AIRPORT ASPHALT MIXTURES BEHAVIOUR TO FATIGUE AND PERMANENT DEFORMATION
Last modified: 2017-02-28
In the design of road structures, fatigue and permanent deformations was always the main factors, which had taken into account. Fatigue occurs and develops because of deformation from repeated tensile loads of traffic data which determined tensile stress in road layer; permanent deformations occur due to repeated traffic loads superposed with high temperatures. Both phenomena, fatigue and permanent deformation plays an important role in pavement design.
The objective of this research is to estimate the fatigue behavior and permanent deformations of bituminous mixtures designed for airport, BBA 16 (the design of airport asphalt mix recipe was made by both the Marshall and SUPERPAVE method and framed according to French Norm NF P 98-131, LCPC French Design Manual - 2007 and European Norm SR EN 13108-1), by framed according to European Standard SR EN 12694-24 as "Resistance to fatigue", European Standard SR EN 12694-25 as “Cyclic compression test” and European Standard SR EN 13108-20 as "Type testing".
