aggregate crushing value experimen

AggregateAbrasionValuePolishing Stone. Introduction In 1950 increased traffic flows and higher speeds on trunk roads, together with concerns about road safety led to research into the relationship between road materials and skid-resistance. Research at the UK Road Research Laboratory showed a significant relationship between polishing of aggregates used in road surfaces and skid resistance.

  • Aggregate Crushing Value Test Determine Aggregate

    Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place.Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve.W1-W =Weight of surface dry sample.
