Excerpt from The Modern Asphalt Pavement The Subsoil Base - As the foundation of a pavement, of any kind, is placed upon the soil and supported by the latter, it is a matter of vital importance that this latter support should be adequate, and it will only prove adequate if the subsoil is not subject to displacement from settlement or frost and is thoroughly drained. With sandy soils which are well compacted and which, from their nature, are well drained and dry there is no difficulty in the preparation of a satisfactory subgrade. Trenches in such soils, if they occur, can be solidly refilled with the aid of water. If the subgrade is a true sand, as in the neighborhood of seabeaches, it may be necessary, in order to compact the surface, to spread a course of gravel between the sand and the base in order to be able to roll it properly.

Asphalt Renaissance is a brilliant account of the rebirth and re-imagining of the art of street painting by top artist Kurt Wenner. He revolutionized this tradition by creating a technique for drawing on pavement in 3-D. This system enables him to craft astounding images that reach out of the ground toward the viewer and appear perilously deep. Wenner has traveled the world over and his incredible art is both a global and an Internet phenomenon.

This work deals with conventional and new relationships between various viscoelastic properties of road bitumen, determined under different test modes, such as constant stress, constant deformation or cyclic load. Approximate formulas have been derived for prediction of the rheological properties of asphalt based on its standard parameters such as penetration and softening point. The work is intended for researchers and engineers in road paving industry. It may be also of interest for teachers and Civil Engineering students.

This is the first comprehensive history of the world's roads, highways, bridges, and the people and vehicles that traverse them, from prehistoric times to the present. Encyclopedic in its scope, fascinating in its details, Ways of the World is a unique work for reference and browsing. Maxwell Lay considers the myriad aspects of roads and their users: the earliest pathways, the rise of wheeled vehicles and animals to pull them, the development of surfaced roads, the motives for road and bridge building, and the rise of cars and their influence on roads, cities, and society. The work is amply illustrated, well indexed and cross-referenced, and includes a chronology of road history and a full bibliography. It is indispensable for anyone interested in travel, history, geography, transportation, cars, or the history of technology.

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.
