LONG-TERM ASPHALT CONCRETE SERVICEABILITY STUDY

This evaluatory study of the service performance of several asphalt concrete pavements distingushed between the changes which occur with age and those caused by traffic. The principal physical characteristics were evaluated at the time of construction to provide a base for measurement of progressive changes. The projects on which the test points were located were selected to provide a geographical distribution representing the different climatic characteristics prevalent in the state. The sampling procedure is outlined. At the conclusion of the 10-year period of sampling and testing, the values were tabulated for each property for each six-month interval of time. A stepwise regression analysis program was utilized. The study results are detailed. Observations (listed) made during the study led to changes in pavement structure and asphalt concrete mix design.
