Book Description
Sand compaction piles can be used to improve marginal sites for stability, liquefaction, and settlement applications. They have been employed extensively in Japan for many years to improve land reclaimed from the sea. The advantages and disadvantages of using sand compaction piles are compared with other vibro-compaction techniques such as stone columns. Methods are described for construction of sand compaction piles on land and over water. Design theories are given for the utilization of sand compaction piles at sites underlain by both cohesionless and cohesive soils. For sites underlain by cohesionless sands, procedures are presented for estimating the increase in standard penetration resistance in both the sand compaction pile and the surrounding sand. Techniques are described for estimating stability and one-dimensional consolidation settlement of sites underlain by cohesive soils that have been improved with sand compaction piles. Finally, typical applications of sand compaction piles are described, and practical design criteria and practices are given. Keywords: In-situ deep compaction, Liquefaction, Pore water pressure, Remedial treatments, Soils, Pool reinforcements.

Book Description
The Sand Compaction Pile or (SCP) method is used frequently in construction to form compacted sand piles by vibration, dynamic impact or static excitation in soft ground. Originally developed in Japan to improve stability or compressibility and to prevent liquefaction failure in loose sand, the SCP method is now often applied to soft clay ground to ensure stability and reduce ground settlement. This book presents detailed descriptions of design, execution, quality control, equipment and assurance aspects of the SCP method, illustrating the theory with case studies from around Japan and also including a thorough overview of the existing literature on research and development carried out since the 1950s. Two final chapters cover vital aspects of design procedures for clay and sandy ground to enable practitioners to frame an appropriate set of parameters for durable and cost-efficient design.

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.
