All versions of the AASHTO Design Guide are empirical design methods based on field performance data measured at the AASHO Road Test in 1958-60.. The design procedures for reconstruction are similar, except that characterization of recycled materials may be required.

3 – 11 0 Hometown, NJ Description: This project will consist of the construction of a new flexible pavement to extend Route 123 to intersect with Route I-80 in North Jersey.. 2)log10 ( W18 ) = ZR S0 + 9 36 log10 ( SN + 1 ) - 0 20+log10ΔPSI+ 2 32 log10 ( MR ) - 8.. 1 IntroductionThe AASHTO Guide for Design of Pavement Structures (AASHTO, 1993) is the primary document used to design new and rehabilitated highway pavements.. These procedures are summarized below in Sections C 2 and C 3, respectively For simplicity, only the design procedures for new construction are summarized here.. The structural design procedures for swelling and frost heave are the same for both flexible and rigid pavements; these are detailed in Appendix G of the 1993 AASHTO Guide.. General Information Chapter 3 of this manual describes the evolution of the various versions of the AASHTO Design Guide.. 8):(C 1)ΔPSI = ΔPSITR + ΔPSISW + ΔPSIFHin which ΔPSITR, ΔPSISW and ΔPSIFH are the components of serviceability loss attributable to traffic, swelling, and frost heave, respectively.. See the 1993 AASHTO Guide for details of additional procedures (e g , determination of remaining structural life for overlay design) relevant to rehabilitation design.. Approximately 80% of all states use the AASHTO pavement design procedures, with the majority using the 1993 version.. MDT Surfacing Design Guide Chapter 6 New and Reconstructed Pavements January 2015 60 The “standard” pavement design method described in the 1993 AASHTO Guide for the Design of Pavement Structures (1993 Guide) tends to be overly conservative when designing low- volume pavements, especially on poor subgrade soils. 518b7cbc7d
