A New Device for Compaction Control

Compaction of soil is essential in the constructionof highways, airports, buildings and bridges.Typically compaction is controlled by measuring thedry density and the water content of the compactedsoil. There is a trend towards measuring thesoil modulus instead or in addition to density. Thereasons are that the density measurements are madeusing nuclear density meter, an undesirable tool intoday's political environment and that pavementdesign uses moduli as an input parameter. Althoughthere are many apparatus available to measure soilmodulus in the field such as Falling WeightDeflectometer and Dynamic Cone Penetrometer, a lightweight device which can measure the soil modulusfast and accurately is in great need.This book presents the newly patented BriaudCompaction Device (BCD) which is a portable devicemeasuring soil modulus in several seconds. Theprinciple of the BCD is explained and the validationprocess of BCD is demonstrated in this book. Thisbook should help shed some light on the the field ofcompaction control technologies and should be usefulto professionals in the construction andmanufacturing industry.

Compaction of soil is essential in the construction of highways, airports, buildings and bridges. Typically compaction is controlled by measuring the dry density and the water content of the compacted soil. There is a trend towards measuring the soil modulus instead or in addition to density. The reasons are that the density measurements are made using nuclear density meter, an undesirable tool in today's political environment and that pavement design uses moduli as an input parameter. Although there are many apparatus available to measure soil modulus in the field such as Falling Weight Deflectometer and Dynamic Cone Penetrometer, a light weight device which can measure the soil modulus fast and accurately is in great need. This book presents the newly patented Briaud Compaction Device (BCD) which is a portable device measuring soil modulus in several seconds. The principle of the BCD is explained and the validation process of BCD is demonstrated in this book. This book should help shed some light on the the field of compaction control technologies and should be useful to professionals in the construction and manufacturing industry.
