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...

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 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...

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 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...

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...

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....

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,...

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...

Performance of Recycled Asphalt Concrete Materials in an Arid Climate
Recycling of asphalt concrete pavement is a common practice for highway agencies. In 1981, the Arizona Department of Transportation (ADOT) constructed eight test sections in on experimental...

Performance of Free Draining Base Course at Fort Campbell, Kentucky
In 1990 a free draining base course layer was constructed in the structural section of a pavement to be used as a military vehicle maintenance yard at Port Campbell, Kentucky. The Corps...

Physicochemical and Rheological Properties of Microwave Recyled Asphalt Binders
The purpose of this study was to analyze microwave recycled asphalt binders using Gel Permeation Chromatography (GPC), Fourier-Transform Infrared Spectroscopy (FTIR), and Dynamic Mechanical...

Reliability-Based Design for Feeeze-Thaw Concrete
Observation of pavements in Iowa shows results from the test for freezing and thawing of concrete, ASTM C-666, is not always consistent with field performance. Similar concrete made with...

Rehabilitation of Chloride Damaged Concrete
There are several methods of rehabilitating structural concrete that must deal with the presence of chlorides. It is critical that the rehabilitation designer recognize the abilities of...
