Book Description
This investigation was initiated to review the current engineering literature and synthesize from it a design procedure for stabilizing expansive soils beneath airport pavements. To do this, the study was broken down into six specific areas: (1) Methods of identifying and classifying the types of soil that are considered expansive and cause early pavement distress; (2) Laboratory and/or field test methods to determine the level of expansion and shrinkage; (3) Selection of the type and amount of stabilizing agent (lime, cement, asphalt, only); (4) Test methods to determine the physical properties of stabilized soil; (5) Test methods to determine the durability of stabilized soil; and, (6) Field construction criteria and procedures. This report addresses the above objectives and provides a summary of the current literature pertaining to the subject. Conclusions and recommendations were made based on the current literature, without laboratory verification. Soil volume changes caused by other factors (e.g., frost heave, salt heave) were not studied.

Book Description
Essential technical information for building on expansive soils--complete with practical, proven design methods. Expansive Soils examines factors that influence the design offoundations and pavements built on expansive soils, and exploreskey design procedures and remedial measures that address thesefactors effectively. Backed by the authors' extensive research andexperience --including interviews with practicing engineers workingwith expansive soils --this authoritative volume is an importantreference text for geotechnical and foundation engineers,geologists, construction professionals, and students. Easy to understand and apply, Expansive Soils contains: * Site investigation techniques for identification andclassification of expansive soils * Heave prediction methods using different types of data --withrigorous treatment of soil suction theory and measurement,oedometer tests, and more * Alternative design procedures for drilled pier and slab-on-gradefoundations, highway and airfield pavements * Treatment and chemical stabilization techniques --including salttreatment; moisture barriers; lime and cement stabilization; andother procedures * Remedial measures such as drainage control, and removal withreplacement and compaction control * Sample problems illustrating practical applications.

Book Description
This report documents site investigations and design recommendations for airport pavements on expansive soils at three sites. The methods used were developed previously in an FAA-sponsored research project. The design procedure involves soil characterization, determination of surface characteristics and evaluation of soil-pavement interaction. Investigations at three airports are reported; they are Murdo, South Dakota, Mesquite, Texas, and Love Field, Dallas, Texas. Soils data are used along with climatic information to obtain estimates of the equivalent thickness of pavement required for each site. The work at Love Field was somewhat different than the other sites since NMERI Was not directly conducting the investigation. Results are reported in the form of pavement thickness required to adequately perform, in terms of surface roughness, on the soil surface characteristics predicted fo reach site. Recommendations are included for consideration in rehabilitation of each site since all were experiencing surface roughness at the time of the investigations. These results confirm that methods developed for evaluating airport pavements on expansive soils provide useful information for pavement design. This method specifically addresses the expansive soil problem and does not address the effects of traffic or load-induced pavement distress. These aspects are believed to be adequately covered in standard FAA design procedures. Keywords: Thermocouple psychrometer; Roughness; Filter paper.
