The quality of the rolling condition of pavements represents an important aspect
for urban mobility, especially on roads and exclusive public transport lanes. The
Pavement Management System (SGP) is an important tool for maintaining the
quality of the urban road network, promoting less use of public resources.
However, the implementation of this system depends on carrying out surveys of
defects present in the pavements. Therefore, the objective of this research is to
evaluate the surface condition of the three-lane pavement with an exclusive lane
in the city of Belém, as well as compare the results obtained for each traffic lane.
To this end, a survey of pavement defects in the study area was carried out and
the ICPs (Pavement Condition Index) of each traffic lane were calculated, based
on the Sousa method (2021), which adapted the SHRP (Strategic Highway
Research Program). Among the main results, the exclusive lanes presented a
lower average ICP than the central lane and the left lane, being, respectively,
78.94, 87.21 and 89.19. The most critical section presented an ICP of 46.05 and
the best sections presented an ICP of 91.67. The most frequent defects in the
study area analyzed were wear (39.78%), permanent deformation (18.23%) and
fatigue cracks (17.13%). In the exclusive lanes, the defects that occurred most
were wear (24.24%), fatigue cracks (22.22%) and permanent deformations
(17.17%). No significant linear correlation was detected between ICP and road
elevation, nor between ICP and the number of bus lines that travel along the lane.
Finally, it was concluded that exclusive bus lanes present a greater degree of
deterioration compared to the others, therefore, they should be prioritized in
maintenance and rehabilitation activities.
