• Modeling the Impact of Energy Trafficon Local Unpaved Roads
  Abstract: Laramie County was selected in accordance with the legislative directive as part of a project to determine the impact of the oil and gas industry on county roads. This paper takes into account the impact gravel roads. With a lacking road and bridge budget, Laramie county is only just keeping up with this impact. In order to receive additional funding from the state legislature, actual impact needs to be assessed. The different distresses and ride quality of all the county gravel roads showed that, on average, the roads were in good condition, no matter the level of impact. However, the cost to keep the impacted roads in this condition came at a much greater price. By modeling the characteristics of the gravel roads in Laramie County, a better understanding of the degradation taking place and the main causes were examined. This was done in hopes that the information from this model will then be used for more efficient maintenance strategies and a more cost effective use of the county’s budget so that the county may continue to keep up with the energy impact. The processed developed in this study is very useful for other local agencies impacted by energy development.

• Methodology to Characterize Agriculture-Related Trucking on Low-Volume Rural Roads to Support Asset Management
  Abstract: This paper develops a methodology to characterize agriculture-related trucking on low-volume rural roads. The methodology considers truck trips from the field to intermediate storage facilities (field-to-storage) and from these facilities to market (storage-to-market). The methodology, which applies the transportation systems analysis approach, leverages knowledge from local producers through in-person interviews to qualitatively and quantitatively characterize the transportation supply and demand that generate truck flows. Flow characterization in terms of truck volumes and trip-making characteristics supports asset management decisions, such as maintenance timing and upgrade investments, in addition to providing information for forecasting future demand and infrastructure impacts.The development and application of the methodology contributes in three ways. First, it characterizes truck flows from field-to-storage, a segment of the agricultural supply chain seldom considered by previous research. Second, it demonstrates the extent of information concerning road usage and impacts available from producers. Third, results from the application of the methodology to a study region in Manitoba reveal that: (a) smaller truck types are more commonly used for the shorter field-to-storage trips than storage-to-market trips; (b) actual distance traveled exceeds desired distance traveled, owing mainly to infrastructure-related regulatory constraints; and (c) trip length distributions for the storage-to-market segment exhibit a relationship between trip length and type of truck and commodity. The methodology is transferrable across jurisdictions and scalable for different geographic and temporal scopes. The specific results presented in this paper, however, may not be representative of conditions in other regions.

• Validating Spring Weight Restriction Limits on Low-Volume Roads in Manitoba Using Mechanistic-Empirical Failure Prediction Models
  Abstract: This study developed local mechanistic-empirical failure models to predict fatigue and rutting damage on spring weight restricted (SWR) roads in Manitoba. The local models were used to assess the SWR load limits and to validate the current SWR deflection levels that regulate commercial vehicle weights during the spring period. The local model predictions were compared to the Asphalt Institute and Mechanistic Empirical Design Guide (MEPDG) damage models. The results of the damage analysis are presented.
