A.
Except as provided under
R17-6-211
and
R17-6-212,
the Department shall use the formulas and computations provided under Tables
3.01 through 3.09, and Illustration 3, to determine the maximum weights allowed
on any combination of axles within the distance between the front and rear axle
of a given axle group, up to a maximum of 18 feet, when issuing an oversize or
overweight special permit for a non-reducible vehicle or load under this
Article.
B.
The Department shall use the computations provided
under
R17-6-212,
Table 7, to determine the maximum weights allowed for tridem axle group
configurations subject to conditions, restrictions, allowances, and route
limitations provided under
R17-6-212,
Table 6.
A. Except as
provided under
R17-6-212,
an applicant requesting an envelope or special permit under this Chapter for
transporting a nonreducible overweight or oversize and overweight vehicle,
combination of vehicles, or vehicle and load combination shall use the formulas
and computations provided under Illustration 3 and Tables 3.01 through 3.09 to
determine the maximum weights allowed on any combination of axles spaced within
a maximum distance of 18 feet between the front and rear axle of each axle
group.
B. The formulas and
computations provided under Illustration 3, and Tables 3.01 through 3.09, are
an expansion of the federal bridge formula provided under A.R.S. §
28-1100
for use by the Department when issuing an overweight or oversize and overweight
envelope or special permit for movement of a non-reducible vehicle or load
under this Chapter.
C. The axle
group weights provided under Illustration 3, and Tables 3.01 through 3.09,
represent the maximum weights allowed on any combination of axles spaced within
a distance of up to 18 feet between the front and rear axle of any given group.
The values in Table 3.01 line "A" are an expression of the formula W = 1.5 x
700 (L + 40) for L = 3' 5" to 18' 0", where L is the distance between the
centers of the front and rear axles of an axle group. The values in line "B"
and in the remaining Tables are calculated by applying the percentages provided
in the Table footnotes to increase the allowable weights based on wider axle
width and an increased number of tires. Measured axle widths are rounded down
to the nearest 3" increment when determining the appropriate Table to
use.
