Crown Point Airport - Tobago, West Indies
The 45 m wide runway at the Crown Point International Airport was extended in 1990 to 3,000 m using a 33 % TLA dosage to a 60/70 pen grade asphalt cement in a dense graded aggregate mix. The previous 2,000 m runway was overlaid with 100 mm of mix while the new 1,000 m had a 100 mm asphaltic base topped with a 100 mm surfacing. The pavement has a good subgrade support and is performing remarkably well in its early life. So far, over the past four years there has been no expenditure on structural maintenance after some 2000 equivalent departures of a Boeing 747.
