The aim of the present research study is to produce a methodology that provides an understanding
of the mechanical behaviour of ballast and its degradation in order to reflect field performance of different
ballast materials used by CAMRAIL in their railway network, and to better anticipate an efficient planning of
the railway track maintenance. Based on existed literature, on collected data of different railway sections, and
on the finite element analysis of the vehicle-track mechanical interaction, a preventive ballast cleaning and
renewal strategy, formulated through ballast deterioration indexes is proposed. Comparing to the ongoing dayto-
day maintenance strategy the proposed functionality-based preventive maintenance offers the following
advantages: security and comfort of users; forecasting of ballast corrective measures; planned maintenance
actions; higher functional and exploitation level of the track and availability of needed materials and
mechanisms. The administration of CAMRAIL has promised to extend further the findings of this work in other
to fully optimized the track maintenance cost in each railway section.
Key words: Ballast deterioration, ballast renewal, critical state, rail-vehicle interaction, threshold index, wear rate,
