Soil Stabilization For Roads And Streets

Developments in Geotechnical Engineering, Volume 19: Stabilized Earth Roads surveys soil stabilization theory and practice. This work is divided into nine chapters that discuss the physical, chemical, and soil mechanics principles of soil stabilization. The first chapter is an introduction to the history, methods, and importance of soil stabilization in road construction. The next chapters deal with the fundamental definitions of soil physics and the interactions of soil components, as well as the concept of mechanical soil stabilization. Considerable chapters examine soil stabilization with several materials, such as cement, lime, bitumen, and tar. The last chapters describe the soil-stabilization methods with various chemicals, including chlorides, phosphoric acid, and natural and synthetic polymers. These chapters also consider the design of stabilized earth roads. This book is of value to geologists and civil engineers.

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.
