Predicted Service Life of Armor Stone: A Case History
Laboratory testing for determination of true rock quality in terms of expected performance is not clear-cut, may be misleading, and requires extensive interpretation by an expert. This...
Making the Most of HPC
Developing high-performance concrete (HPC) was only the first step toward bringing a material with improved durability, strength, constructability, and mechanical properties to the bridge...
Megaproject Management
By the dredging and landfill project manager for the Port of Los Angeles and Alan E. Alcorn, P.E., an associate vice president of Moffat and Nichol Engineers in Los Angeles. The Pier 400...
Gap Analysis for Durability of Fiber Reinforced Polymer Composite in Civil Infrastructure
Prepared by the Civil Engineering Research Foundation. This report provides the results of a study on what is known and not known about the use of...
Containing the Cold War's Hot Waste
A new method for the construction, verification, and maintenance of underground vaults isolates and contains radioactive burial sites without excavation or drilling in contaminated areas....
Catching Up on Composites
Until recently, Japan and Germany were way ahead of the U.S. in composite material technology for construction. Lighter, stronger and possibly more durable than conventional materials...
Evaluation of the Troxler Model 4430 Water-Cement Gauge
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes a HITEC evaluation designed to determine...

Fabric Roof Design Responds to New Technologies
A combination of newer synthetic materials and advanced structural design technologies have given contemporary tensioned fabric roofs vastly improved energy performance and far greater...
Sandstone Materials Used as Riprap
A study was conducted to determine if sandstone materials could be potentially used as riprap. Nineteen rock samples (16 sandstone samples) were collected in six western states. The rock...

ASTM C666 (A) Freeze-Thaw Durability of Air-Entrained Wet- and Dry-Mix Shotcrete
In order to assess the freeze-thaw durability of shotcrete, six samples of dry-mix shotcrete and one sample of wet-mix shotcrete were mixed outdoors at Hydro-Quebec's research institute...
Testing of Concrete Permeability for Durability Evaluation
Field and laboratory permeability tests are being performed to evaluate the durability of concrete in Florida. These tests are part of an extensive research program to develop a durability...
Durability and Ductility of Advanced Composites
In recent years, several fiber reinforced composites have been successfully used as prestressing materials for demonstration highway structures. Since these materials are relatively brittle...
Durability of High Performance Concrete
The freeze-thaw durability and the resistance to chloride penetration of high performance concrete (HPC) developed for highway applications were investigated. This paper summarizes the...
Quartzite?A Hard Rock Approach to Rubble Mounds
The quality of stone in rubble mound structures has always been a concern but seems to be more so the past few years. Breakwaters built in the 1920's using granite armour...
The 1984 Major Rehab of the Muskegon Harbor, MI South Breakwater: An Extreme Example of Misguided Design of a Stone Structure
It can be inferred from the Shore Protection Manual that the stability of any coastal structure is increased in proportion to the weights of the armorstones. The south breakwater at Muskegon...
Alkali-Silica Reactivity: An Overview of a Concrete Durabilty Problem
An overview of the problem of alkali-silica reactivity (ASR) is presented. It is a chemical reaction that can occur between aggregates containing certain forms of silica and the alkaline...
Investigation of Concrete at a Middle East Plant
In recent years, reinforced concrete construction in the Middle East has been beset by durability problems. The causes include availability of a limited number of skilled workers, marginal...
