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...
Biggest Highway Rebuild
The reconstruction of the Wisconsin Interstate 90 and 94 involved 32 miles of 6-lane pavement. Most of the concrete aggregate for the job was recycled concrete pavement and all pavement...
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...
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...
LAX Engineers Beat the Clock
Foreign and domestic crowds flying in for the Olympics were no problem for the Los Angeles Airport (LAX), thanks to the expansion and improvements completed a month earlier. LAX more than...
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....
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....
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 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...
Can Management Techniques Solve Pavement Woes?
Cities are increasingly turning to systematic procedures for allocating scare manpower and funds and measuring pavement repair and rehabilitation needs. Many cities have adopted pavement...
Pavement Recycling: Stopgap or Remedy?
Recycled pavements cost less than new asphalt concrete overlays, but no long term data has ratified how recycled pavements' strength and durability compare to virgin material....
Effects of Fines in Gravel Bed Streams Behavior
A model-gravel bed stream is studied in the laboratory. Flow visualization of bedload motion correlates with bursting phenomena near the bed. The bedload variation as a result of the addition...
