USING LOCAL MATERIALS SUCH AS CORAL TO IMPROVE A PAVEMENT STRUCRURAL DESIGN - CASE OF THE AERONAUTICAL PAVEMENT IN SAINTE MARIE MADAGASCAR INTERNATIONAL AIRPORT

Geotechnical engineering

The Sainte Marie airport is strategically an economic pillar of the region, and in consequence the country, as one of the few in number international gateway to Madagascar. In fact, its technical characteristics, in addition to financial or environmental aspects, is more than important, as far as it should met international recognized standards. Knowing that the airport was originally built and met air transport requirements according to ATR 42 aircraft, until 2006. The admission of new aircraft such as ATR 72 requires on the one hand the questioning of the aerodrome lift and on the other hand the lengthening of the runway. This manuscript focuses on the evaluation of the bearing capacity of the aeronautical pavement referring to ACN/PCN method, in order to propose variants for the project realization. The study was conducted in order to adding a new coral layer in the structure of the aeronautical pavement, as coral is a local material, available in large quantity at least on the seashores of the area, and should be valued accordingly. The structural design of the aeronautical pavement uses the total equivalent thickness "e" for a platform wich there Californian Bearing Ration “C.B.R.” was given, taking into account the maximum loading of the aircraft. In fact, our research and analysis is expected to lead up to a conclusion, demonstrated by a scientific reasoning, and in the ground, practical of constructing, renovating, repairing and maintaining infrastructure, especially in remote location where supplying material is not always an evidence.
