Historic Seawalls of the Boston Harbor, Massachusetts Region: Evolution, Construction and Repair
The earliest seawalls in the Boston region were of crib construction. Cobb cribs had an open framework and could readily be floated into position and sunk with rock from local sources....
Draft Chapter 2?Planning and Design Guidelines for Small Craft Harbors?Entrance Design and Breakwaters
The paper will present a very preliminary draft of the second chapter of an ASCE manual that is currently being developed. The new manual is entitled Planning and Design Guidelines for...
System Operating Strategies in Water Rights Modeling and Analysis
The appropriative surface water rights permit structure in Texas has provided the impetus to develop TAMUWRAP, a river basin simulation package that will allow the response of multiple...
Design and Maintenance of Rural Water Supply Systems for Improved Performance
During the period 1980-1990 the United Nations sponsored a comprehensive effort to bring potable water supplies throughout the world. For many urban and rural areas in developing countries...

Building Better Bridges: Concrete Vs. Steel
The authors debate the merits of concrete segmental and steel bridge design and construction based on five criteria: initial and life-cycle costs; structural advantages; durability; construction...
The Diagnosis of Pavement Ills
The paper defines the 'health' of a road pavement in terms of parameters of serviceability, safety and structural integrity and defines 'illness' as any departure from 'healthy' values...
Use of the Break-Off Method for the Evaluation of High Performance Concrete
The Break-Off test is one of the recent developments for testing in-place concrete strength. This research was undertaken to investigate the reliability of the Break-Off test as a measure...
Masonry as a Structural Material
Four case studies are presented which illustrate the use of masonry as a structural material. Results of laboratory studies for unreinforced piers subjected to in-plane lateral forces,...
Application of SMA Technology in Georgia
In 1991, the Georgia Department of Transportation participated in a cooperative effort with the Federal Highway Administration to conduct one of a series of field evaluations of Stone...
A Laboratory Investigation on Long-Term Performance of Asphalt Concrete Treated with Antistripping Additives
Asphalt concrete pavement is susceptible to moisture damage and the damage caused by repeated freeze-thaw cycles is a major problem. This paper summarizes a laboratory investigation for...
Realistic Specifications for Manufactured Sand
Data which demonstrate the beneficial effect of using fine aggregate having high fines contents on concrete properties are presented. All data indicate that the use of a high fines content...
High Strength, Low Permeability Garage Rehab Concrete
Physical and engineering properties of high strength structural lightweight concrete used to replace deteriorated concrete in garage structure rehabilitation programs are reported. Structurally...
Concreting at Subfreezing Temperatures
Temperature affects the rate at which portland cement concrete develops strength. Below about 20?C, strength gain is retarded, whereas at higher temperatures it is accelerated. Strength...
Forensic Analysis Techniques for Joint Sealants
Growing concerns involving the field performance of pavement joint sealant materials has illustrated the need for forensic capabilities in determining the cause of sealant failures. Methods...
Implementation of Material Requirements in Specifications
This paper focuses on where to find information on materials, their compatibility, minimum standards and specifying of materials and their use. The paper also presents case histories on...
A Theoretical Approach to Characterize Reinforced Concrete Using Stress Waves
Although advances in nondestructive evaluation of structural concrete have been made, the ultrasonic determination of the placement of steel reinforcement in concrete remains difficult....
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...
Innovations for NDT of Concrete Structures
The proposed paper presents three recent innovations for sonic and ultrasonic Non-Destructive Testing (NDT) of concrete structures which greatly increase the utility and speed of many...
