Abstract

Sub grade strength, bitumen content of different structural layers and riding quality of wearing surface are the most important factors that affect the overall performance of pavement so it is necessary to evaluate the structural behavior and surface characteristics of pavement. The study reveals that runway of new Benazir Bhutto International Airport Islamabad will behave under the heavy loading of aircrafts as per design requirements. This paper documents the Sub grade CBR tests, field density test, different layer's soil classification, profilograph tests and skid resistance tests were performed to find out structural performance of main runway, secondary runway and taxiway and then compared with internationally design standards. From this research, it was concluded that new BBIAP is properly designed according to specifications. IRI values of main, secondary and taxiway are 1.54, 1.99 and 2.96 respectively which are well within internationally accepted values. Optimum asphalt content of bitumen wearing and bitumen base courses are 5.10% and 4.50% respectively when tested on different samples by extraction tests. Loss of stability in Bitumen wearing course and Bitumen Base course are 18% and 9% respectively. It was also concluded that the best Soil used in sub grade of any pavement is A-2-4 with 95% compaction achieved. Because A-2-4 soil can bear maximum load with respect to other groups soil, it is considered to be very effective while preparing sub grade in any runway pavement. From this research, it was also concluded that the factor of percentage of bitumen is dominating factor in the behavior of resilient modulus at a certain limit, as we increase the percentage of bitumen resilient modulus increases and vice versa. After a certain limit resilient modulus decreases by increasing bitumen content.
