Modelling Climatic Effects on Clay Beneath Slabs

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...

Railroad Electrification in the Pacific Area

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...

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...

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...

Contractual Arrangements for Construction

Risk and Liability: The Owner's View

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....

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...

Energy Conservation and Traffic Control at Low Volume Intersections

A Practical Method of Second Order Analysis

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...

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:...

Multipath Assignment Calibration for the Twin Cities
Several probabilistic multipath traffic assignments were made to the 1970 Twin Cities highway network. Several aggregate measures were selected to determine the goodness of fit to recorded...

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...

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,...

Factors Affecting Reliability of Urban Bus Services
Attitudinal surveys have indicated that travel time reliability is an important attribute of urban transportation services affecting choice of mode of travel. Yet there is no generally...

Volume Changes in Models of Jointed Rock
A number of authors have pointed to the significance of volume increase or dilation in failing rock masses. Although several experimental studies of the compressive and shear strength...
