Title: Specifying Asphalt Pavement Mixes
Speaker: Jon M. Young, Hawaii Asphalt Paving Industry
It is important that the desired asphalt mix gets specified on the plans and in the specifications. This presentation reviews aggregate gradations and binders used in Hawaii and how they are shown in the plans and specifications.
Title: Envision Rating System
Speaker: Jon M. Young, Executive Director, Hawaii Asphalt Pavement Industry
An overview of Envision rating system, that provides a consistent, consensus-based framework for assessing sustainability, resiliency, and equity in civil infrastructure.
Awarded road, harbors, and airfield projects will be presented as examples.
Title: Intro to Stone Matrix Asphalt (SMA)
Speakers: Jon M. Young, Hawaii Asphalt Paving Industry
This session will introduce Stone Matrix Asphalt (SMA). SMA is a gap-graded hot mix asphalt (HMA) originally developed in Europe to maximize rutting resistance and durability. The mix design goal is to create stone-on-stone contact within the mixture. Since aggregates do not deform as much as asphalt binder under load, this stone-on-stone contact greatly reduces rutting.
Title: Intro to Balanced Mix Design
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry
Balanced Mix Design (BMD) is coming soon to Hawaii. Working together, HDOT and HAPI, moving forward with the implementation.
BMD is an enhanced approach to designing asphalt paving mixtures to achieve a satisfactory balance between rutting resistance and crack resistance. It promises to result in longer lasting asphalt pavements.
This session will cover the basics of BMD and what’s happening in other states.
Title: Pavement Technologies in Hawaii
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry
In recent years, HDOT Highways Division has added the use of PMA and SMA to the tool box of asphalt mixes. They are doing a project with mixes that use a plastic additive and mixes with 50% RAP.
Join us to learn more about these technologies and what HDOT has in store for the future.
A quiz game using Menti.com.
The topics of the questions will be asphalt industry, HAPI, and of course, the holiday season. Prizes will be award to the top five finishers – $25, $20, $15, $10, and $5 gift cards from a wide variety of stores.
