PIARCO RUNWAY REHABILITATION

The Piarco Airport runway founded on wet clay subgrades had over a number of years developed severe levels of distress. In 1983 partial strengthening was achieved by application of a 4 inch asphalt concrete overlay. The binder used was blended Trinidad lake asphalt. The treatment has to date removed all symptons of distress and the runway exhibits good stability, durability and resistance to skidding and build-up of rubber. This paper was presented at the First World Natural Asphalt Congress in January 1985. (TRRL)
