| Abstract | A study was conducted at Bangkok International Airport to evaluate a new runway pavement using a dynamic non-destructive testing technique. Deflections under a known dynamic force provided the main input data for the evaluation. Several other parameters which affect pavement performance were considered. These included subgrade supporting capability, slab rigidity, characteristic length of the deflection bowl, and the projected traffic.
A pavement section 1000 m long and 60 m wide was
tested. Evaluation of the data was based on the Hertz model
which assumes characterization of the subgrade by its modulus of subgrade reaction and the concrete surface slab by its flexural rigidity. It was found that the Hertz model enabled evaluation of a rigid pavement.
Computations were made to establish the load carrying
capacity for the number of aircraft departures of types
expected during the design life of the pavement. The pavement thickness was found to be adequate with respect to load carrying ability.
Finally, an attempt was made to determine the effect of dynamic force, frequency, and pavement thickness on deflection. The results showed that the deflection depends largely upon the magnitude of the applied force and is inversely, but slightly, affected by the frequency of application of the load. |
