Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
Paving Our Ways covers the international history of road paving in an interesting, readable and technically accurate way. It provides an overview of the associated technologies in a historical context. It examines the earliest pavements in Egypt and Mesopotamia and then moves to North Africa, Crete, Greece and Italy, before a review of pavements used by the Romans in their magnificent road system. After its empire collapsed, Roman pavements fell into ruin. The slow recovery of pavements in Europe began in France and then in England. The work of Trésaguet, Telford and McAdam is examined. Asphalt and concrete slowly improved as paving materials in the second part of the 19th century. Major advances occurred in the 20th century with the availability of powerful machinery, pneumatic tyres and bitumen. The advances needed to bring pavements to their current development are explored, as are the tools for financing, constructing, managing and maintaining pavements. The book should appeal to those interested in road paving, and in the history of engineering and transport. It can also serve as a text for courses in engineering history.

Book Description
A book about 25 global women leaders would be remarkable by itself. The fact that it is written by a teenage girl makes it incredible. There is only one word to describe this book - inspiring! - Sunil Gupta, Edward W. Carter Professor of Business, Harvard Business School Just when you thought you knew everything about some of the women shaping our world, you read Maya Sharma's book and realize you didn't know much at all. Smart questions that prompt lively, inspiring, and in-depth answers from incredible women will make your mind wander. A recommended read to all-no matter your age or gender. - Joanna Stern, Senior Personal Tech Columnist, The Wall Street Journal This book is a piece of art. It would have been an impressive book if just two or three of Maya's Wonder Women agreed to do the personal interviews - but she got twenty-five! I plan on gifting this important book to my five granddaughters (and two grandsons) so that they can also grow up to be, like Maya, our next generation of architects for a better, more equal world. - Mitch Lewis, Adventurer and Author, Climbing Your Personal Everest Paving: Conversations with Incredible Women Who are Shaping our World is a provocative and stirring piece of brilliant writing from the up-and-coming Maya Sharma. Impressively, as she is still a student in high school, Maya has expertly featured many inspirational and powerful women from all walks of life and has interviewed them to gain their insights and wisdom on the world today. From their first-hand experiences, Maya's expressive conversations have delved into the difficulties that many women face in the modern world and deftly drawn valuable knowledge from the panoramic fount of the remarkable minds of these global influencers. From how they rose up the ranks to where they sit today, and the challenges they faced on their journey there, to how they stood against them, there is much inspiration and encouragement for the many ambitious women they have paved the way for. In fact, Paving is a force of its own, an audacious undertaking, and an eloquent book of thought-provoking answers and extraordinary stories. There is one pivotal theme: No matter what your circumstances, and whatever adversity you face, with perseverance, achieving your goal is always possible.

Book Description
Asphalt Nation is a major work of urban studies that examines how the automobile has ravaged America’s cities and landscape, and how we can fight back. The automobile was once seen as a boon to American life, eradicating the pollution caused by horses and granting citizens new levels of personal freedom and mobility. But it was not long before the servant became the master—public spaces were designed to accommodate the automobile at the expense of the pedestrian, mass transportation was neglected, and the poor, unable to afford cars, saw their access to jobs and amenities worsen. Now even drivers themselves suffer, as cars choke the highways and pollution and congestion have replaced the fresh air of the open road. Today our world revolves around the car—as a nation, we spend eight billion hours a year stuck in traffic. In Asphalt Nation, Jane Holtz Kay effectively calls for a revolution to reverse our automobile-dependency. Citing successful efforts in places from Portland, Maine, to Portland, Oregon, Kay shows us that radical change is not impossible by any means. She demonstrates that there are economic, political, architectural, and personal solutions that can steer us out of the mess. Asphalt Nation is essential reading for everyone interested in the history of our relationship with the car, and in the prospect of returning to a world of human mobility.

Author: Michael Smith Publisher: Cambridge University Press ISBN: 1009249037 Category : Social Science Languages : en Pages : 337
Book Description
In this book, Michael Smith offers a comparative and interdisciplinary examination of ancient settlements and cities. Early cities varied considerably in their political and economic organization and dynamics. Smith here introduces a coherent approach to urbanism that is transdisciplinary in scope, scientific in epistemology, and anchored in the urban literature of the social sciences. His new insight is 'energized crowding,' a concept that captures the consequences of social interactions within the built environment resulting from increases in population size and density within settlements. Smith explores the implications of features such as empires, states, markets, households, and neighborhoods for urban life and society through case studies from around the world. Direct influences on urban life – as mediated by energized crowding-are organized into institutional (top-down forces) and generative (bottom-up processes). Smith's volume analyzes their similarities and differences with contemporary cities, and highlights the relevance of ancient cities for understanding urbanism and its challenges today.
