6.2.1 Basic Binder Application Rate (Bb)
The procedure for the determination of the basic binder application rate, Bb (L/m2), for the proposed seal is as follows:
- Determine the design voids factor, VF as described above.
- Determine the basic binder application rate, Bb, to the nearest 0.01 L/m2 by multiplying the VF by the ALD, as shown in Equation 6:
| Bb = VF x ALD (L/m²) | 6 | |||
| where | ||||
| VF | = | design voids factor | ||
| ALD | = | average least dimension of aggregate |
For example: VF = 0.16 L/m2/mm and ALD = 5.8 mm
Bb = 0.16 x 5.8 = 0.928 = 0.93 L/m².
