Nighttime Cement Concrete Pavement Replacement Seattle-Tacoma International Airport
Several airfield improvement projects are currently underway at Seattle-Tacoma International Airport (Sea-Tac), many of which are being constructed using cement concrete pavement. Due...

California Airports: Ground Access Vehicle Trips, Emissions and Emission Reduction Strategies
The following paper discusses the volume of trips and emissions associated with ground access vehicles to an d from California airports, and potential ways to reduce these emissions. this...

Rail Service to Airports
Rail service is available at seven North American airports, and service is available by a shuttle bus connection at more than nine other North American airports. Additionally, rail service...

Optimal Supply of Parking at Airports
The design capacity of parking facilities at airports is generally estimated in relation to one or more standard decision variable such as enplaning passengers, number of employees, and...

Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....

Hydraulic Properties of Surface Runoff on Ash-Mixed Concrete Pavement
The disposal of incinerated sludge ash from wastewater treatment plants is becoming an increasingly difficult problem in highly populated cities. The feasibility of reusing sludge ash...

Exploring Management Alternatives with Interactive Simulation
A drought exercise was held to disseminate information about a proposed change in reservoir management. In the drought exercise, an interactive operations model was used to simulate drought...

Simulating Water Supply Systems of the Raritan Basin
A recently developed interactive river-aquifer system model (IRAS) was used to study the Raritan River Basin as part of the effort to revise the New Jersey Statewide Water Supply Master...

A League of Their Own
New baseball stadiums in Cleveland and Arlington, Tex., opening in April 1994, combine the nostalgia of traditional ballparks with state-of-the-art site planning and structural engineering....

Microsurfacing Urban Pavements
A European maintenance technique called microsurfacing can add years to the service life of cracked, ravelled pavements--with minimal interruption to traffic and for less than half the...

Computer Model for Infiltration System Design
This paper describes a personal computer model which was developed to assist in the design and analysis of infiltration systems. The systems included in the model are infiltration basins,...

Uncertain Reasoning in a Pavement Management System
A major objective of a Pavement Management System (PMS) is to assist highway engineers and managers in making consistent and cost effective decisions related to maintenance and rehabilitation...

Global Network Optimization for Pavement Management
In a state-wide pavement management system, the highway network can be divided into a number of road categories based on traffic level and geographical region. Network optimization analysis...

A Computational Algorithm for Analysis of Rectangular Footings Under Partial Contact with Soil
This paper describes a method to determine the distribution of base pressures under a rectangular footing experiencing partial contact of the footing with soil. Assuming the footing to...

A Speed Prediction Model for New Zealand Highways
This paper outlines a limiting speed model using probabilistic techniques to simulate the different types of vehicles and their performance along a two-lane rural highway. The road to...

Analysis of Port Allen Lock in Elastic-Plastic Soil Medium
Incremental finite element analyses using Drucker-Prager plasticity model are applied to study the interaction of Port Allen Lock with its surrounding soil. The analyses not only consider...

Machine Learning in Civil Engineering ? Important Issues and Challenges
In recent years, machine learning techniques have been applied to help overcome the knowledge acquisition bottleneck of knowledge-based systems in civil engineering. This paper identifies...

An Artificial Neural Network Approach to Pavement Maintenance Decision Support System
An important component of any Pavement Maintenance Decision Support System (PMDSS) is the condition survey and rating procedures. Data obtained from these procedures are the primary basis...

Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...

An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
