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.
