Computer Assisted Mistakes
The proliferation of computer usage by design engineers will continue to generate change in practice. It will affect the process and production of design. It will affect the relationships...
New Horizons in Construction Materials
While civil engineers have, for centuries, built structures and other physical facilities using whatever materials are available to them, there is always the need for stronger, more durable,...
Load and Resistance Factor Design for Engineered Wood Construction
A Pre-Standard Report
The information contained in this pre-standard report is intended to provide guidance to writers of a load and resistance factor design (LRFD) specification for engineered wood construction....
Basis for Design of Wet Detention Basin BMP's
Two different approaches have typically been used to formulate design criteria for wet detention basin best management practices (BMP's). One approach relies upon solids settling...
Monitoring and Design of Stormwater Control Basins
The City of Austin, Texas, has played a pioneering role in the control of urban nonpoint source pollution by enacting watershed and stormwater ordinances, overseeing detailed monitoring...
Source Control of Oil and Grease in an Urban Area
We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of...
Source Tracing of Toxicants in Storm Drains
Sources of toxic chemicals in storm drains are often difficult to locate and even more difficult to control. Receiving environment chemistry, storm drainage maps, land use information,...
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
Future Federal Pavement Policy
Pavement design is entering a new era of increased attention and research insight. Since most of our pavements are in place and under traffic, much of future design will be for their rehabilitation...
What Will Happen to Local Rural Roads and Bridges
Much of the local rural road and bridge system was not designed for the heavy trucks and farm equipment that are currently using the system. The system will continue to deteriorate unless...
An Essential Municipal Tool?The Residential Street Guide
This paper presents the residential street design guide. The purpose in presenting residential street design considerations is to call attention to a broad range of factors which should...
Safety on 21st Century Highways
Consistently high geometric design standards, adequate pavement skid resistance, drainage and markings, and appropriate signing, delineation and lighting all reduce the potential for driver...
Program on Advanced Technology for the Highway (PATH)
This paper describes a program of research, development and demonstration of advanced technologies for the automobile/highway system created in California, under the general direction...
Roadside Safety Design for the Micro-Mini Vehicles
This paper summarizes the results of a study to evaluate the impact performance of widely used roadside safety elements for a 1,500 lb vehicle and to identify potential modifications that...
Safety Performance Evaluation of 21st Century Appurtenances
A great deal has occurred in the highway safety field in the last 15 years: there have been societal changes which have altered the character of the vehicle fleet; there have been technological...
Portland Cement Concrete Pavement in the 21st Century
The future of Portland Cement Concrete Paving in the 21st Century holds vast challenges that we as industry must be ready to tackle head on. Looking ahead, we see an even more vital role...
Future Driver and Vehicle Characteristics and Their Influence on Highway Design for Safety
Both driver and vehicle characteristics are changing, and these characteristics will continue to change into the 21st century. The purpose of this paper is to identify the major changes...
Safety and Operations Related to Geometrics for 21st Century Highways
Highways designed for the next century must reflect the knowledge gained from research on safety and operations conducted over the last 20 years. Assuming that recent trends toward emphasis...
National Workshop on Highway Research: A Summary
This paper is a summary of national workshop on highway research. Traffic is expected to increase in the future, worsening an already critical urban congestion problem. What are needed...
Traffic and Safety Research Payoffs
