Both the catalogue that the MEPDG guide for the design and the road pavement tests are based on the concept of reliability.
To apply the MEPDG to the Italian reality the information contained in C.
The data included in the MEPDG support software were organized into the following three groups: characteristics of the materials, traffic characteristics and climatic conditions.
In this paper, case scenarios simulated using advanced statistical methods are presented and MEPDG was used to determine the results of these case scenarios.
The next step would be to input each scenario in MEPDG and determine expected pavement performance in terms of fatigue cracking, longitudinal cracking, rutting etc.
The proposed alternative, in principle, is to run the MEPDG to develop a response surface and use it to determine the performance for all 7,884 case scenarios through advanced interpolation techniques in n+2 dimensions, n being the number of variables being considered.
It has been also found that the MEPDG does not consider the stiffness reduction of asphalt concrete due to a cumulative damage in the version 0.
Therefore, the models adopted in the MEPDG (Witczak et al.
5 presents the comparison of the max BU fatigue cracking damage obtained by KPDG and MEPDG for 20-year design life.
In order to effectively and efficiently transit to the MEPDG, state Dept of Transportations (DOTs) need a detailed implementation and training strategy.
It is suspected that it will take most states in the USA approx 3 years just to prepare to implement the MEPDG in its current form.
to examine MEPDG design components related to traffic, climate, structural and non-structural elements and provide suitable implementation recommendations for each component;
