New Pavement Materials
New materials and construction techniques are constantly being evaluated to extend pavement life and to improve overall performance of highway and airfield pavements. To be beneficial,...

Modelling the Effects of Wind on Pavement Runoff
Phase I of this study, the primary focus of this paper, consists of the development of a mathematical model to predict runoff depths from a pavement under uniform wind conditions. The...

Wisconsin Adds Tires to Asphalt Paving Mix

New Roads for the Micro
Using microcomputers loaded with database software and Fortran programming, engineers are gaining control of pavement maintenance. A number of factors, from urban sprawl to constricting...

Comparing Benefits of Safety and Non-Safety Programs
The objective of this presentation is to compare benefit-cost ratios for major highway construction projects to those for highway safety projects, such as: (1) new highways, (2) major...

Highway Safety - Planning for the Future
Because motor vehicle traffic is expected to continue to grow, renewed efforts will be required to prevent the problem of motor vehicle crash deaths and injuries growing much larger than...

Plans and Programming for Highway Safety to the Year 2010
Many factors have contributed to improvement in highway safety including more crashworthy vehicle design, increased usage of occupant restraints, growing public intolerance of DWI, and...

Driving in the Fast Track
Fast track concrete allows traffic back on pavement within 24 hours. Fast track concrete has been developing in Iowa for the last three years. Traffic rerouting, an inconvenience that...

Implementing a State PMS
Arizona State Pavement Management System (PMS) is described in this paper. Experience shows that many factors must be considered in deciding how to maintain a particular mile of the road...

Future Federal Pavement Policy
Pavement design is entering a new era of increased attention and research insight. Since most of our pavements are in place and under traffic, much of future design will be for their rehabilitation...

Concrete Pavement Rehabilitation Research Findings
A study to improve the procedures for evaluating and rehabilitating concrete pavements was undertaken in 1985. Field and analytical studies have facilitated a new knowledge and understanding...

Safety on 21st Century Highways
Consistently high geometric design standards, adequate pavement skid resistance, drainage and markings, and appropriate signing, delineation and lighting all reduce the potential for driver...

Innovative New Developments in Concrete Slipform Paving Equipment for the 21st Century
The Surface Transportation Assistance Act of 1982 gave new life back to the concrete paving industry by bringing a welcomed and necessary increase in the volume of concrete paving work....

Portland Cement Concrete Pavement in the 21st Century
The future of Portland Cement Concrete Paving in the 21st Century holds vast challenges that we as industry must be ready to tackle head on. Looking ahead, we see an even more vital role...

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...
