Abstract
Use of proper pavement material for some of intersections need special attention by road designers. At Camp Bondsteel-Kosovo on 2002 were built four road intersections using the concrete as pavement material. Heavy and slow-moving trucks that are turning or accelerating exposed these intersections to some of the highest stress level. After some years this intresections start deteriorating on their surface due to friction. The concrete pavements did not survive this period of usage and after eight years were removed and replaced with asphalt pavements. After more than seven years, the asphalt has shown minor distress but is still in good condition after years of outstanding service. This issue was resolved using aggregate and aggregate blend who meet higher standards. This blend of aggregate has high internal friction developing the degree of interlock needed to resist friction and or shearing. In this case, tough, durable aggregates were necessary, while rounded aggregate avoided in both the coarse and fine fractions. Due to slow-moving traffic on the hot weather, the binder has been selected with higher temperature grade than climate conditions. The asphalt section is still going strong after seven years.
