    Many public agencies rely on heavy duty diesel equipment to perform highway maintenance activities. This equipment consumes large quantities of diesel fuel and consequently emits substantial amounts of air pollution, thus posing a significant energy and environmental impact for the nation. In hopes of minimizing these impacts, some public fleet owners have turned to biodiesel as an alternative to traditional diesel fuel to reduce petroleum consumption as well as air pollutant emissions. The primary goal of this paper is to present real world HDD equipment fuel use rates and emission rates of nitrogen oxides, hydrocarbons, particulate matter, carbon monoxide, and carbon dioxide. These fuel use and emissions rates were based on second-by-second data collected by a portable emissions measurement system from five backhoes, six motor graders, and four wheel loaders as they performed real world activities. The primary output of this paper is a dataset of real world fuel use and emissions rates that are categorized by pollutant type, equipment type, EPA Engine Tier standards, and fuel type (including conventional petroleum diesel and B20 biodiesel). The intended purpose of this dataset is for public fleet owners to use it as a benchmark for comparison to their own equipment fuel use and emissions performance in order to make informed decisions regarding the energy and environmental impacts of their fleets.
