PAVEMENT DATA
7-1-0
General Information
**ON A/C A320-200 A320neo
General Information
1.
A brief description of the pavement charts that follow will help in airport planning.
To aid in the interpolation between the discrete values shown, each aircraft configuration is shown
with a minimum range of five loads on the Main Landing Gear (MLG).
All curves on the charts represent data at a constant specified tire pressure with:
-
The aircraft loaded to the Maximum Ramp Weight (MRW),
-
The CG at its maximum permissible aft position.
Pavement requirements for commercial aircraft are derived from the static analysis of loads imposed
on the MLG struts.
Landing Gear Footprint:
Section 07-02-00 presents basic data on the landing gear footprint configuration, MRW and tire sizes
and pressures.
Maximum Pavement Loads:
Section 07-03-00 shows maximum vertical and horizontal pavement loads for certain critical
conditions at the tire-ground interfaces.
Landing Gear Loading on Pavement:
Section 07-04-00 contains charts to find these loads throughout the stability limits of the aircraft at
rest on the pavement.
These MLG loads are used as the point of entry to the pavement design charts which follow,
interpolating load values where necessary.
Flexible Pavement Requirements - US Army Corps of Engineers Design Method:
Section 07-05-00 uses procedures in Instruction Report No. S-77-1 ”Procedures for Development of
CBR Design Curves”, dated June 1977 and as modified according to the methods described in ICAO
Aerodrome Design Manual, Part 3. Pavements, 2nd Edition, 1983, Section 1.1 (The ACN-PCN
Method), and utilizing the alpha factors approved by ICAO in October 2007.
The report was prepared by the ”U.S. Army Corps Engineers Waterways Experiment Station, Soils
and Pavement Laboratory, Vicksburg, Mississippi”.
The line showing 10 000 coverages is used to calculate the Aircraft Classification Number (ACN).
Flexible Pavement Requirements - LCN Conversion Method:
Page 1
May 01/16
7-1-0
@A320
AIRCRAFT CHARACTERISTICS - AIRPORT AND MAINTENANCE PLANNING
The Load Classification Number (LCN) curves are no longer provided in section 07-06-00 since the
LCN system for reporting pavement strength is obsolete, having been replaced by the ICAO
recommended ACN/PCN system in 1983.
For questions regarding the LCN system, contact Airbus.
Rigid Pavement Requirements - PCA (Portland Cement Association) Design Method:
Section 07-07-00 gives the rigid pavement design curves that have been prepared with the use of the
Westergaard Equation.
This is in general accordance with the procedures outlined in the Portland Cement Association
publications, ”Design of Concrete Airport Pavement”, 1973 and ”Computer Program for Airport
Pavement Design” (Program PDILB), 1967 both by Robert G. Packard.
Rigid Pavement Requirements - LCN Conversion:
The Load Classification Number (LCN) curves are no longer provided in section 07-08-00 since the
LCN system for reporting pavement strength is obsolete, having been replaced by the ICAO
recommended ACN/PCN system in 1983.
For questions regarding the LCN system, contact Airbus.
ACN/PCN Reporting System:
Section 07-09-00 provides ACN data prepared according to the ACN/PCN system as referenced in
ICAO Annex 14, ”Aerodromes”, Volume 1 ”Aerodrome Design and Operations” Fourth Edition, July
2004, incorporating Amendments 1 to 6.
The ACN/PCN system provides a standardized international aircraft/pavement rating system
replacing the various S, T, TT, LCN, AUW, ISWL, etc., rating systems used throughout the world.
ACN is the Aircraft Classification Number and PCN is the corresponding Pavement Classification
Number.
An aircraft having an ACN less than or equal to the PCN can operate without restriction on the
pavement.
Numerically the ACN is two times the derived single wheel load expressed in thousands of kilograms.
The derived single wheel load is defined as the load on a single tire inflated to 1.25 MPa (181 psi)
that would have the same pavement requirements as the aircraft.
Computationally the ACN/PCN system uses PCA program PDILB for rigid pavements and S-77-1 for
flexible pavements to calculate ACN values.
The Airport Authority must decide on the method of pavement analysis and the results of their
evaluation shown as follows:

For flexible pavements, the four subgrade categories (CBR) are:
- A. High Strength
CBR 15
- B. Medium Strength
CBR 10
- C. Low Strength
CBR 6
- D. Ultra Low Strength
CBR 3
For rigid pavements, the four subgrade categories (k) are:
- A. High Strength
k = 150 MN/m3 (550 pci)
- B. Medium Strength
k = 80 MN/m3 (300 pci)
- C. Low Strength
k = 40 MN/m3 (150 pci)
- D. Ultra Low Strength
k = 20 MN/m3 (75 pci)

Landing Gear Loading on Pavement
This section provides data about the landing gear loading on pavement.
The MLG loading on pavement graphs are given for the weight variants that produce (at the MRW
and maximum aft CG) the lowest MLG load and the highest MLG load for each type of aircraft.
Example, see FIGURE 7-4-0-991-009-A, calculation of the total weight on the MLG for:
-
An aircraft with a MRW of 66 400 kg (146 375 lb),
-
The aircraft gross weight is 49 000 kg (108 025 lb),
-
A percentage of weight on the MLG of 95.0% (percentage of weight on the MLG at MRW and
maximum aft CG).
The total weight on the MLG group is 46 550 kg (102 625 lb).
NOTE : The CG in the figure title is the CG used for ACN/LCN calculation.

