The findings of this section are based on data from a pavement construction project that has been recently
completed in the Middle East. During construction, samples from a total of 18 batches corresponding to 18 paving
days were collected for testing and QA/QC analysis. Each batch is in the order of thousands of m3/day. Due to the
high stakes of this project, and for the interest in more reliable and accurate QA/QC, and hence expected
performance, the stakeholders agreed on conducting the SPT test for each batch in addition to the commonly
adopted volumetric tests.
