Water / ISS Volume Calculations
1. AREA TO BE STABILISED
Calculate the total area to be stabilised with ISS giving the total m2 to be
treated.
2. WATER VOLUME
ISS is applied together with the water required to bring the material to optimum moisture content. About 0.5 litre for every 1cm of depth per m2 is required but may vary according to the material’s in-situ moisture content and weather conditions.
If the material is already at or above optimum, a minimum of 1 litre / m2 of water must be used.
3. ISS VOLUME
Standard application rate for ISS is 0.03 litre per m2
The area in m2 is multiplied by the ISS application rate to give the quantity of ISS required.
Example:
Area to be stabilised - 7000 m2
ISS application rate 0.03 litre / m2
7000 m2 x 0.03 litre / m2 = 210 ISS

4. MIXING
The total amount of water required to bring the material to optimum moisture is divided
by the capacity of the water truck to estimate the total number of water loads.
It is advisable to only add the ISS to the first two-thirds of the required
water loads. Note: If optimum moisture content is obtained before the last load
should be applied, the excess load should be applied during or after
compaction. If however optimum moisture content has not been obtained after the
last load of ISS mixture has been applied, clean water without ISS must be
used.
