Asphalt Pavements of the Future
There will be major changes in the Hot Mix Asphalt Industry throughout the next decade and into the 21st century. Acquisitions, diversification, SHRP, the emergence of new technologies...
New Concrete and Asphalt Mixes on the Horizon
Significant research is currently 'in progress' which is intended to develop modified or new design methodologies that will result in improved pavement performance....
The Road to Drained Pavements
In California, a fast-draining base course within the pavement structure is now the preferred design. For the first time, the 1987 edition of the California Highway Design Manual recommends...
Concrete Overlays Challenge Asphalt
When a pavement needs more than minor repair but not total replacement, bonded and unbonded concrete overlays and inlays are options to consider. The article describes four projects where...
Paving with RCC
Roller compacted concrete pavement differs from the RCC used for dams. Since 1984, when the first full scale RCC pavement in the U.S. was installed by the Corps of Engineers at Ft. Hood,...
Survey of Airport Pavement Distress in Cold Regions
The most common pavement problems were associated with non-traffic related phenomena and included pre-existing cracks reflecting through asphalt concrete overlay (in two years or less),...
A Thermal Analysis of Pavement Thawing
This research focuses on identifying the spring thawing period for the purpose of timing load restrictions on low to medium volume roads in frost-susceptible areas. Cases evaluated include...
Concrete Block Paving for Marine Terminals
This paper describes the application of concrete block pavements to marine terminals. The Corps of Engineers flexible pavement design approach can be modified to provide a conservative...
Roller Compacted Concrete Pavement for Marine Terminals
This paper describes recent intermodal yard paving projects at the Port of Tacoma, Washington which have utilized a relatively new paving process known as Roller Compacted Concrete (RCC)....
Asphalt Pavement Modifiers
Modifiers or additives to asphalt concrete pavements are being researched or marketed by many major chemical firms. Modifiers or additives are used to stiffen the asphalt in hot weather...
Parking Lot Gets White Top
The many-acre parking lot at the Valley Fair Mall shopping center in Salt Lake City, Utah is described. In 1985 the asphalt pavement was overlaid with concrete, making it one of the relatively...
Construction of Roller-Compacted Concrete Pavement
Roller-compacted concrete pavement (RCCP) is the product of a relatively new concrete paving technology in which a zero-slump portland cement concrete mixture is spread with modified asphalt...
Computer Assisted Pavement
In Rancho Palos Verdes, Calif. a 4,300 ft. long test installation of the Contained Rock Asphalt Mat (CRAM) Pavement System is expected to have a 50 year life. It cost a third less than...
New Runways Take Off
The two mile long runway 9-27, now being constructed at Houston Intercontinental Airport, was built for about 30% ($7 million) less than if designed conventionally. Rather than concrete...
Life Cycle Analysis
Of all the infrastructure elements, pavement performance has probably received more research than any. Similarly, there has been more application of pavement research. The concepts that...
On-Site Containment of PCB-Contaminated Soils
A remedial investigation/design project, with subsequent post-closure monitoring, was conducted for upland areas containing PCBs at an industrial site in New Bedford, Massachusetts. A...
Rigid Pavement Rehabilitation: Interstate 95?Duval County, Florida
Rehabilitation studies have been conducted on Interstate 95 in Duval County, Florida. The rigid, unreinforced pavements were constructed in the late 1950's and 1940's....
Construction of Foz do Areia Dam
The methods and equipment for the construction of Foz do Areia Dam during 1976-1980 in Brazil are described. Special emphasis is given to the rockfill construction. Foz do Areia was the...
Pavement Recycling: Stopgap or Remedy?
Recycled pavements cost less than new asphalt concrete overlays, but no long term data has ratified how recycled pavements' strength and durability compare to virgin material....
Asphalt: Great Expectations
A $50 million, five year research program has been proposed for research into asphalt as part of the larger ($150 million) Strategic Transportation Research Study (STRS). The research...
