Smoothness 101 (12/02/20) @ Zoom Presentation
Dec 2 @ 11:30 am – 12:30 pm

Title: Smoothness 101
Speaker: Brandon Silva, Vice President, Pavement Management Solutions, Inc.

Our HDOT has a smoothness specification for construction of new and resurfacing of existing asphalt paved roads. This session is an introduction to smoothness and will cover:
– What is pavement smoothness
– What affects pavement smoothness
– Key terms used such as IRI
– Equipment used to measure smoothness
In addition to our speaker, HAPI members Ames Engineering, Inc. and SSI will be on hand for questions and answers.

GPR for In-Place Density (12/09/20) @ Zoom Presentation
Dec 9 @ 11:30 am – 12:30 pm

Title: GPR for In-Place Density
Speaker: Dr. Arudi Rajagopal

The highway engineering community has been routinely using Ground Penetrating Radar (GPR) for many applications including: mapping type and thickness of pavement layers, detection of subsurface voids and subgrade moisture, deterioration in concrete pavements, rebar corrosion surveys, overlay debonding, etc. Recent investigations reveal potential of GPR to estimate density of newly placed asphalt layer. This presentation covers a review of recent and ongoing research, and a field experiment in Ohio to validate the applicability of GPR device for in-place density measurements.

Intro to Stone Matrix Asphalt (12/16/20) @ Zoom Presentation
Dec 16 @ 11:30 am – 12:30 pm

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.
