load classification number


load classification number
A system of classification of the supporting capacity of pavements, indicating their ability to support loads without cracking or becoming permanently deformed. The number is obtained by making plate-bearing tests on the pavement. Likewise, the equivalent single-wheel load of any aircraft can be expressed in terms of LCN. LCN is dependent on the gear geometry, tire pressure, and the composition and thickness of the pavement. Thus, if the LCN of an airfield pavement is larger than the LCN of the aircraft, the aircraft can safely use the pavement. To express the capacity of pavement as a single number, the standard load classification was introduced (shown in the table).
