In addition to material strength (Xuan et al., 2015;Li et al., 2017), the crushing characteristics of the aggregates are essential to ensure road stability.
The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod of circular cross-section 16mm diameter and 45 to 60
The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = (Weight B / Weight A) × 100. Where: Weight A is the weight of the surface-dry sample. Weight B is the weight of the fraction passing the appropriate ...
Result: Aggregate crushing value = 20%. Result Analysis: The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like runways and …
