Night Paving in Trinidad--Achieving Quality

In 2003, the Airports Authority of Trinidad and Tobago (AATT) began construction of hot mix asphalt (HMA) overlay for Runway 10-28 at Piarco International Airport, Port of Spain, Trinidad. Due to problems with aggregate quality, overlay placement and pilot complaints on runway roughness, the paving works were suspended and the Trinidad and Tobago Civil Aviation Authority (CAA) requested that the U.S. Federal Aviation Administration (FAA) conduct a roughness survey using their airport pavement inertial profiler with their PROFAA analytical software to quantify the extent of the roughness. That survey confirmed that the pavement was rough as characterized by several commonly used roughness indexes, including simulated straight-edge, Boeing Bump Index (BBI), aircraft response, International Roughness Index (IRI), and simulated California Profilograph Index (PI). The FAA also identified several other issues associated with HMA production and placement and recommended that remedial actions be initiated to correct the problems.
