Warm Mix Asphalt Technologies Evaluation Program

National Transportation Product Evaluation Program (NTPEP)

• National evaluation program of products and materials

• Evaluations provide single source testing of common products and materials used by DOTs

• Provides a public-private partnership that prevents duplication of effort

• Currently evaluates over 25 product types

• All states & territories have access to data

Benefits of using NTPEP for Manufacturers

• Avoid time and expense of repeated evaluations

• Product exposure

• Raise the bar

• Contribute to work plan development

• Opportunity to voice concerns

• Build DOT Relationships

NTPEP Websites

• www.ntpep.org

– General NTPEP information, NTPEP Usage Map, Operations Guide

– Work plans, committee rosters, meeting minutes

• DataMine (data.ntpep.org)

– Submit evaluation applications, invoice tracking, data upload and review

– Interested producers should register

NTPEP Websites

• DataMine 2.0

– Will only be used for submitting applications and processing invoices for the WMA Program

• DataMine 3.0 (ETA 2016)

– WMA module still being developed

– Testing data will be uploaded here

– Several improvements are being implemented

• “Data Link” – Easy way to link states to your data

WMA Technologies Committee

• Chair – Jack Cowsert, North Carolina DOT

• Vice Chair – Barry Paye, Wisconsin DOT

• 11 states and FHWA currently represented in committee

• Room for 2-3 industry members “Voice of Industry” – Can provide input but can’t vote on work plan changes

– Ideally would like different technologies represented

• Quarterly conference calls and session at annual NTPEP meeting

WMA Technologies Program

• Evaluation of chemical and organic additives, foaming, and other technologies as applicable

• Laboratory comparison testing between HMA control and WMA samples – Intent is to verify that WMA Technology perform at least as

well as HMA control

– Not intended to investigate relative WMA technology performance

– States can use data for qualification of technologies

• Florida DOT is the NTPEP designated laboratory

Laboratory Produced WMA Technologies

• Technologies that can be reproduced in a laboratory setting

• One control HMA mix will be used for comparison to all laboratory produced WMA technologies

– Details of control mix shall be made available to producers

• Cost = $4,500 per product

– Includes cost of materials, WMA testing, control HMA testing, and maintaining DataMine

Plant Produced WMA Technologies

• Technologies that can’t be reproduced in a laboratory setting

• Separate control HMA mix for each product

– HMA and WMA sampled at plant by NTPEP representative

– Shipped to FLDOT for lab testing

• Cost = $11,500 per product

– Includes cost of WMA testing, control HMA testing, and maintaining DataMine data

WMA Laboratory Testing Scope

• Aggregate Properties – Gradation, specific gravities, F&E, Sand Eq., FAA, CAA, Soundness, LA

Wear, and Micro Deval

• Asphalt Properties – Continuous grading of asphalt binder, warm mix modified asphalt

binder, and extracted binder (plant produced only)

• HMA/WMA Volumetric Properties

• HMA/WMA Performance Properties – Hamburg, Dynamic Modulus, and TSR

NTPEP WMA Testing Cycle

• Submission cycle opens on October 1st and runs through December 18th

– Email notification will be sent out with more information

– Submit applications through DataMine • Application will collect information on technology including mixing

instructions, technical literature, and MSDS

• Sampling and testing to begin in early 2016

• Data available after all lab testing is complete

• Test data is good for 7 years

– Formulation changes require retest

Questions?

NTPEP Warm Mix Asphalt (WMA) Technologies Introduction www.ntpep.org data.ntpep.org

Becky Smith MDSHA

o No difference made between a dense grade type for the grade type

o Going with one standard EVO grade mix

BG67

o Gap graded warm is the number one request for Maryland

Raises a concern

Larry - Oregon DOT

o Pucks? – what is the process

Taking the foamed asphalt and heating it up to volumetric temperatures for

testing

Florida Question

o Design usually gets placed in a binder that is typical to that state

The binder is made to be a part of the first step in gaining approval by utilizing

NTPEP
