Infrastructure Management and Planning for the City of Seattle
This paper summarizes the current planning effort that the City of Seattle's Engineering Department (SED) is undertaking for Transportation Infrastructure Management. The...
Evaluation of Structures by Dynamic Load Testing
The Frequency Sweep Method for the evaluation of structures by dynamic load testing was developed by the senior author. It is a non-destructive testing (NDT) method that was originally...
New Pavement from Old Concrete
Recycling portland cement concrete has gained momentum as an alternative to resurfacing aging highway and airfield pavements. Recycling cuts down rawmaterial requirements, reduces the...
Microcomputers in Highway Drainage Design
This paper discusses some of the benefits and uses of microcomputers in highway drainage design and discusses the programs presently being developed. Subjects covered include hydrologic...
Tensile Fracture and Fatigue of Cement Stabilized Soil
Portland cement stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts....

Basic Considerations for the Planning and Implementation of an Urban Area Traffic Sign and Pavement Marking Microcomputer Based Inventory and Record Keeping System
This paper presents basic concepts and operations which are necessary to put into place a microcomputer based inventory system. The paper briefly examines past experience, discusses microcomputer...
Pavement Management Data Collection and Analysis
Pavement management systems (PMS) quantify the inventories of maintainable elements under an engineer/manager's jurisdiction including roadways, shoulders, bridges, culverts, guardrails,...
Recent Developments, Future Needs and Opportunities in Pavement Technology and Management
The Strategic Highway Research Program (SHRP) represents a massive research effort aimed at developing implementable solutions to five well-defined pavement problem areas. Pavement management...
Developments in New and Existing Materials
Materials engineering has emerged as an identifiable professional practice within civil engineering in the past few years. Although materials engineering is not new, the concept that this...
Rating Pavements by Computer
Pavement rating is a necessary and labor-intensive job and one with a high turnover rate of personnel. Also, rating scores are often inconsistent from day to day, or between different...
What Do Pavements Cost?
Life-cycle costing is a rational tool used to forestall problems with highway infrastructure. Currently this tool is still an imprecise one. The Federal Highway Administration has a system...
Vehicle Design Exchange With Other Disciplines
Vehicle Design as one of the eight designated areas of interest or 'disciplines' includes a wide range of interests within itself. It can range from overall vehicle...
Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...
Karnafuli Hydroelectric Project, Hydraulic Model Studies of Spillway Damage
The Karnafuli Hydroelectric Project is located in Bangladesh. On August 13, 1961, distress was noted in the spillway flow. A special Board of Consultants considered possible causes for...
Rigid Pavement Rehabilitation: Interstate 95—Duval County, Florida
Rehabilitation studies have been conducted on Interstate 95 in Duval County, Florida. The rigid, unreinforced pavements were constructed in the late 1950's and 1940's....
Embankment Overtopping Tests to Evaluate Damage
The paper reports on studies of embankments 6 ft high, 10 to 22 ft in crest width, and 3 ft in length, with slope varying from 2:1 to 4:1. Embankment surfaces include pavement, grass,...
Roller Compacted Concrete Pavements in British Columbia, Canada
Roller Compacted Concrete (RCC) pavement is an outgrowth of the traditional cement-treated aggregate base (soil-cement) method of street and highway construction. The major use in British...
