Book Description
The material used for subgrade or embankment construction are variable in color, texture and density-moisture relationship. To adequately control the compaction and field densities of these materials is necessary to know what to expect of the material being use. This field book provides you with some information that will serve this purpose. Soil testing is a quantitative method of quality control for the compacted fill material, and the actual number and types made will depend on the requirements specified by the Designer. The Texas Department of Transportation established those requirements on a document called Schedule for Testing and Sampling. Soil testing should always be specified, conducted and the results closely monitored by the designer, inspector and contractor This field book is used precisely, to collect information on site to fully understand the nature of the material that is being use on the project and to demonstrate that the compacted fill is meeting with soils properties, densities-moisture relationship and number of testing required. Closely monitoring the information collected on this field book will give the user valuable information that will allow him to properly manipulate the material being processed This field book is a training tool that aggregates civil engineering and construction knowledge that is considered fundamental during the execution of the earthwork

Book Description
The Dynamic Cone Penetrometer (DCP) is a device that is used for the estimation of in situ compaction quality of constructed subgrades and embankments. It is a relatively inexpensive, light-weight and easy to use device that measures the dynamic penetration resistance of the compacted soil, from which an estimate of soil strength and stiffness characteristics can be made. Owing to its ease of use, many DOTs in the U.S. have employed the DCP in their compaction quality control procedures, and over the past few decades, extensive research has been carried out on the development of correlations between the results of the DCP test and the results of strength and stiffness tests performed on compacted soils (e.g., California bearing ratio, and resilient modulus)The objectives of this research are to refine DCP-based quality assurance and quality control correlations for compaction quality control developed by previous research studies carried out at Purdue for the Indiana Department of Transportation, especially focusing on (1) grouping of the soils based on their mechanical response to the DCP loading, and (2) limiting the in situ moisture range of the soils used for development of correlations within -2% of the optimum moisture content of the tested soil. The factors outlined above are studied, and in particular, soil grouping is examined critically. The AASHTO ('A-based') classification employed previously for classification of soils is replaced with a new classification criteria specifically developed for the DCP test. Soils are grouped into one of the two categories of coarse-grained or fine-grained soils on the basis of the size of the dominant particle in the soil. The criteria developed for the classification of soil into one of these two categories is based on index properties of the soil, such as the standard Proctor maximum dry density, optimum moisture content, plasticity index (PI) and fines content.

Book Description
Annotation Presents 22 papers, from the July 1999 symposium, written on the use of various standardized methods for specifying and controlling the compaction of soil for engineered constructed earth fills. Perspectives include the historical background, current state-of-the- art practices, case histories of challenging situations, concerns regarding appropriate design parameters for compaction control, and new methods to evaluate soil compaction and related qualities.
