Rigid Pavement Analysis and Design

Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

Primary Topic: Rigid Pavement

Description: This study was conducted to characterize and compare currently available rigid pavement analysis models and design methods and to develop new rigid pavement designs to be evaluated in full-scale experimental projects in an actual highway environment. The analysis models considered include: ILLI-SLAB, JSLAB, WESLIQID, WESLAYER, JCS-1, H51, CRCP-2, and RISC. The design methods include: 1985 AASHTO Guide, Zero-Maintenance JCP-1, California DOT, PCA, RPS-3 Texas SDHPT, ARBP-CRSI and Illinois DOT. The capabilities, limitations, and assumptions of each of these models and methods are discussed in detail to assess their adequacy to assist in the design and analysis of rigid pavements. Based upon the results obtained, several models and methods are recommended for use in the development of new rigid pavement designs. A set of rigid pavement designs, featuring trapezoidal cross sections, widened truck lanes, permeable drainage layer, longitudinal drainage pipe, precoated dowels, shorter joint spacing (for JRCP) and tied PCC shoulders was developed for field testing through experimental projects in the various climatic zones of the United States. A project description form (PDF) is provided for the interested State agencies. Guidelines were developed for .joint load transfer design and joint spacing. Predictive models for doweled and nondoweled joints were developed.