Flexible Pavement Requirements - U.S. Army Corps of Engineers Design Method
**ON A/C A320-200 A320neo
Flexible Pavement Requirements - US Army Corps of Engineers Design Method
1.
This section provides data about the flexible pavement requirements.
The flexible pavement requirement graphs are given at standard tire pressure for the weight variants
producing (at the MRW and maximum aft CG) the lowest MLG load and the highest MLG load for
each type of aircraft.
They are calculated with the US Army Corps of Engineers Design Method.
To find a flexible pavement thickness, you must know the Subgrade Strength (CBR), the annual
departure level and the weight on one MLG.
The line that shows 10 000 coverages is used to calculate the Aircraft Classification Number (ACN).
The procedure that follows is used to develop flexible pavement design curves:
-
With the scale for pavement thickness at the bottom and the scale for CBR at the top, a random
line is made to show 10 000 coverages,
-
A plot is then made of the incremental values of the weight on the MLG,
-
Annual departure lines are made based on the load lines of the weight on the MLG that is shown
on the graph.
Example, see FIGURE 7-5-0-991-009-A, calculation of the thickness of the flexible pavement for
MLG:
-
An aircraft with a MRW of 66 400 kg (146 375 lb),
-
A ”CBR” value of 10,
-
An annual departure level of 15 000,
-
The load on one MLG of 20 000 kg (44 100 lb).
The required flexible pavement thickness is 44.4 cm (17 in).
NOTE : The CG in the figure title is the CG used for ACN calculation.

Rigid Pavement Requirements - Portland Cement Association Design Method
**ON A/C A320-200 A320neo
Rigid Pavement Requirements - Portland Cement Association Design Method
1.
This section provides data about the rigid pavement requirements for the PCA (Portland Cement
Association) design method.
The rigid pavement requirement graphs are given at standard tire pressure for the weight variants
producing (at the MRW and maximum aft CG) the lowest MLG load and the highest MLG load for
each A/C type.
They are calculated with the PCA design method.
To find a rigid pavement thickness, you must know the Subgrade Modulus (k), the permitted working
stress and the weight on one MLG.
The procedure that follows is used to develop rigid pavement design curves:
-
With the scale for pavement thickness on the left and the scale for permitted working stress on
the right, a random load line is made. This represents the MLG maximum weight to be shown,
-
A plot is then made of all values of the subgrade modulus (k values),
-
More load lines for the incremental values of the weight on the MLG are made based on the
curve for k = 150 MN/m3, which is already shown on the graph.
Example, see FIGURE 7-7-0-991-011-A, calculation of the thickness of the rigid pavement for the
MLG:
-
An aircraft with a MRW of 66 400 kg (146 375 lb),
-
A k value of 80 MN/m3 (300 lbf/in3),
-
A permitted working stress of 31.64 kg/cm2 (450 lb/in2),
-
The load on one MLG is 25 000 kg (55 125 lb).
The required rigid pavement thickness is 230 mm (9 in).
NOTE : The CG in the figure title is the CG used for ACN calculation.

ACN/PCN Reporting System - Flexible and Rigid Pavements
**ON A/C A320-200 A320neo
Aircraft Classification Number - Flexible and Rigid Pavements
1.
This section provides data about the Aircraft Classification Number (ACN) for an aircraft gross
weight in relation to a subgrade strength value for flexible and rigid pavement.
The flexible and rigid pavement requirement graphs are given at standard tire pressure for the weight
variants producing (at the MRW and maximum aft CG) the lowest MLG load and the highest MLG
load for each type of aircraft.
To find the ACN of an aircraft on flexible and rigid pavement, you must know the aircraft gross
weight and the subgrade strength.
NOTE : An aircraft with an ACN equal to or less than the reported PCN can operate on that
pavement, subject to any limitation on the tire pressure.
(Ref: ICAO Aerodrome Design Manual, Part 3, Chapter 1, Second Edition 1983).
Example, see FIGURE 7-9-0-991-013-A (sheet 1), calculation of the ACN for flexible pavement for:
-
An aircraft with a MRW of 66 400 kg (146 375 lb),
-
An aircraft gross weight of 55 000 kg (121 250 lb),
-
A medium subgrade strength (code B).
The ACN for flexible pavement is 28.
Example, see FIGURE 7-9-0-991-013-A (sheet 2), calculation of the ACN for rigid pavement for:
-
An aircraft with a MRW of 66 400 kg (146 375 lb),
-
An aircraft gross weight of 55 000 kg (121 250 lb),
-
A medium subgrade strength (code B).
The ACN for rigid pavement is 32.
2.
Aircraft Classification Number - ACN table
The tables in FIGURE 7-9-0-991-012-A and FIGURE 7-9-0-991-016-A provide ACN data in tabular
format similar to the one used by ICAO in the ”Aerodrome Design Manual Part 3, Pavements -
Edition 1983” for all the operational weight variants of the aircraft.
As an approximation, use a linear interpolation in order to get the ACN at the required operating
weight using the following equation:
-
ACN = ACN min + (ACN max - ACN min) x (Operating weight - 42 000 kg)/(MRW - 42 000
kg)
As an approximation, also use a linear interpolation in order to get the aircraft weight at the
pavement PCN using the following equation:
-
Operating weight = 42 000 kg + (MRW - 42 000 kg) x (PCN - ACN min)/(ACN max - ACN
min)
With ACN max: ACN calculated at the MRW in the table and with ACN min: ACN calculated at 42
000 kg.
