Airstrip Structural Design Using Roller Compacted Concrete Base

There are traditionally two classifications of airstrip pavements. Structuraldesigns within these classifications are performed using design aircraft with different take-off weights and tire pressures. This paper describes a study of the development of designs for these airstrip classifications using a new pavement structure consisting of roller-compacted concrete (RCC) base under thin asphalt concrete (AC) layer. The structural design index used is the flexural stress at the bottom of the base, and the structural design criterion is that the product of calculated load stress and composite assurance factor should not be greater than flexural strength of RCC. The mechanics of the pavement structures associated with the two airstrip classifications were analyzed using elastic-layer theory analysis. In conclusion, the advised design parameters for two classifications of airstrip pavements are given as reference.
