Runway Rehab: A Case for CADD
Hired to design and monitor construction at Boston's Logan Airport, engineers at S E A Consultant's quickly realized that they would have to supplement their...
Monitoring the Impacts of a Coastal Protection Structure on La Guira Bay, Tobago
In the mid 1980s the Trinidad and Tobago Government embarked on a tourism development thrust centered around the island of Tobago. A key feature of this thrust involved extending the Crown...
Driver Response to Fog Conditions ? An Intelligent Approach
The Roads and Traffic Authority (RTA) on NSW is currently examining options for replacing its Driver Aid System on the F6 Tollway south of Sydney. On this road drivers are affected by...
Simulation of the Dynamic Traffic Flow on Urban Road Network
Methods of performing dynamic traffic assignment are needed to simulate traffic conditions on urban highways during peak periods of congestion. In this paper, the route choice behavior...
Manning's n From Experiments with Rainfall-Runoff on Portland Cement Concrete Surfaces
Experiments were conducted under artificial rainfall on Portland cement concrete (PCC) surfaces with variable mean texture depths (MTD) and slopes (S). Rain rates were varied up to 3 in/hr...
Simulation of Subsurface Drainage of Highway Pavements
An analysis of the drainage of a pavement system from initial saturation incorporates a realistic assessment of the drainable porosity of the base. This analysis indicates that if a granular...
Analysis of Pavement-Pipeline Systems After Cut Restoration
The placement of utility pipes normally necessitates many cuts and fills of the existing pavements. Integrity of pipeline and compatible performance of cut restoration and original pavement...
