![]() AASHTO design method - Calculate the equivalent single axle (18 kip) load, ESAL. Mechanistic-Empirical Design Procedures 1. Pavement Design: Equivalent Single Axle Loads. Rehabilitation Methods other than Overlay derived from the mechanistic Austroads pavement design methodology and the AASHTO-2004 approach are compared for Australian conditions, with consideration. Pavement Design Procedures for Rehabilitation of Existing Pavements 1. ![]() Pavement Design Procedures for New Construction or Reconstruction 1. Economic Evaluation of Alternative Pavement Design Strategies In order to simulate ITD and AASHTO 1993 design methods using MEPDG based on the same assumptions : Traffic characterization in terms of ESALs instead of axle load spectra (ALS). The procedures specified in the 1993 Guide(and the previous versions released in 19) were developed from empirical relationships determined during the AASHO Road Test conducted from 1958 to 1961 outside Ottowa, Illinois. An empirical equations are drawn from the AASHO road test to relate observed or measurable. AASHTO Guide for the Design of Pavement Structures(hereinafter the 1993 Guide). Design-Related Project Level Pavement Managementģ. The empirical pavement design methods have many limitations. Flexible Pavement Design Method ( AASHTO 1993 Method). Pavement Design and Management Principles 1. Part III provides alternative methods for pavement rehabilitation with or without the addition of an overlay, and Part IV provides a framework for future developments using mechanistic design procedures. AASHTO Guide For Design of Pavement Structures 1993 (Referenced as AASHTO below, may be purchased on-line.) NDOT uses and recommends the AASHTO design method. ![]() ![]() Part II offers a detailed method for the design of new pavements or for reconstruction of existing pavements on the existing alignment with new or recycled materials. Part I includes background material to assist the user in the proper interpretation of the design procedures and to provide an understanding of the concepts used in the development of the Guide. The AASHTO method for rigid pavement design was used to calculate the thickness of the Portland cement concrete pavement. Material on overlay design methodology and rehabilitation, including seven overlay procedures and associated options is included. This book provides approaches to pavement design including design and management principals, procedures for new construction or reconstruction, and procedures for rehabilitation of existing pavements. ![]()
