Hw specs for hma airport pavement

HW Specs For HMA Airport Pavement

PROJECT OVERVIEW

[AAPTP Project 06-05]

DELIVERABLE: Comprehensive Guide for Practicing Airport Designers

How to Modify SSHP Specs

For Acceptable SSAP Specs for HMA Projects

[<60,000# Aircraft Gross Weight]

FINAL REPORT – May, 2009

HW Specs For HMA Airport Pavement

DEFINITIONS

“StateStandard Highway Pavement (SSHP)” specifications – SSHP specifications is used throughout this document to identify the current State specifications for HMA highway pavements covering materials, mix design and selection, manufacture, transport, placement, compaction and acceptance of HMA pavement as well as the contractor’s quality control plan and requirements.

“State Standard Specifications Manual (SSSM)” - SSSM is used throughout this document to identify the current edition of the State Standard Specifications of Highway Construction, State Standard Specifications for Transportation Systems, State Standard Specification for Road and Bridge Construction, or any other title used for a SSSM.

“State Standard Airport Pavement (SSAP)” specifications – SSAP specifications is used throughout this document to identify a State specifications for HMA airport pavements developed in accordance with the guidance provided by AC 150/5100-13A and submitted for FAA approval. The SSAP must comply with critical requirements for airport pavements and instructions on how to reference, or insert, portions of SSHP specifications.

HW Specs For HMA Airport Pavement

Using SSHP Specifications

VS

FAA Item P-401 or P-401 (SP) Specifications

CONSIDERATIONS: GA PAVEMENT <60,000#

Low Traffic Volume

Distress Types: Almost Exclusively Environmental

Foreign Object Damage (FOD)

BENEFITS

High Quality Construction [Familiarity]

More Economical Pavement [vs P-401]

Long Term Performance [Updated Technology]

APPROACH

Draft FAA Engineering Brief (EB)

Interim Guidance to Develop SSAP Specs

Optimize Use of SSHP Specs [Provisions]

Comply with All SSSM Sections, as Applicable

FOR

Aircraft Gross Weight , <60,000#

AND

Address Critical Elements for Airfield Pavements

Employ Marshall and/or Superpave Mixtures

Draft eb xx the guideline3

Draft EB-XX – “The Guideline”

Mix Composition

If State Spec Uses Marshall

50 Blows for Traffic Level A or B

Gradation: use P-401 or P-403 [Bands]

If State Spec Uses Superpave

50 gyrations (Traffic Lev A) or 65 gyrations (Traffic Lev B)

Gradation: AASHTO M-323 [Control Points]

Mix Selection

Base/Intermediate Course: 37mm, 25mm or 19mm

Leveling Course: 12.5mm or 9.5mm

Surface Course: Fine-graded only 19mm or 12.5mm

RAP Limits (per AAPTP 05-06)

15-30% depending on whether surface or base mix, and on recovered PG grade of RAP binder

JMF Submittal Requirements

SSHP Specs sufficient

Draft eb xx the guideline4

Draft EB-XX – “The Guideline”

Construction

Plants and equipment

Rely on SSHP spec

Mandatory test section requirements

On initial production lot of SSHP

Grooving criteria (if shown on plans)

¼” wide x ¼” deep at 1.5” c-c spacing

Amend SSHP

High quality longitudinal joints a must!

Amend SSHP for joint density

Follows Format of Most State Specifications


Draft eb refined and validated

Draft EB Refined and Validated

  • 10 Different State Test Cases

    • AI Regional Engineers developed SSAP specs by applying the Draft EB to their respective SSHP spec

  • Draft EB improved & validated thru this process

  • SSAPs were developed for:

    • FL, MN, PA, TX, VA, CA, MT, OH, WA, MO

      • In Appendices of Final Report

      • Not official SSAPs, but examples

  • Final Report Documents Project [www.aaptp.us]

    • 58 pages total

      • Last 17 pgs is the Final Draft FAA Engineering Brief

    • Appendices are several hundred pages
