Quoted in Courtney Teague's story in the Honolulu Civil Beat about the poor quality of pavements in Honolulu.

Local asphalt industry expert Jon Young and Panos Prevedouros, professor and chair of the University of Hawaii Civil and Environmental Engineering Department, agree that the city’s methods for filling potholes are cost-effective, but not the longest-lasting.
“Dramatic deterioration” of Oahu’s roads at the turn of the century forced the city and state to be more proactive about maintenance, said Prevedouros, who once ran for mayor on a platform that focused on fixing infrastructure. He said the city — and especially the state — could improve maintenance strategies.
The state paid UH $1 million over about five years for a report by Ricardo Archilla, associate professor of Civil and Environmental Engineering, that looked at ways Oahu could improve its roads and created the recommendations, Prevedouros said.
Though the city did not pay for the report, Prevedouros said it has been quicker to adopt its findings and conduct field assessments.
....
Prevedouros described the city’s pothole repair methods as “amateurish,” but cost-effective.
He pointed to “very durable” European techniques as a superior example, which involve squaring off the edges of a pothole and using heavy trucks to pack the pothole down in 30-40 minutes. There’s no difference in the amount of time taken to fill the pothole, but there is a difference in quality and longevity of the repair — and cost, he said.
Pothole repairs on state roads take place at night, he said, and more time is spent on them because of the higher traffic volumes.
The city usually fixes potholes quickly during the day in 30 minutes to an hour, Prevedouros said. When crews have to leave for the next pothole, he said the new asphalt isn’t completely dry and is already being damaged by traffic.
...
Overall, Prevedouros of the University of Hawaii gave Oahu’s roads a D+ grade. The average lifespan of Hawaii roads is short and the powerful sun poses a constant threat, he said.
Road repaving should be prioritized over pothole repair, he said.
“We have made a business of (repairing potholes),” he said. “…It’s emergency Band-Aids and that’s not a way to run any system … it shows that (the road) is way past deterioration.”
