Breaking Load for Rigid Pavement

Transportation Engineering Journal of ASCE, 1970
A method of analysis has been suggested for the calculation of a breaking load for a rigid pavement taking the effect of centrally placed load and temperature independently and assuming a transverse yield line under the load to denote failure. The breaking load results predicted by the proposed method have been compared with those obtained from other ...

Comparative Analyses of Rigid Pavements

Journal of Transportation Engineering, 1983
Stress conditions in concrete pavements were analyzed using the finite element method for slabs on liquid and elastic subgrades. The study consisted of the following parts: (1) The effect of the efficiency of load transfer across the joints; (2) the loading positions that produce the most critical stress and deflection conditions in the pavement; (3 ...

MECHANISTIC DESIGN OF RIGID PAVEMENTS

Proceedings of the International Conference on Concrete Pavements
This paper deals with the development and verification of a stress analysis model (RIGMUL) and the use of this model in a program for the design of rigid pavements. RIGMUL is the result of coupling finite element plate theory with multilayer elastic layer theory and consists of a two-layer rigid slab resting on a semi-infinite three-layer elastic solid

Sensor Installation in Rigid Pavement

Experimental Techniques, 1999
This unique approach for installing strain gages in PCC pavement sections in the Ohio SHRP Test Road was very successful. All sensors were installed during construction with no delays to the contractor, and all gages performed well in controlled vehicle tests which followed.

Soil-cement as a rigid pavement material. [PDF]

Many design methods for soil-cement pavements have been developed and used by road authorities. Without exception, they are empirical and take no account of the stresses which cause failure, or the resistance of soil-cement to these stresses. While most of these pavements have been satisfactory, some have failed in service.

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.

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 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 ...

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.

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
