Random Sampling Locations (03/03/21) @ Zoom Presentation
Mar 3 @ 11:30 am – 12:30 pm
Title: Random Sampling Locations
Speaker: Jon M. Young, Hawaii Asphalt Paving Industry
The purpose for sampling is to obtain an uncontaminated and representative sample of the material. Proper sampling is just as important as proper testing. Only a small portion of the total material placed is tested, so samples represent large investments. Samples must be randomly obtained. This session will review the methodology used by HDOT for randomly determining the sampling location of uncompacted mix and cores from the mat, and location of cores along the longitudinal joint.
Introduction to Open-Graded Mixes (03/10/21) @ Zoom Presentation
Mar 10 @ 11:30 am – 12:30 pm

Title: Intro to Open-Graded Mixes
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry

An Intro to Open-Graded Mixes will answer the following questions:
– What are open graded mixes?
– Differences from dense graded mixes?
– Where have they been used in Hawaii?
– Where could they be used in the future?
– What’s next?

Understanding a Job Mix Formula Submittal Workshop – Virtual 3/11/21 @ HAPI Office
Mar 11 @ 8:30 am – 10:30 am

Click here to register

Speaker: Jon M. Young, PE, Hawaii Asphalt Pavement Industry

Who Should Attend: Contractors, engineers, and construction managers unfamiliar with a JMF submittal.

The job mix formula (JMF) is the recommended mixture, which includes aggregate gradation and asphalt binder type, to meet the project specifications. The JMF submittal is prepared by the paving contractor for any project that requires the construction of an asphalt pavement. The submittal is typically reviewed by the engineer of record.

This 90 to 120-minute, including questions and answers, workshop will discuss 1) the basics of asphalt pavement mixes, by discussion the Marshall method, which is the most widely used in Hawaii, 2) the production of asphalt pavements, and 3) how the JMF submittal relates to the project specification, using the Department of Transportation, 2005 Standard Specifications as an example.

– A basic understanding of asphalt pavement mixes
– A basic understanding of how asphalt pavements are produced
– An understanding of how to review the JMF submittal for conformance to a specification

Certificate Provided: 2.0 PDHs are available for attending this workshop.
Parking: Parking in front of the building

Modified Binders 101 (03/17/21) @ Zoom Presentation
Mar 17 @ 11:30 am – 12:30 pm
Title: Modified Binders 101
Speaker: Chris Lubbers, Technical Sales and Market Development Manager, Kraton Polymers US, LLC

In this session you will gain an understanding of the difference mixes that could be produced with a modified binder and what are the commonly used modifiers. The session will close with what modifier(s) is used in Hawaii and what agencies use mixes with modified binder.

Intro to Void Reducing Asphalt Membrane (03/24/21) @ Zoom Presentation
Mar 24 @ 11:30 am – 12:30 pm
Title: Intro to Void Reducing Asphalt Membrane
Speakers: Tim Zahrn, Specialty Products Area Manager and Todd Thomas, Technical Director–Specialty Products, both with Asphalt Materials, Inc.

Void Reducing Asphalt Membrane (VRAM) has been used to improve the performance of HMA longitudinal joints. In this session you will learn about VRAM and how it works to improve longitudinal joints. Topics include the technology behind VRAM, methods of application, and key specification items. The types of pavement surfaces and the various joint scenarios will also be discussed.

Use of Color in Communications (03/31/21) @ Zoom Presentation
Mar 31 @ 11:30 am – 12:30 pm

Use of Recycled Materials in Pavements (04/07/21) @ Zoom Presentation
Apr 7 @ 11:30 am – 12:30 pm

Title: Use of Recycled Materials in Pavements
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry

Can Hawaii construct “sustainable roads” using waste tires, plastic, glass, shingles, and old road pavement likely bound for landfill? Join us to learn about these potential recyclable materials and the status of their use in asphalt pavements on the mainland in Hawaii.

Intro to High Friction Surface Treatments (04/14/21) @ Zoom Presentation
Apr 14 @ 11:30 am – 12:30 pm

Title: Intro to High Friction Surface Treatments
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry

High-Friction Surface Treatment (HSFT) is not a new product, but it is something relatively new to streets and highways in Hawaii. What is a HFST, where is it used, and how is it installed? Learn how a HSFT improves the safety of the road.

Pavement Distress (04/21/21) @ Zoom Presentation
Apr 21 @ 11:30 am – 12:30 pm

Title: Pavement Distresses
Speaker: Mike Huner, Engineering Consultant, Huner Consulting, LLC

This session will discuss the FHWA’s LTPP Distress Identification Manual. Attendees will learn the definitions/descriptions, severity levels, and how to measure the various distresses. It is not always possible to identify the causes of the distress by only an observation of the pavement surface. The session will note items that may be indicative of the cause.

Intro to Perpetual Pavements (04/28/21) @ Zoom Presentation
Apr 28 @ 11:30 am – 12:30 pm

Title: Intro to Perpetual Pavements
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry

This session is an overview of the design of perpetual pavements. Since 2001, the APA’s Perpetual Pavement Award program has recognized over 150 long-life pavements in 31 U.S. states and one Canadian province. These roads were all at least 35 years old when honored and had never experienced a structural failure. To qualify, a road could not have had more than 4 inches of new material added over the previous 35 years, and it could not have been resurfaced more frequently than once every 13 years.
