Load classification:

In accordance with Table 5.1.

Loading condition	Class D (heavy duty)
Application	All road hierarchy classification
Nominal wheel load (kg)	8000
Serviceability design load (kN)	140
Ultimate limit state design load (kN)	210

Table 5.1 – Load classification

Note: The load classification table is in accordance with AS 3996.

Test loads:

All kerb adaptors shall be designed to load class D (heavy duty) in accordance with Table 5.1 or Table 3.1 of AS 3996.

For circular openingⁱ (CO) 250 mm, the test loads shall be the serviceability and ultimate design loads given in Table 5.1 or Table 3.1 of AS 3996 multiplied by the appropriate factor.

The Factor is the clear openingⁱⁱ area, in mm², of the top surface divided by ().

Test loads are calculated to be:
