Pavement Rehabilitation: Identifying the Need
A procedure for identifying the need for rehabilitation of city and county streets is presented. Key factors requiring consideration include user related factors, maintenance needs, and...

In-Situ Volume-Change Properties by Electro-Osmosis - Theory
The basic concept involves incorporation of a simple electrode system in a field probe, measurement of pore-water pressure changes at the electrodes as a function of time in response to...

Profile Soil Moisture from Surface Measurements
A method is presented for predicting the volumetric soil moisture of the soil profile from the surface layer soil moisture measurement and information on the soil properties of the profile...

Air Retained in Pool by Plunging Water Jet
The volume of air retained in a receiving pool by plunging water jets of different characteristics was measured using an air concentration probe. The effect of jet diameter, height of...

Expansive Soils
Fifty-two papers presented at the Fourth International Conference on Expansive Soils are included; conference panel and open discussions are summarized. Engineers often predict anticipated...

Risk and Liability: The Owner's View

Contractual Arrangements for Construction

Neighborhood Traffic Controls
The issues associated with traffic control in residential neighborhoods are examined. Reasons for the increase in activity in implementing neighborhood traffic control measures are presented....

Energy Conservation and Traffic Control at Low Volume Intersections

Model of Airport Employee Access Traffic
Previous research on airport access has not focused adequate attention on airport employee traffic considering that airports employ nearly one person per daily enplaned passenger. This...

Planning Safe and Efficient Bicycle Crossings
An exclusive bicycle path is considered by many to be the highest type design for bicycle facilities. The most serious problem associated with them is that they cannot be completely separated...

Environmental Impacts of BART and People's Responses
Results are intended for use in Federal transit policy making, in improvement of transit system design, and in simplification of the transit planning process. The study identified specific...

A Practical Method of Second Order Analysis

Threshold of Dilation under Cyclic Loading
The lower threshold of cyclic stress or strain that can be sustained in a soil without a tendency for permanent volume change is an important criterion in many foundation problems. However,...

Self-Regulating Constant Discharge Irrigation Valve
Efficient application of irrigation water depends upon many variables, including precise control of the rate and volume of application. Although devices are available for volumetrically...

Airport Access Volumes From Airline Schedules
A methodology is described for estimating air passenger and visitor automobile traffic volumes at an airport as a function of an airline flight time. The methodology allows for the estimation...

Tehran International Airport
The Tehran International Airport is designed to cope with the following factors: Ability to handle a large volume of traffic at its inception in the early 1980's and increasing...

Simultaneous Equation Model of Travel Demand
A simultaneous equation travel demand model, derived from a choice-theoretic foundation, is conceptually simple, compact, and comprehensive. The advantages over traditional models are:...
