Mutual Causation in Highway Construction and Economic Development

This paper investigates the relationship between the growth of road networks and regional development. We test for mutual causality between the growth of road networks (which are divided functionally into local roads and highways) and changes in county-level population and employment. We employ a panel data set containing observations of road mileage by type for all Minnesota counties over the ...

Application of Geology to Highway Engineering

In Indiana we have surely developed a “professional con­ sciousness. We have done quite a bit toward enforcement of the registration act. We have an adopted code of ethics. We now have four local chapters in addition to our state chapter and state society. In the last session of the state legislature, we sponsored three bills. With the able guidance of Engineer Clyde Walb and others, two of the...

Highway Embankment Construction Procedure

some heavy clay soils of the A6 and A7 types with tar emul­ sions and cutbacks on an experimental subgrade stabilization during the summer of 1937, we found that this type of soil stabilization presents some very different problems from those of soil-aggregate stabilization. Soil-cement stabilization, as described by Mr. Myers, also presents some interesting problems. According to its claims, t...

Contracting Methods for Highway Construction

Transportation construction is a large industry—particularly highway construction, on which more than $50 billion is spent annually. Small improvements can result in significant savings in time and cost, as well as better quality and fewer disputes. In recent years, many innovations have occurred in highway construction. The atmosphere within the industry is highly charged with optimism, uncert...
