2013 – Concrete Pavement Specification Changes

Seven Major Specifications were revised or created

  • 499 Concrete - General

    • Prescription mixes Class F, C, S, HP, MS, FS are gone

    • Well graded aggregate requirements for both 451/452 and 511.

  • 451/452 Concrete Pavement

    • Revisions to adopt SS 888 ODOT QC/QA pavement concrete specifications

    • 455 Quality Control Plan, Testing QC/QA Concrete

      • Incorporates concrete quality control specifications for 511 and 451/452 into one document

  • Supplements 1126/1127

    • S1126 Mix design submittal for JMF

    • S1127 New Pay factor criteria for 451, 452 and 511

      Three other pavement specifications were updated to reflect material changes

    • 255 Full Depth Removal with Rigid Replacement

      • RRCM - special mix design for rapid repair concrete was added.

    • 608 Walks, Curb Ramps, and Steps

    • 609 Curbing, Concrete Medians, and Traffic Islands


451 452 specification changes

451-452 Specification Changes

  • Materials section was updated to reflect the modifications to 499.

    • References to 455 Quality Control Plan, Testing QC/QA Concrete

  • Basis of Payment was modified to include “with QC/QA” or without.

  • Longitudinal tining is now default. Transverse tining only allowed in small areas approved by Engineer.

  • MIT Scan-2 Equipment is required for

    DBI paving.

  • 451.18/S1127 Strength Pay Factors


2013 with qc qa or without

2013 – “with QC/QA” or without?

Without QC/QA

  • Contractor performs QC to meet CMS 499.

  • ODOT Perform QC checks on project for compliance with CMS 499 (slump, air, yield).

  • Beam for every 7500yd2 or fraction thereof daily by ODOT.

  • Supplier/Contractor responsible to assure your well graded aggregates are maintained in Zone II.

  • Core for every 2000yd2 by contractor per S1064.

    With QC/QA

  • CMS 455 governs QC/QA in addition to CMS 499


  • 455 quality control requirements

    455 Quality Control Requirements

    • Incorporates concrete quality control specifications from SS 888 and SS 898 for 511 and 451/452 into one document

    • Only when “with QC/QA” is specified in the bid item.

  • 451-452 – generally over 10,000 Sq Yd

  • Sets minimum requirements for Contractor’s Quality

    Control Plan (QCP).

  • Project Engineer must review and approve QCP and

    can require changes.

  • Sets the Quality Assurance testing requirements

    for the ODOT Project Staff.

  • Side by side air content – 10% of QC Samples

  • QA strength core for 1 in 10 QC Strength Cores


  • Supplement 1126 1127

    Supplement 1126 / 1127

    S1126 - Developing and Submitting a Portland Cement Concrete Mix Design for Acceptance

    • New supplement for Suppliers submission for JMF.

      S1127 - Pay Factors Determination for Pavement and Structure Concrete

    • Provides direction for pay factor determination and example calculations.
