ABSTRACT
Performing surveys on a
single section of a road is quite different from
that on a road network. In the first case, the need for
performance characteristics of the pavement may be of service to
rehabilitation. Surveying a road network, instead, aims to establish service
levels, identify deficiencies and priorities and define budgets for maintenance.
This challenge needs a methodological approach in order to widen the action
plan and optimize the cost-benefit analysis of each asset through the use of
preventive maintenance policies. High-speed monitoring systems on the market were
specialized towards the necessity of measuring specific performance of the
pavement or mapping land (data inventory).
The technological development of instrumentations such
as inertial systems and synchronizers has enabled the integration of different
devices and the achievement of the best correlation of data. This is the case
of the LARAN (laser road analyzer), whose helpfulness will be presented within
a case study in which geometrical data and surface characteristic information—cracks, texture,
profiles—were obtained through
a unique survey. The cross-analysis resulted efficient for safety purposes and also
for the identification of “black points” corresponding to boundary operative conditions of the
road with respect to technical standards and recommendations.
