Book Description
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF/IIEC Innovation Center This report describes a HITEC evaluation designed to determine the basic capabilites and limitations of the Geo-Con VERT Wall for use as a technically viable permanent excavation support retaining wall system. The evaluation was conducted based on design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The Geo-Con VERT Wall System is an in-situ retaining wall system intended as an alternative to other types of cut walls such as soldier pile and anchored retaining walls. Geo-Con VERT Wall System is comprised of: deep soil mix columns consisting of overlapping or tangent soil-cement columns along the front face backed up by tangent rows of overlapping soil-cement columns; a soil-cement relieving platform overtop the columns; steel beams embedded in the front face soil-cement columns for support of the permanent facing; and permanent facing consisting of precast, reinforced concrete panels or reinforced cast-in-place concrete. The relieving platform is intended to provide internal stability by typing the soil-mix columns together and transferring the load to the bottom of the columns.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 663: Design of Roadside Barrier Systems Placed on MSE Retaining Walls explores a design procedure for roadside barrier systems mounted on the edge of a mechanically stabilized earth (MSE) wall. The procedures were developed following American Association of State Highway and Transportation Officials Load and Resistant Factor Design (LRFD) practices. Appendices A through H to NCHRP Report 663 are available online. Titles of Appendices A through H are as follows: Appendix A: Design of MSE Wall; Appendix B: State-of-Practice Survey; Appendix C: Detailed Drawing of MSE Wall for Bogie Test; Appendix D: Bogie Test MSE Wall Construction Procedure; Appendix E: Detailed Drawing of MSE Wall for TL-3 Test; Appendix F: TL-3 MSE Wall Construction Procedure; Appendix G: Crash Test Vehicle Properties and Information; Appendix H: Crash Test Sequential Photographs--

Book Description
Characterisation of the shallow subsurface provides civil, geotechnical and environmental applications with precise definitions of geomechanical and geohydrological properties. Over the past decade, the rapid pace of technological innovation has outstripped the ability of many researchers and potential users to evaluate and adopt promising new characterisation methods. Modern information technologies and information management concepts provide the basis of new paradigms and applications. This book defines future research needs for geological modelling and ground characterisation, including better dialogue between data provides and users and faster, better and less expensive methods for the creation and dissemination of subsurface characterisations.

Book Description
This document presents state-of-the-practice information on the evaluation of soil and rock properties for geotechnical design applications. This document addresses the entire range of materials potentially encountered in highway engineering practice, from soft clay to intact rock and variations of materials that fall between these two extremes. Information is presented on parameters measured, evaluation of data quality, and interpretation of properties for conventional soil and rock laboratory testing, as well as in situ devices such as field vane testing, cone penetration testing, dilatometer, pressuremeter, and borehole jack. This document provides the design engineer with information that can be used to develop a rationale for accepting or rejecting data and for resolving inconsistencies between data provided by different laboratories and field tests. This document also includes information on: (1) the use of Geographical Information Systems (GIS) and Personal Data Assistance devices for the collection and interpretation of subsurface information; (2) quantitative measures for evaluating disturbance of laboratory soil samples; and (3) the use of measurements from geophysical testing techniques to obtain information on the modulus of soil. Also included are chapters on evaluating properties of special soil materials (e.g., loess, cemented sands, peats and organic soils, etc.) and the use of statistical information in evaluating anomalous data and obtaining design values for soil and rock properties. An appendix of three detailed soil and rock property selection examples is provided which illustrate the application of the methods described in the document.

Book Description
This book gathers the latest research, innovations, and applications in the field of civil engineering, as presented by leading national and international academics, researchers, engineers, and postgraduate students at the AWAM International Conference on Civil Engineering 2019 (AICCE’19), held in Penang, Malaysia on August 21-22, 2019. The book covers highly diverse topics in the main fields of civil engineering, including structural and earthquake engineering, environmental engineering, geotechnical engineering, highway and transportation engineering, water resources engineering, and geomatic and construction management. In line with the conference theme, “Transforming the Nation for a Sustainable Tomorrow”, which relates to the United Nations’ 17 Global Goals for Sustainable Development, it highlights important elements in the planning and development stages to establish design standards beneficial to the environment and its surroundings. The contributions introduce numerous exciting ideas that spur novel research directions and foster multidisciplinary collaborations between various specialists in the field of civil engineering.
