Abstract:

Frequent repair of damage in busy runways and taxiways can be time consuming and costly for airport pavements. Moisture damage has been a persistent problem in some areas of the Logan International Airport in Boston, Massachusetts. In the past Massachusetts Port Authority (Massport) has tried to prevent this problem by modifying the FAAP401 specification to include a higher retained tensile strength for their Hot Mix Asphalt, HMA. In view of those unsuccessful attempts, Massport has started a project in the recent past to conduct a study to recommend changes in their specification to produce more durable mixes. The objective of this paper is to summarize this project and the resultant recommendations. The TSR test alone is not a good indicator of performance for local mixes. The effectiveness of hydrated lime in reducing moisture damage at high temperature has been demonstrated in the study. Mixes containing about eighteen percent of Recycled Asphalt Pavement, RAP, were found to perform adequately but quality control is a concern due to varying sources of RAP. Multiple cycles of freeze thaw were found necessary to identify moisture susceptible mixes. Finally, an accelerated loading test was found to be effective in identifying good and poor performing mixes. It has been recommended that hydrated lime be used in paving mixes, recycled asphalt pavement material not used, the tensile strength test be run after six cycles of freeze thaw and supplemented with an accelerated loading test to be conducted for paving mixes before accepted for placement. Accelerated loading test result limits for acceptance were established on the basis of tests conducted on good and poor performing field cores. The feasibility of producing a desirable mix, conforming to these limits, with locally available materials was confirmed.
