Soil and Rock Description in Engineering Practice

xvi, 288 pages : illustrations (some colour. The procedures, techniques and tips within this book are not only for young practitioners learning their craft, but are also relevant for their seniors and mentors, including responsible experts who sign off the logs and report on behalf of their company. Although they may have been involved in logging for many years they need to be aware of current practices in order to avoid costly mistakes. Soil and Rock Description in Engineering Practice enables the practitioner to record and present features of the ground from the exposure in such a way as to convey a field presence to subsequent users of the data. This is important as the samples deteriorate quickly and are not usually inspected by any party other than the logger. Field logs therefore provide the only record of the ground that is available to the designer and contractor later in the construction process. The procedures given are in accordance with the newly-implemented ISO, EN and BS international standards and other practice such as ASTM is also considered. The rules set out in these standards are considerably amplified by the author's 35 years experience describing natural and anthropogenic materials in the field and in teaching others to do so.…
