Book excerpt: Load transfer at rigid pavement joints is a complex mechanism that can vary with concrete pavement temperature, age, moisture content, construction quality, magnitude and repetition of load, and type of joint. The FAA design procedure assumes 25 percent of the load applied to an edge of a slab is transferred at the joint to an adjacent unloaded slab. This effectively reduces the edge stress in the loaded slab by 25 percent compared to a free edge condition allowing fbr a reduced slab thickness. If the load transfer assumption is violated through a degradation of the joint system, the pavement life can be significantly reduced. The purpose of this study was to evaluate the load transfer effectiveness of several concrete pavement joint types by using nondestructive testing techniques. Several joint types and conditions that affect the efficiency of the joints were considered. Nondestructive field testing was conducted at four U.S. airports with a heavyweight deflectometer (HWD). Joint load transfer was found to be stochastic and not be adequately described by a single deterministic value. Probability distributions for the joint types and conditions were proposed. Based upon these probability distribution flinctions, the likelihood of observing mean values of load transfer less than 25 percent ranges from 60 to 100 percent, depending on the joint type and conditions.

Book excerpt: The report discusses the evolutionary developments in mechanistic dowel behaviour theory proposed by Bradbury, Grinter, Friberg, Lessels, Timoshenko, and Westergaard. New findings relating to dowel bar behaviour obtained from finite-element modelling are discussed. A sampling of pavement performance model which use empirical or empirical-mechanistic statistical regressions to estimate load transfer performance (expressed as transverse joint faulting) in terms of material, environmental and traffic variables not considered by theoretical analysis is presented. The findings from a limited number of field performance and laboratory studies are summarised.

This book was released on 2003 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to evaluate the impact of the number of dowel bars and dowel location on joint performance and ultimately on pavement performance. For this research, test sections were designed, constructed, and tested in actual field service pavement. Test sections were developed to include areas with load transfer assemblies having three and four dowels in the outer wheel path only, areas with no joint reinforcement whatsoever, and full lane dowel basket assemblies as the control. Two adjacent paving projects provided both rural and urban settings and differing base materials. This report documents the approach to implementing the study and provides discussion and suggestions based on the results of the research.

This book was released on 1995 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 1986 project evaluated bituminous undersealing and different retrofitted load transfer devices in Chase County on U.S. 50. This report follows the progress of the project from 1986 until 1993. The project consisted of two 305 m (1000 ft) test sections and one 305 m (1000 ft) control section. Test section 1 received patching and a 100 mm (4 in.) overlay and no undersealing. Test section 2 was constructed with no overlay, but it had undersealing and also contained load transfer devices. The devices used were: drilled and grouted dowel bars with patching, dowel bars placed on chairs in sawed slots, and a Double V device. The control section was constructed by regular construction techniques. The data show that undersealing gave the pavement added strength. It also helped to control the deflections of the pavement. Load transfer devices distributed forces and helped the patches last longer. The load transfer device that worked best was the Double V device. The bituminous overlay has given effective performance for more than eight years with a smoother ride than the load transfer device section.
