Groundwater Recovery Program for Southern California
Under its new Groundwater Recovery Program (GRP), The Metropolitan Water District of Southern California will improve regional water supply reliability by providing financial assistance...
Analytical Prediction of Gasoline Thickness on the Water Table
With the increased use of immiscible fluid products such as gasoline, the threats to groundwater resources by hydrocarbon products are increasing. The success of recovery of the hydrocarbon...
Applying the ARMOS and MOFAT Models to a Major Oil Spill
A study was undertaken to evaluate the impact of a crude oil pipeline rupture in the recharge area of the aquifer serving most of West Tennessee. The main challenge was to model the volume...

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...
Investigation of a Concrete Blistering Failure
During construction of a concrete pavement at a military airfield, numerous small blisters formed on the concrete surface behind the slipform paver and were filled by the contractor using...
Forensic Analysis of a Two-Component Joint Sealant Using FTIR-ATR
Fourier-Transform Infrared Spectroscopy using Attenuated Total Internal Reflectance (FTIR-ATR) was used to chemically identify joint sealants obtained from an airfield pavement joint which...
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...
The Role of Nondestructive Testing in Assessing the Infrastructure Crisis
At present the role of nondestructive testing in the evaluation of infrastructure deterioration is an extremely limited one. In the Author's experience this is, in part, due to a reluctance...
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...
Principles of Infrared Thermography and Application for Assessment of the Deterioration of the Bridge Deck at the Zoo Interchange
This paper details the principles of infrared thermography from the underlying theoretical considerations to the physical constraints involved with performing the test. Infrared (IR) thermography...
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,...
The SHRP-LTPP Asphalt Resilient Modulus Pilot Study
A SHRP asphalt concrete resilient modulus pilot study was initiated to provide important supplemental information related to the AC Mr program. Initially,...
A More Rational Approach to Pavements
It is the intent of this paper to demonstrate how purely probabilistic arguments can be used to formulate a rational (phenomenonological) model of the particulate media that comprise pavement...
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...
Evaluation of Fine Aggregate Particle Shape and Texture
In an effort to minimize or eliminate permanent deformation (rutting) of heavy duty asphalt pavements most governing agencies now limit the amount of natural sand which generally (not...
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...
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...
Procedures for Evaluating Aggregate Gradation Specifications
The construction and rehabilitation of transportation facilities annually consumes huge quantities of aggregates. And, the variability in supply and demand for these materials as well...
