    The compaction of the pavement is caused by repetitive and vibratory movements of traffic and results in a depression beneath the wheel path. The shape of the depression is a clue to the layer that has densified. Compaction in a layer near the surface will produce a sharp depression compaction at a depth will cause a broader depression.

    Sep 19, 2016 calculated the compaction rate. Remember, the compaction rate, as a general rule, is about 6 mm 14 per 25 mm 1 of screed laid thickness when a vibratory screed is used and about 5 mm 15 per 25 mm 1 when a tamping and vibrating screed is used. Always verify the compaction rate of the fresh layer when building a longitudinal joint.
