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...
Standard Methodologies for the Forensic Investigation of Pavements
The high costs of new construction have made the preservation and restoration of existing pavements an attractive alternative to replacement structures. Existing pavements that are to...
An Airfield Pavement Forensic Analysis: Cairo East Air Base
The US Army Engineer Waterways Experiment Station (WES) was requested by the Middle East/Africa Projects Office in April 1989 to provide technical assistance in analyzing an unstable asphalt...
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,...
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,...
Pavement Surface Maintenance: Overview of SHRP H-106 Experimental Installations
The Strategic Highway Research Program (SHRP) is currently conducting an experiment under SHRP project H-106 to evaluate the performance of various materials and procedures used in making...
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...
Successful High Traffic Chip Seal Construction
Chip seal coats are used to extend pavement service life by reducing water and air infiltration and improving skid resistance. Application of chip seals is usually limited to low-traffic...
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...
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...
Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....
Realistic Specifications for Steel Bridge Painting
Specifications play a vital role in a steel bridge painting contract. They not only can ease problems with painting construction, but can also provide a common standard for all parties...
Proper and Improper Use of Specifications
The contractors have an obligation to the clients to provide a product that meets their requirements. In order to accomplish this, these requirements must be properly translated into the...
Improper Uses of Construction Specifications
Uses and abuses of construction specifications is a phenomenon discussed everywhere construction people gather. Issues addressed tend to be both general in nature, and project specific....
Performance of Epoxy-Coated Steel in Continuously Reinforced Concrete Pavement
Two sections of interstate highway in central Oklahoma were recently reconstructed. On both projects, northbound lanes were reinforced with epoxy-coated steel and southbound lanes were...
Design and Construction of a Bonded Fiber Concrete Overlay of CRCP (Louisiana, Interstate Route 10, August 1990)
The purpose of this study was the design and construction of a bonded steel fiber reinforced concrete overlay on an existing 8-inch CRC pavement on Interstate 10 south of Baton Rouge,...
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...
Properties of Composites Using Recycled Plastics
Recycled poly(ethylene terephthalate), PET, mainly recovered from used plastic beverage bottles, can be used to produce unsaturated polyester resins. Polymer concrete (PC) and polymer...
