In search of pavements guaranteeing a level of comfort to users through their serviceability
index, criteria are set, which allow determining a rating according to the state of its structure. For
this, it is very necessary to take into account the methodology that will objectively evaluate their
performance, so that a value can be granted and thus determine the level of serviceability of each
pavement. Through the development of the serviceability models, users are expected to make a
judgment on the quality of the roads, taking as a reference various types of damages and the
inconvenience they cause, but other more field evaluation methods are also used, such as
sampling, damage inventory and expert qualification, as established by the methodology of the
PCI (Pavement Condition Index). Currently there are models designed to be widely applied in
the field of roads, which are deterministic in nature and base their veracity on the criteria of road
users, regardless of the ability or knowledge of these users to make their judgments., which can
generate deviations and errors in the results of the models. The emphasis of this research is to
apply a model that adapts to the conditions of the pavement that is in the city of Barranquilla,
specifically in the north-historical center. When qualifying and determining the serviceability of
pavements in the city, that uses both deterministic and probabilistic models, that includes and
takes into account own factors that impact urban pavements and that can be applied in different
places where there are the same characteristics as in Colombia. The model applied for this study
PCI (Index of condition of the pavement) consists of the visual evaluation of this, having as
reference the 18 damages proposed by the method and based on the results obtained after the
evaluation, a comparative analysis with the operating speeds given in the different sections
