EXAMPLE 2.6 Determination of Aggregate Requirement for a Roadway Aggregates from a gravel pit are required for constructing a road embankment. The porosity of the aggregates at the gravel pit is 60%. The desired porosity of the compacted aggregates in the embank- ment is 25%. For a section of the embankment 7.5m wide x 0.6m compacted thickness x 1 km long, (a) calculate the volume of aggregates required. (b) Just before the construction of the embank- ment, a re-check of the porosity of the aggregates at the gravel pit was conducted. The porosity was 65% rather than 60% (an error of +8.3%), what extra percentage of aggregates would be required to construct the embankment. Assume a swell factor of 1.
