Soil moisture is an important indicator of constructability in the field. Construction activities become difficult when the soil moisture content is excessive, especially in fine-grained soils. Change orders caused by excessive soil moisture during construction projects drive up construction costs for INDOT and cause unexpected delays. To alleviate these problems and minimize change order costs associated with unexpectedly high soil moisture conditions at the time of construction, a methodology was developed to allow INDOT engineers to estimate in situ soil moisture conditions early in the design phases of projects. The soil moisture prediction methodology is based on results from soil moisture flow simulations carried out using the HYDRUS-1D software. The soil moisture flow simulations in HYDRUS-1D required i) weather data, ii) groundwater table data and iii) in situ soil hydraulic (saturated and unsaturated) and index property data. These data were collected for all the counties in Indiana from five different sources: i) Indiana Department of Transportation (INDOT), ii) Indiana Geological Survey (IGS), iii) United States Department of Agriculture's (USDA's) Soil Survey Geographic (SSURGO), iv) the Department of Natural Resources (DNR) and v) Indiana State Climate Office (Iclimate). The results obtained from initial soil moisture flow simulations were first validated using field measurements from six IGS test sites located in Indiana where soil property data and continuous in situ soil moisture measurements at multiple depths were available for up to 3 years (2011-2014). Then, ten-year moisture content simulations using HYDRUS 1D were performed for typical profiles in each county in Indiana using as input weather data from the iclimate database, groundwater data from DNR database and soil properties from IGS, INDOT and the SSURGO databases. Yearly results from these ten-year soil moisture flow simulations were then overlapped to ascertain how the profiles of the in situ soil moisture content within the depth of interest varied monthly within this period of time in each county. Recommendations are made for in situ soil moisture constructability assessment that can be implemented by INDOT in pilot projects and further refined as needed.

The completely revised and extended Recommendations deal with all questions relevant to the planning and dimensioning of geosynthetics-reinforced earth structures. In addition to the demands on materials and analysis principles, the applications of geosynthetics in a range of foundation systems, ground improvement measures, highways engineering projects, in slopes and retaining structures, and in landfill engineering are discussed. The Recommendations have been supplemented by the following sections: - reinforced earth structures over point or linear bearing elements, - foundation systems using geotextile-encased columns, - bridging subsidence, - dynamic actions of geosynthetic-reinforced systems. The remaining sections have been fundamentally revised and updated in line with current standards and codes of practice.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 338: Thin and Ultra-Thin Whitetopping summarizes available information to document how state departments of transportation and others are currently using thin and ultra-thin whitetopping overlays among various pavement rehabilitation alternatives. The report covers all stages of the proper application of whitetopping overlays, including project selection, design, materials selection, construction, maintenance, and eventual rehabilitation or replacement.

Great strides have been made in the art of foundation design during the last two decades. In situ testing, site improvement techniques, the use of geogrids in the design of retaining walls, modified ACI codes, and ground deformation modeling using finite elements are but a few of the developments that have significantly advanced foundation engineering in recent years. What has been lacking, however, is a comprehensive reference for foundation engineers that incorporates these state-of-the-art concepts and techniques. The Foundation Engineering Handbook fills that void. It presents both classical and state-of-the-art design and analysis techniques for earthen structures, and covers basic soil mechanics and soil and groundwater modeling concepts along with the latest research results. It addresses isolated and shallow footings, retaining structures, and modern methods of pile construction monitoring, as well as stability analysis and ground improvement methods. The handbook also covers reliability-based design and LRFD (Load Resistance Factor Design)-concepts not addressed in most foundation engineering texts. Easy-to-follow numerical design examples illustrate each technique. Along with its unique, comprehensive coverage, the clear, concise discussions and logical organization of The Foundation Engineering Handbook make it the one quick reference every practitioner and student in the field needs.

Full-depth reclamation (FDR) is a roadway rehabilitation process that recycles the materials from deteriorated asphalt pavement, and, with the addition of portland cement, creates a new stabilized base. This guide to FDR discusses its applications, benefits, design, construction, and testing.
