This month, we take a look back at the history of the Kalaeloa Asphalt Terminal and the effect that the terminal has had on the asphalt paving industry in Hawaii. Click here to go to the feature article.
Congratulations 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.
On 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.
HAPI 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.

Women 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).
In early October HAPI member FORTA Corporation was in Hawaii to provide information about their FORTA-FI® high-tensile strength fiber for asphalt pavement that helps pavements perform better and last longer than traditional asphalt placements. On October 3rd, they conducted a workshop in Honolulu. Click here for additional information and photos.
About 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.

ASPHALT HAWAII
KALAELOA ASPHALT TERMINAL
In 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. - 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.
“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.
Another 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. 
As mentioned in the feature article, the three basic mix types – dense-graded, stone matrix asphalt, and open-graded – can all be produced using a modified asphalt. Click here to learn more about these mix types.
The SBS polymer technology used to modify our binder was developed in the 1970s by Houston-based Kraton Performance Polymers Inc. Click here to watch a short video about their company and other uses of polymers.
Asphalt Fact #50: Asphalt has a proven track record when it comes to long life and smoothness. The use of a poly modified binder extends the life of a road. Click here for additional information. | (back to top) | |||

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.
