Temperature Effects on Rigid Pavements

Journal of Transportation Engineering, 1994
An analysis technique, to be used in conjunction with packaged finite‐element programs, is developed for the study of rigid pavements subjected to temperature loading. For illustrative purpose, the pavement is idealized as a thin isotropic plate resting on a Winkler‐type elastic foundation.

Advanced Analysis of Rigid Pavements

Transportation Engineering Journal of ASCE, 1972
STRESSES IN RIGID PAVEMENTS WERE OBTAINED BY USING A FOUNDATION MODEL RATHER THAN THE DENSE LIQUID MODEL. THE FOUNDATION WAS TREATED AS AN ELASTIC CONTINUOUS, BUT DIFFERENT BOUNDARY CONDITIONS WERE CONSIDERED FOR THE PAVEMENT SLAB, AND AN IMPROVED COMPUTATION TECHNIQUE WAS USED.

Rigid Pavement Maintenance for Airfields

Journal of the Aero-Space Transport Division, 1967
The advent of jet aircraft has necessitated a reevaluation of pavement maintenance with respect to smoothness and reducing the probability of foreign object (debris) damage to jet engines and tires. The repair of spalled joints is one facet of rigid pavement maintenance for which repair techniques and materials have been developed and successfully used.

Rigid and Stiff Airport Pavement

Journal of the Aero-Space Transport Division, 1964
A logical testing and design approach for rigid airport paving is reported. A reasonable formulation, design, and testing procedure is developed for stiff airport paving or stiff subbase. Four novel design features are presented: (1) The highly elusive Westergaard’s subgrade modulus is converted to a fixed elastic modulus; (2) stiff materials, such as ...

Concrete Fundamentals for Rigid Pavements

2017
Portland cement concrete (PCC) is the most commonly used construction material in the world. Approximately half of all PCC used in the United States is consumed in the construction of PCC pavements. The constituents of PCC include coarse aggregates, fine aggregate, Portland cement, water, and mineral or chemical admixtures.

Stresses in Jointed Rigid Pavements

Journal of Transportation Engineering, 1999
A novel application of the principles of fracture mechanics combined with multilayered elastic theory is used to obtain the design stresses midway between the transverse joints at the bottom of the longitudinal edge of rigid pavements and for corner loading of slabs without dowels.

Feasibility of reclaimed asphalt pavement in rigid pavement construction

2016
Construction and demolition waste along with waste obtained from reconstruction or resurfacing of pavements produces enormous amount of aggregates. Many studies have been carried out to analyse the use of Recycled Concrete Aggregates (RCA) and Reclaimed Asphalt Pavement (RAP) in flexible and rigid pavement respectively, but very few on each other Due ...

Dynamic analysis of rigid pavement with vehicle–pavement interaction

International Journal of Pavement Engineering, 2009
Study of the dynamic response of pavements due to moving loads such as vehicles and aircraft has received significant attention in recent years because of its relevance to the design of pavements and airport runways. This paper presents an improved solution algorithm based on the finite-element method to analyse rigid pavements under moving vehicular ...

Feasibility of Pavement Temperature as a Surrogate for Performance of Rigid Pavements

Proceedings of the International Conference on Concrete Pavements
As time marches forward communities across the State of Minnesota are experiencing on average higher temperatures, and higher frequency of extreme storms with intense flooding from climate change. For example, from 1951 to 2012 the average temperature and annual precipitation in the Twin Cities has increased by 3.25°F and 5.5 inches, respectively. Over

RIGID PAVEMENT DESIGN FOR AIRFIELDS

Proceedings of the International Conference on Concrete Pavements
This article provides a detailed review of the evolution of rigid pavement design for airfields, particularly under the purview of the U.S. Army Engineer Waterways Experiment Station in Vicksburg, Mississippi. Beginning with an urgent need for airfield pavements around the entry of the United States into World War II, the article tracks the development
