Fast Monte Carlo Simulations and Safety Index Checking
This paper presents recent techniques which require a small number of simulations to assess the structural reliability. They combine both the concept of importance zones in the random...
Wave Run-Up and Reflection on a Permeable Sea Wall
The swash oscillation on a sloping seawall made of step-shaped concrete blocks, waves and water particle velocity in front of the seawall were measured. It was inferred that incident waves...
The Evolution of Breakwater Design
The purpose of this paper is to present a view of the evolution of both the rubble mound and vertical faced breakwaters from the earliest design through the Iribarren and Hudson era. Determining...
The Future of the Past: Historic Preservation at the Metropolitan Washington Airports
The historic significance and unique architectural character of Washington National and Washington Dulles International Airports have presented the Metropolitan Washington Airports Authority...
Dynamic Loading of Airfield Pavements Caused by Aircraft Operations on Rough Runways
This paper presents results for dynamic pavement loading of various aircraft under takeoff and taxing scenarios. The data were obtained from computer simulation and applied to the Corps...
Implementation of Elastic Layered Theory for Design of Unbonded Overlays
The U.S. Army and Air Force have implemented the elastic layered theory for design of unbonded overlays for rigid airfield pavements. The procedure allows for design of unbonded overlays...
The Use of Crumb Rubber Modifier in Hot-Mix Asphalt
This paper summarizes the literature on the use of CRM as an additive in HMA. Wet and dry processes are discussed and the objective of each explained. Material, design and construction...
Modified Asphalt Binders - How Do They Compare?
This report summarizes some of the research that the US Army Engineer Waterways Experiment Station (WES) has conducted on asphalt modification of airport/airfield pavements. these laboratory...
Utilization of Phosphogypsum-Based Slag Aggregate in Portland Cement and Asphaltic Concrete Mixtures
This study centers around the potential utilization of phosphogypsum-based slag aggregate as a substitute for coarse aggregate in both portland cement and asphaltic concrete surfaces for...
Recycling Portland Cement Concrete Pavement at the Contractor's Option
This paper summarizes three portland cement concrete airfield pavement recycling projects at the Outagamie County Airport in Appleton, Wisconsin. The specifications for the projects did...
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...
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...

Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...

Modular Evolution
The construction industry typically thinks of modular steel bridges in terms of the World War II vintage Bailey Bridge. The Bailey Bridge was designed to be quickly deployed to replace...
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...
Lightweight Concrete for a Segmental Bridge
Structural lightweight concrete can help increase the stiffness and decrease the mass of a bridge; both are qualities that make the structure more likely to survive an earthquake. Ordinarily,...
An Object-Oriented Approach for Reinforced Concrete Design
The use of the object-oriented programming approach in developing applications for the analysis and design of reinforced concrete members is discussed. Two object oriented programming...
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,...
