HAPI Photo Contest - Winning SubmittalCongratulations to Shelly Nisly of Bowers + Kubota Consulting for submitting the winning photo for this year’s HAPI photo contest.  Nisly submitted a photo of HAPI member Maui Paving, LCC working on the Hana Highway Resurfacing, Paia Town to Hookipa project in Paia Town, Maui.  Click here to see the complete contest results.

HAPI Lunch Meeting - Maui Beach HotelOn October 19th, HAPI held its first lunch meeting on the island of Maui.  Members and guests were treated to a delicious lunch at the Maui Beach Hotel.  The lunch was followed by an update from the HDOT Maui District Office on contractor testing for acceptance.  HAPI executive director Jon Young also gave a presentation about open-graded mixes. Click here for photos and additional information about the meeting. 

High school student with a HAPI sticker on his hard hatHAPI was an exhibitor at the Construction Career Day (CCD) on Oahu, which was conducted on October 25 and 26 at the Aloha Stadium parking lot.  The event was attended by over a thousand students from high schools and other educational institutions on the island.  About 200 students visited our table manned by Jon Young and Lynn Young.

Kirsten Pauley Technical Director Asphalt Pavement Association of Indiana IncWomen of Asphalt (WofA) is a national coalition that supports women in all aspects of the asphalt industry through mentoring, education, and advocacy, and by encouraging women to seek careers in the asphalt industry.  Starting November 5th WofA will be highlighting 100 women within the asphalt industry over 100 days as we countdown to World of Asphalt 2019 Conference and Show in Indianapolis, Indiana February 12-14. The women will be individually featured on the WofA website at www.womenofasphalt.org, Facebook, Twitter and Instagram (womenofasphalt).

On October 3rd, they conducted a workshop in Honolulu.  Click here for additional information and photos.

Tensar workshop at the Ala Moana HotelAbout 30 people attended the "Use of Geosynthetics for Asphalt Pavements" workshop conducted by HAPI member Tensar and their local representative, HAPI member Geotech Solutions, Inc. The 3-hour workshop was conducted on October 9th on Hawaii Island (Hilo) and October 11th on Oahu. The workshops were attended by a good mixture of government agencies, design consultants, and contractors.  Click here for additional information and photos of the workshops.

On October 10th, Jon Young was a guest lecturer for CEE 375 Construction Materials at the University of Hawaii. The lecture provided the students with an introduction to the asphalt industry.  Topics presented included applications of asphalt pavements, Mayor Caldwell’s 5-year repaving plan, pavement types, mix types, basics of mix design, asphalt pavement production, recycling, mill and fill construction, and potholes.

Feature Article


For many years, two local oil refineries in Hawaii supplied asphalt binder (asphalt) to the paving industry  After one of the refineries (Chevron) stopped production of asphalt in 2006, the construction industry began to experience an unstable supply of asphalt from the remaining supplier.  This resulted in periods of as long as six weeks with no available asphalt to meet contractual obligations and to maintain Hawaii’s roads. These shortages caused disruptions in the entire construction industry.

