Rational methods for the dimensioning and auscultation of rigid aeronautical pavements.

Following on from its work on the dimensioning and auscultation of flexible airport pavements, the STAC is developing rational methods for the dimensioning and auscultation of rigid pavements.

Forecast of water heights on runway :

development of the OPHELIA SOFTWARE

Aircraft landing and take-off performance and operational limitations highly depend the runway surface conditions, which can be severely degraded when meteorological conditions are bad.

An airport pavement’s bearing capacity corresponds to its structural capacity to take repeated loads, i.e. accumulated traffic. This parameter is represented in the form of admissible RSI or PCN load.

The historical STAC method (1973-2011) was based on the use of a measuring device unique in the world, the STBA bearing capacity trailer; the test principle consisted of studying the fatigue resistance of the pavement/underlying soil body.
