Abstract:
The complex plastic behaviour of the construction material used in the different pavement layers has been one of the main research topics in pavement engineering. The accumulation of permanent strain, permanent deformation, is affected by a mixture of material and load related factors. In this master thesis, several parameters influencing the development of permanent deformation are described and analysed on LTPP-roads in Sweden. The analysis is performed by studying several LTPP-roads in terms of rutting and cracking. The focus of this analysis is to identify the factors that contribute to the unstable behaviour that takes place in the pavement and to investigate the correlation between these factors and the permanent deformation. The analysis concluded that crack index has a major influence on the development of permanent deformation. Therefore, it is recommended that a future deformation prediction models should take into account the parameters such as crack index, subgrade E-modulus and water content of which this master thesis proved to be of much concern.
