The paper describes the overlay design procedure and the calibration of the models for reflection cracking and permanent deformation through heavy vehicle simulator (HVS) tests. (1) extensive pumping and joint faulting, and eventually, excessive roughness occurs due to inadequate load transfer at joints (no dowel bars).(2) Erosion of the treated base course along the shoulder also occurs, creating a funnel for the infiltration of water.(3) transverse and corner cracking occurs due to insufficient slab thickness in the truck lane.CalME, a Mechanistic–Empirical Program to Analyze and Design Flexible Pavement RehabilitationĪ computer program known as CalME has been developed for analysis and design of new flexible pavements and rehabilitation of existing pavements. Over time and under heavy traffic conditions: It is the basis of the AASHTO Design Guide.This photo shows a typical JPCP pavement designed according to the 1972-1986 versions of the design guide. All other loops became part of the traffic lanes of Interstate 80 near Ottawa, Illinois (100 miles West of Chicago).ĪRT is the largest full-scale pavement test site ever constructed and conducted. It was left in place after the end of the Test in 1960. The AASHTO Design Guide was first issued in 1961.It has been revised and expanded many times.The latest version is the 1993 Guide that includes the overlay design procedure.However the procedure for rigid pavement design is identical in both the 19 guides.Indeed the 1986 guide is the latest and most commonly used guide for rigid pavement design.įor consistency and to avoid confusion, note that when I refer to the 1986 AASHTO procedure, we are talking about the rigid pavement design used in both the 19 design guides.ART- the AASHTO Road Test - was conducted over 2 years between 19.

Why is a new design procedure and accompanying design software tool needed? The spreadsheet contains separate sheets that you can use to determine:- accumulated traffic loadings,- seasonally adjusted k values,- adjusted k-value for depth to rigid layer,and to perform corner break and faulting checks. It is a design tool that will walk you through the design and analysis procedures of the 1998 Supplement to the AASHTO guide. So lets start with a brief overview of what the rigid pavement design software is.The heart of the software is a Microsoft Excel spreadsheet.

I am here to: - give you some background on it,- show you some of the useful features of the software,- show you how to use it,- and point out some of the benefits you will derive by using it. To help highway managers and engineers implement the improved AASHTO 1998 Supplement Design Guide for Rigid Pavements, LTPP developed a software program called Rigid Pavement Design Software. TYPICAL JPCP PAVEMENT (designed according to 1972-1989 versions AASHTO design guides)
