105 IAC 10-3-2 Calculation of ESAL values

Authority: IC 8-23-2-6

Affected: IC 9-20

Sec. 2. (a) The ESAL value for each axle group shall be calculated as follows:

(1) The ESAL value for each axle shall be calculated as the actual axle weight, divided by the axle group divisor (as defined in subdivision (4), below), all raised to the fourth power ((weight/divisor)^4). (See the sample equation shown in Figure 1.)

(2) The numerator for each axle group is the sum of the gross axle weights of all individual axles within that axle group, or the combined GAW.

(3) The divisor for each axle group depends on the number of axles in the group.

(4) Divisors shall be as follows:

(A) If the axle group consists of a single axle, the divisor is eighteen thousand (18,000) pounds.

(B) If the axle group consists of a tandem axle (that is, two (2) individual axles), the divisor is thirty-three thousand two hundred (33,200) pounds.

(C) If the axle group consists of a tridem axle (that is, three (3) individual axles), the divisor is forty-six thousand (46,000) pounds.

(D) If the axle group consists of a quad axle (that is, four (4) individual axles), the divisor is fifty-seven thousand (57,000) pounds.

(E) If the axle group consists of a quintuple axle (that is, five (5) individual axles), the divisor is sixty-five thousand (65,000) pounds.

(5) The resultant fraction quantity is raised to the fourth power.

Figure 1. Examples of calculations for a single axle and a tandem axle.

(b) ESAL value for the sum of all axles of the vehicle shall be calculated as follows: (ESAL=Axle1 ESAL+Axle2 ESAL+Axle3 ESAL+ AxleN ESAL). (See the sample calculation shown in Figure 2.) The total vehicle ESAL value is the sum of all axle group ESAL values.

Figure 2. Example of calculation of total vehicle ESAL value.

(c) This section shall apply to all calculations of ESAL values throughout this article.

Authority: IC 8-23-2-6

Affected: IC 9-20

Sec. 3. (a) The department shall set the maximum weight of a vehicle that may be permitted with any overweight load permit (whether divisible or nondivisible). The maximum weight may not exceed the following limitations:

(1) The GAW of the front axles of the truck or tractor power unit shall not exceed:

(A) seventeen thousand six hundred (17,600) pounds; or

(B) eight hundred (800) pounds per inch of tire width measured at the flanges;

whichever is less.

(2) The GAW of all axles other than front axles shall not exceed twenty thousand (20,000) pounds, unless:

(A) the vehicle will operate solely on interstate highways, U.S. highways, or other four (4) lane state highways under the permit; or

(B) if necessary, a vehicle may travel over a two (2) lane state highway to the nearest interstate, U.S. Highways or four (4) lane state highway to reach the permitted destination(s).

In such cases, one (1) tandem axle group may have a GAW of up to forty-eight thousand (48,000) pounds (that is, two (2) axles, each with a GAW not more than twenty-four thousand (24,000) pounds). However, under no circumstances shall the weight carried by any tire exceed eight hundred (800) pounds per inch of tire width measured at the flanges.

(3) The individual axle weight in any axle group shall not vary from other axles in same group by more than two thousand (2,000) pounds.

(4) All tires shall be pneumatic, and no tires shall be permitted to carry a weight greater than that of any tire's manufacturer rated maximum weight.

(b) The department shall set axle spacing requirements for vehicles that may be permitted with any overweight load permit (divisible or nondivisible). The axle spacing on any vehicle for which any overweight load permit is issued shall meet all of the following requirements:

(1) Minimum inner bridge spacing: The inner bridge spacing (the sum of all wheelbases) excluding the front axle shall be at least thirty-six (36) feet.

(2) Minimum outside wheelbase: The outside wheelbase (the sum of all wheelbases) shall be at least fifty-one (51) feet.

Sec. 1. (a) The purpose of this rule is to establish procedures for issuance, fees, and enforcement of overweight divisible load permits.

(b) Permits issued by or on behalf of the department under this rule apply to specified interstate, U.S., and state routes or highways only. Any travel of overweight divisible loads over local routes or highways must be permitted separately by the affected local governments.

(c) By order of the commissioner, the department may temporarily raise the allowable number of single trip permits above the limit specified in IC 9-20-6-2.2 for a calendar year based on the commissioner's determination that any [sic, of] the following apply:

(1) Lack of transportation options for certain resources.

(2) Supply chain interruptions.

(3) Supply dock backlogs.

(4) Due to a natural disaster or military unrest, disruptions to:

(A) food, fuel, or medical supply shipments;

(B) critical materials or supplies; or

(C) other resources that would minimize disruptions.

(5) Acute transportation labor shortages due to a strike.

(6) Other emergency or disaster conditions that may cause imminent and substantial peril to the health, safety, or welfare of the public.

(d) The department shall determine that raising the allowable number of permits will reasonably lead to a resolution of, or reduction in, the number of disruptions or impacts for which the relief is sought. Except when an emergency has been declared by a state or federal agency or official, the need for the order shall be supported by credible resources or with data from publicly available sources, such as the United States Bureau of Labor Statistics, United States Department of Transportation Bureau of Transportation Statistics, or United States Department of Transportation Federal Highway Administration Freight Analysis Framework.

Sec. 3.5. (a) The permit fees collected from issuing divisible load permits are distributed under IC 9-20-6-13(b).

(b) For a permit issued under this rule, an applicant shall pay a twenty dollar ($20) administrative fee in addition to other permit fees as provided under this section.

(c) Divisible load permit fees are calculated as follows:

(1) A legal eighty thousand (80,000) pound, five (5) axle tractor-trailer is measured to have an ESAL value of approximately two and four-tenths (2.4) ESALs, as calculated under 105 IAC 10-3-2. Loads exceeding eighty thousand (80,000) pounds require divisible or nondivisible overweight permits and will be charged for all additional ESALs exceeding two and four-tenths (2.4) ESALs on a per mile basis.

(2) Permitted ESALs for a given permit are the total vehicle ESAL value of the permitted vehicle minus the two and four-tenths (2.4) ESALs allowed by a legal load without a permit (ESAL - 2.4).

(3) ESAL miles are the permitted ESAL value multiplied by the miles to be driven on the route specified in the permit ((ESAL - 2.4) × miles traveled).

(4) The total fee for an individual trip permit is the twenty dollar ($20) administrative fee plus twenty-five cents ($0.25) per ESAL mile above the allowed two and four-tenths (2.4) ESALs ($20 + (($0.25) × (ESAL - 2.4) × (miles traveled)). Permit fees are rounded up to the nearest dollar as follows:

(5) Annual multi-trip permits for vehicles greater than eighty thousand (80,000) pounds and less than two and four-tenths (2.4) total vehicle ESALs are issued at a zero (0) ESAL mile fee and the twenty dollar ($20) administrative fee.

Any permit violation may disqualify the permittee from applying for a new permit for a period of thirty (30), ninety (90), and three hundred sixty-five (365) calendar days for the first, second, and third violation, respectively.
