New Runways Take Off
The two mile long runway 9-27, now being constructed at Houston Intercontinental Airport, was built for about 30% ($7 million) less than if designed conventionally. Rather than concrete...
Spreadsheets: A New Design Tool
New techniques are developing which make computer programming easier. One new technique is spreadsheet programming for microcomputers. Two programs are presented which give a quick overall...
Application and Performance of Structural Materials and Exterior Facades
The papers in this book present some of the current thinking associated with today's construction materials as well as the results of research which is directed toward the...
Experimental Assessment of Performance of Bridges
Among the papers in this book, five assessed the global bridge behavior and the three concentrated on bridge decks. The bridges assessed include prestressed steel plate girder and truss...
Use of Private Contracting in Highway Maintenance
Managing the business of highway and bridge maintenance in this country is largely a function of the public sector. As in the private sector, economic realities during the past decade...
