Connector Condition
This is a key element in the serviceability of a connector which can affect
the speed of travel, and in the case of poor pavement condition, can cause
damage to the vehicle and its contents. The rating of pavement was broken into
five categories, primarily based on the speed that the truck could comfortably
travel (See Exhibit C-1).
Exhibit C-1. Pavement
Rating Categories
For all the connectors inventoried, about half were considered good or very
good, 37 percent were rated as fair, and 12 percent were rated as poor or very
poor. The average for all of the NHS with poor/very poor rating is 8 percent.
Fair pavements would be considered due for resurfacing and poor and very poor
are past due for resurfacing and possibly reconstruction. Pavement condition by
terminal type was also calculated.
While airports and pipelines were about average with 7 percent in the poor
and very poor categories, rail/truck and ports showed 12 percent and 15 percent
respectively. The poor and very poor rating are important because they cause
reductions in the speed and efficiency of a facility and may also damage the
vehicle and its contents (See Exhibit C-2).
