Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
Iowa features an extensive surface transportation system, with more than 110,000 miles of roadway, most of which is under the jurisdiction of local agencies. Given that Iowa is a lower-population state, most of this mileage is located in rural areas that exhibit low traffic volumes of less than 400 vehicles per day. However, these low-volume rural roads also account for about half of all recorded traffic crashes in Iowa, including a high percentage of fatal and major injury crashes. This study was undertaken to examine these crashes, identify major contributing causes, and develop low-cost strategies for reducing the incidence of these crashes. Iowa's extensive crash and roadway system databases were utilized to obtain needed data. Using descriptive statistics, a test of proportions, and crash modeling, various classes of rural secondary roads were compared to similar state of Iowa controlled roads in crash frequency, severity, density, and rate for numerous selected factors that could contribute to crashes. The results of this study allowed the drawing of conclusions as to common contributing factors for crashes on low-volume rural roads, both paved and unpaved. Due to identified higher crash statistics, particular interest was drawn to unpaved rural roads with traffic volumes greater that 100 vehicles per day. Recommendations for addressing these crashes with low-cost mitigation are also included. Because of the isolated nature of traffic crashes on low-volume roads, a systemic or mass action approach to safety mitigation was recommended for an identified subset of the entire system. In addition, future development of a reliable crash prediction model is described.

Book Description
A primary purpose of this report is to review and summarize studies that provided comparative data on the impacts of paved roads and unpaved roads for selected environmental factors. The results of the literature search suggest that comparative studies of the impacts of paved versus unpaved roads are not well documented for a broad range of environmental impacts. Dust impacts of unpaved roads on air quality, water quality, aquatic habitat, and the effectiveness of dust control and suppression measures, including paving, are well documented and provide a basis for making comparisons. Little comparative information on the other environmental factors considered for this report was found. A literature review, surveys, and data analyses indicate that paving gravel roads may raise property values and vehicle speed. Paving has little effect on traffic volume, economic development, employment, tourism and recreation. Evidence from testing an empirical model suggests that paving may reduce fatal accident rates. However, this finding may also be attributable to safety improvements which often accompany paving rather than the paving itself. Because there are a number of plausible explanations for this finding, the issue should receive further study.
