Abstract
The runway structure performance of airports is an important factor for airfields safety and durability. Runway structure durability is straightly related to the thickness of pavement layers and wheel loads submitted to the pavement, where good pavement conditions improve the feasibility of the runway condition for operations. Good conditions of airfield pavements can be assessed with nondestructive tests (NDT), the use of Heavy Weight Deflectometer (HWD) can be conducted to estimate the pavement life by measuring the surface deflections, simulating the impact of massive aircrafts wheels, preserving the integrity of the structure. This study analyzed an airfield pavement condition with HWD deflections, with loads varying between 80 and 260 kN with nine sensors measuring the deflection up to 210 centimeters away from the load center. The pavement deflections were correlated with geotechnical investigations to evaluate the shape bowl basin and the condition of different layers within the structure, also a temperature correction was calculated on the lanes with the most unfavorable condition to evaluate how temperature interfere the pavement performance. Results showed that non-destructive tests with HWD provides plenty information to evaluate airfield pavement conditions.
