Book Description
This photo essay details the construction of the original Interstate Highway System in Vermont’s picturesque and largely rural mountainous region through the late 1950s to late ‘70s. During this short time, contractor driven construction equipment innovation was remarkable: 2 1/2 cubic yard shovels were replaced with 4-8 yard shovels and then by massive wheel loaders up to 17 cubic yards; 15-22 ton rock trucks were upped to 50 tons; rudimentary spreading methods with dump trucks using tailgate chains were replaced with CMI Autogrades; and many contractors devised and built ingenious contraptions to increase production. The work attracted many large established road building firms from other States—Lane, Perini, Palazzi, L. G. Defelice, Green Construction from Des Moines, Iowa, as well as Cartier Construction, a division of McNamara from Montreal—seen here clearing and grubbing, pioneering, rock drilling, mucking peat bogs, and excavation sequences including trucks and shovels, loaders, pan scrapers, and a wheel excavator. The manufacturers of construction equipment constitute a virtual directory of the period; Caterpillar, Euclid, Allis-Chalmers, International, Dart, P&H, Bucyrus-Erie, Northwest, Lorain, Lima, Gradall, Barber-Greene, Blaw Knox, CMI, and more.

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.
