  • Revised 616.6 Temporary Traffic Control Zone Devices (MUTCD 6F) to add Type IV Fluorescent Orange, replacing Type IV Orange and Type IX/XI Fluorescent Orange for trim-line and drum-like channelizers. Type IV Fluorescent Orange will provide better visibility and luminance at driver's normal observation angle. Type IX/XI are designed for higher observation angle performance and incur higher costs to the TTCD.
  • Revised 1041.7 Polypropylene Culvert Pipe Properties for current AASHTO references concerning polypropylene storm sewer pipe and NTPEP requirement to be placed on the qualified list. 750.7.2 was also updated to clean up some wording to accurately describe which pipe type is allowable for each group of pipe.
  • 1017 Slag Cement was revised to better define slag. Slag cement is the industry terminalolgy and intended material.
  • Modify referenced ASTM materal standards for HDPE in 1060 Electrical Conduit to accurately reflect use as electrical conduit.
  • 1007 Aggregate for Base processes for the Districts and CM Lab are being updated to establish how comparable and non-comparable tests and material will be handled.
  • 242.6 Specifying One Pavement Type was updated to change documentation requirements from Design Exception, to file a memo in eProjects. The State Design Engineer and State Construction and Materials Engineer will still need to be informed when one pavement type is specified on a MoDOT contract.

  • Updated EPG 751.10.4 and 751.50 to clarify allowed conduit size and junction box size in concrete barrier Type D, Type H, bridge abutment wing and slab.
  • Added the reasoning behind the 90 day camber for typical bridge projects in EPG 751.22 and consideration of line sag is necessary to retrieve accurate camber measurements in EPG 1029.2.13.
  • Updated EPG 750.6.3.3 clarifying that geotextile is required with Rock Blanket, and now requiring in all installations of Rock Ditch Liner.
  • Updated EPG 450 to reflect a change in policy to increase minimum lift thicknesses for Superpave and Bituminous Pavement mixes, as per "four times the nominal maximum aggregate size" as recommended by NCHRP study. Additionally, language was added to explain MSCR Graded binders.
April 18, 2023
  • References to LRFD specifications for development lengths and splice lengths have been updated to those of the current version of the AASHTO LRFD Bridge Design Specifications.
