Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...
Load-Permit Truck Operations in New York State
This paper presents the results of a survey of indivisible-load permit vehicle operations in New York State. The survey was conducted in the context of an investigation into the impacts...
Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...
Surface Treatments for Concrete
The US Army Corps of Engineers initiated in 1984 a research program designated Repair, Evaluation, Maintenance, and Rehabilitation (REMR), one of the work units being the evaluation of...
Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...
Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...
Lessons Learned in Laboratory and Field Evaluation of Accelerated Strength Tests for Quality Control of Concrete Pavements
This paper describes the results of an accelerated strength testing program performed to evaluate flexural strength potential at 28- and 90-days. Based upon a literature review of previous...
Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...
Ports '89
This is a collection of the technical papers presented at the triennial Ports '89 Conference held in Boston, Massachusetts in May 1989. Authors, although predominantly from...
Asphalt-Rubber Concrete?A New Horizon
The performance of asphalt concrete pavements is dependent to a large degree upon the rheological properties of the asphalt binder. Asphalt-rubber as a binder material extends the temperature...
Hot Mix Asphalt Utilization in Railway Trackbeds
Described herein are the rationales for, descriptions of and evaluations of hot-mix asphalt (HMA) trackbed rehabilitation and construction techniques recently utilized in various classes...
Post-Tensioned Transportation
Post-tensioned highways are relatively new. U.S. 220 near Altoona, Pa. has the first major installation in the country. There two miles of pavement are continuous concrete panels, each...
Resilient Moduli of Soils
Laboratory Conditions
Historically, structural pavement design has been based on static testing techniques, such as the CBR. More recently, the profession has placed increased emphasis on repeated load testing...
Highway Project Constructability
Results from on-going research into highway project constructibility are discussed. Research objectives and methods are outlined. Prime constructibility objectives are presented along...
Specification as a Requirement for Hot Mix Asphalt
A brief description of the current national research programs that affect the development of specifications is included in this paper. Elements of the Strategic Highway Research Program...
Roller Compacted Concrete II
This volume includes the papers presented at the 1988 ASCE Specialty Conference on Roller Compacted Concrete. Included in the proceedings are experiences of roller compacted concrete dam...
Compaction Parameters of Roller Compacted Concrete
Density in roller compacted concrete is usually achieved through vibratory compaction. Factors of major influence in attaining densification of a structure with a vibrating roller are...
RCC Pavements in Tasmania, Australia
Over 60,000 m**2 of high strength Roller Compacted Concrete (RCC) pavement has been completed in Tasmania, Australia, since December 1986. Projects have ranged from footpaths and small...
Proportioning RCC Pavement Mixtures
The U. S. Army Corps of Engineers has begun using roller compacted concrete for construction of heavy-duty pavements and low volume streets and roads which are exposed to low-speed tracked...
RCC Storage Pads at Tooele Army Depot, Utah
Two 30. 5 m (100 foot) by 91. 4 m (300 foot) ammunition storage pads, each 381 mm (15 inches) thick, were constructed by the Sacramento District of the U. S. Army Corps of Engineers in...
