File: PDF 11.7MB, 266 Pages
Book Description:
Taken from Introduction: This handbook, an updated version of the original Layman’s Handbook on how to develop a Small Hydro Site, published by the Commission in 1993, has been written, in the frame of the ALTENER programme, under contract with the Commission of the European Communities (Directorate General for Energy, DG XVII). It has not been designed to replace professional expertise but it is hoped it is comprehensive enough to advise laymen on all necessary procedures that should be followed to develop a site. However its content includes enough technical information, so a non-specialist engineer would be able to produce a primary feasibility report.

This document serves as the Reference Manual for the 1½-day FHWA workshop on concrete pavement preservation. The purpose of the document is to provide the most up-to-date information available on the design, construction, and selection of cost-effective concrete pavement preservation strategies. It concentrates primarily on strategies and methods that are applicable at the project level, and not at the network level, where pavement management activities function and address such issues as prioritizing and budgeting.
Detailed information is presented on seven specific concrete pavement preservation treatments: slab stabilization, partial depth repairs, full-depth repairs, retrofitted edge drains, load transfer restoration, diamond grinding, and joint resealing. In addition, information is provided on pavement evaluation techniques and strategy selection procedures.

Integrated Materials and Construction Practices for Concrete Pavement
Library of Congress Catalog Card Number: 2006936814
ISBN: 978-0-9652310-9-1
File Format: PDF - 355 pages (high quality) - 18 Mb file size
This manual provides a ready reference and/or instruction guide for anyone involved in designing or constructing concrete pavements. The emphasis is on the concrete material itself—specifically, on optimizing concrete’s performance. To optimize concrete’s performance in today’s pavement construction environment, everyone in concrete paving projects must understand concrete as the central component of a complex, integrated pavement system.
Readers will find some overlap and repetition of information among the chapters. This is a result of the integrated nature of the various stages and considerations involved in designing and constructing concrete pavement projects.

GL2326-Numerical simulation of the response of sandy soils treated with pre-fabricated vertical drains
ARTICLE
2009, Vytiniotis, Antonios, Master thesis, Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering
Abstract:
This research is part of the ongoing effort of the Seismic Risk Mitigation for Port Systems Grand Challenge. It addresses the problem of numerically simulating the response of sandy soils treated with earthquake drains, for liquefaction risk mitigation. This thesis describes 1)the implementation of finite 1-D elements to simulate the uncoupled mechanical and flow properties of perforated vertical (PV) drains, 2) the investigation of scaling laws for laminar and turbulent flow inside a PV-drain, 3) the validation of the numerical models using a centrifuge experiment (SSK01) performed at UC-Davis (Kamai, et al., 2008). The mechanical and flow behavior of the drains are assumed to be uncoupled. The mechanical behavior is treated as a truss element, taking into account the axial stiffness and assuming zero bending stiffness. The flow behavior is treated using the phenomenological Darcy-Weisbach equation. The elements are implemented in the Opensees framework. Two implementations are presented, one for laminar drains, and one for fully turbulent drains. Both of these implementations are used to estimate also the effect of drain storage capacity. It has been illustrated that the flow in the drains in model scale and in prototype scale might be qualitatively different. If the centrifuge model is scaled N times Reynolds number (Re) is N times larger in prototype scale, so under common situations model scale flow can be laminar even if at the prototype scale flow is fully turbulent. A methodology is presented to elect properties of model scale drains (where flow is laminar) to represent prototype drains (where flow is turbulent). Validation has been performed against SSK01 centrifuge test. Results show good agreement with experimental data. Limitations of the constitutive soil model and the selected input parameters are discussed. Model scale results validate the consideration of the storage capacity effect, and thus use of the implemented drain elements. On the other hand the need for turbulent flow (rather than laminar) drains does not affect significantly the results of the specific test used.