In response to these disruptions, an industry consortium consisting of the largest users of asphalt in Hawaii conducted research to determine the viability of constructing a facility to accept, store, and dispense imported asphalt.  The group determined the undertaking to be feasible and began design and permitting on the project in Spring 2006. They broke ground for the new facility just 15 months later.  After 16 months of construction, the plant was operational and received its first load of asphalt.
The Kalaeloa Asphalt Terminal was designed to facilitate the importation and distribution of liquid asphalt for the Hawaiian Islands.  In this role, the terminal needed to be able to accept asphalt tanker-sized cargos into storage and be able to provide longer term storage, as well as accommodate the loading of trucks and bulk containers for distribution of the asphalt throughout the islands.  With a storage capacity of nearly 300,000 barrels, the project provided a steady supply of consistent-quality asphalt to our construction industry in Hawaii.
Mixing TankIn 2014, the Kalaeloa Asphalt Terminal (Terminal) was upgraded to include polymer modified asphalt (PMA) production.  PMA is an engineered product that improves the viscoelastic properties of asphalt with the addition of a modifier.  One of the most widely-used modifiers for asphalt pavement binders, and the one used at the Terminal, is styrene-butadiene-styrene (SBS) polymer, an elastomer which is a synthetic rubber thermoplastic granulate that can be shaped by heat.  The SBS polymer technology was developed in the 1970s by (HAPI member) Houston-based Kraton Performance Polymers Inc.  The polymer and the asphalt binder are pre-blended at the Terminal (mixing tank is pictured to the right) and then transported to asphalt plants.  
Asphalt binder is modified to achieve the following improvements
  • Increased stiffness of the pavement, which reduces deformation. 
  • Improved recovery of flexible pavements under heavy loads, which reduces rutting and shoving.
  • Lower stiffness and faster relaxation properties at low service temperatures, which reduces thermal cracking. 
  • Increased adhesion between the asphalt binder and the aggregate in the presence of moisture, which reduces the likelihood of stripping.
  • Extended pavement service life.

The DOT Airports Division has been specifying a modified binder for many of their airfield pavements.  The Kalaeloa Terminal supplied modified binder for two projects at the Daniel K. Inouye Airport (HNL) and one project at the Lihue Airport.  “NDWP Widen Taxi Lanes G & L – Phase I,” at HNL “Taxiway Z Structural Improvements,” at HNL used a PG 76-22 modified binder.  “NDWP Widen Taxi Lanes G & L – Phase I,” at HNL used a PG 70-22 modified binder. And most recently, the Terminal supplied a PG 76-22 modified binder with 70% elastic recovery for the Lihue airport resurfacing project.
Fuel resistant asphalt (FRA) is another product that could be considered for airfield pavements. FRA is a viable alternative to coal tar sealers.  FRA was first developed in the Netherlands and has been used at several international airports.  FRA was first used in the United States at La Guardia Airport in New York in 2002 and then as a fuel-resistant apron application at Boston’s Logan International Airport in 2004 and in 2005.  The Kalaeloa Terminal is currently developing a process to produce FRA in anticipation of a project requiring that specification of asphalt binder.   Click here to learn more about this exciting product.
Outside the airports, the Terminal has produced modified asphalt binders for all types of mixtures: dense graded, gap-graded (SMA), and open-graded.  In 2017, the section of Hawaii Belt Road in the Ka’awali’i Gulch was paved using Open-Graded Friction Course (OGFC) to improve both safety (it eliminated splashing) and improve surface friction.  Click here for our newsletter article about this project.
Porous asphalt being placed at Alexander Field, Punahou SchoolAnother type of open-graded mixture is porous asphalt.  One use of this mixture has been to facilitate drainage of an athletic field.  Click here for our newsletter article about the use of porous asphalt for the Alexander Field at Punahou School.  
This mixture also serves as a low impact development (LID) improvement approved for use in the City and County of Honolulu's recently implemented Water Quality Rules.  Porous asphalt, which is a permeable pavement, was featured in a recent HAPI newsletter (click here).  The article discusses the use of porous asphalt for a residential development in Wahiawa.
Since 2014, HAPI has been in discussions with various government agencies about the use of a modified binder in dense graded mixtures.  We have suggested it be used for high volume traffic roads such as King Street, Beretania Street, and Kapiolani Boulevard, Nimitz Highway, and Ala Moana Boulevard.
With the help of HAPI, Asphalt Hawaii will continue to provide the right asphalt binder for the right project.

National Highways Institute: Full Depth Reclamation, or FDR, is a rehabilitation technique in which the full thickness of the asphalt pavement and a predetermined portion of the underlying materials (that is, the base, the subbase, and/or subgrade) is uniformly pulverized and blended to provide an upgraded, homogeneous material.
