing lanes, truck weigh stations, and other slow speed areas. The West Virginia Division of Highways, WVDOH, has implemented the Performance Grade binder specifications …

Evaluation of indirect tensile strength to identify asphalt concrete rutting potential
… the development of a simple performance test for rutting potential of asphalt mixtures. Anderson et al. [2003] found that rutting potential can be evaluated by considering indirect tensile strength (IDT), compaction slope measured with the Superpave Gyratory compactor and voids in mineral …

Permanent deformation behavior of unbound granular materials and rutting model development
The rutting damage model as incorporated into the AASHTO’s mechanistic-empirical (M-E) pavement design approaches (i.e. Pavement ME Design) was found to produce inadequate rut estimates in unbound aggregate base/subbase layers by discounting the contribution of stress state from the original Tseng …

Influence of Recycled Asphalt Shingles on Asphalt Binder Content, Mixture Stiffness, and Laboratory Rutting Performance
… content, mixture stiffness, and laboratory rutting performance. For this project, shingles were added to hot mix asphalt mixtures at 2.5, 5, and 10 percent by weight of the total mix. This study showed that incorporating shingles into mixes is sometimes complex due to the interaction of a …

Development and validation of a novel testing procedure for the evaluation of rutting susceptibility of bituminous binders.
… reported herein deals with evaluation of rutting susceptibility of different asphalt binders thorough various parameters and correlating them with parameters resulted from tests carried out on their corresponding mixtures. Several factors influence the occurrence of rutting in asphalt …

Use of the Clegg Impact Soil Tester to Access Rutting Susceptiblity of Cement-Treated Base Material Under Early Trafficking
… gain has occurred can lead to marring or rutting of the treated layer. The specific objectives of this research were to examine the correlation between Clegg impact values (CIVs) determined using a heavy Clegg impact soil tester and rut depths measured in newly constructed CTB and …

Analyses and prediction of granular layer rutting trends in airport pavements due to heavy aircraft wheel loading and wander patterns
… all the available sections, the contribution of rutting from the rather thick subbase layers (34 and 38 in.) were significant when compared to those of the other layers. Furthermore, accumulations of permanent deformation in subbase layers did not slow down but rather increased as traffic …

Flexible Pavement Rut Depth Modeling For Different Climate Zones
<p>Pavement rutting is one of the most important types of pavement distress that affect road safety and ride quality. Therefore, the primary objective of this study was to develop pavement rutting empirical models for different climate zones to predict pavement rutting on granular base based on …

Performance of hot mix asphalt using peat modified asphalt binder
… weight peat substructure. Based on the SHRP rutting parameters, adding PNpt decreases rutting for the binder at high temperature rheological properties indicated that 5% PNpt or PNpt.M.A. 5 is the optimum content as a modifier with asphalt. After the optimum content of PNpt, tests were …

Evaluation and modeling of repeated load test data of asphalt concrete for mechanistic-empirical flexible pavement design
… Dynamic Modulus (DM) as a factor in predicting rutting performance of asphalt concrete. The rutting model is empirical and the rutting profiles obtained from the model are largely based on the adjustment of calibration constants not the DM. Various DM values would be capable of producing similar …

Balanced Mix Design of Asphalt Mixtures for Intersections
Rutting and shoving are the most common distresses found at intersections. Realizing the need for different asphalt mixtures at or near intersections, a past cooperative research between University of Nevada, Reno (UNR) and Nevada Department of Transportation (NDOT) recommended a new gradation …
