Elite Lab is manufacturer and supplier in West Bengal, Bihar, Jharkhand, Kolkata, Patna and Ranchi India. Fine dust or clay-like components in fine aggregate may be quantified in a rapid field test utilising the sand equivalent test (with Sand Equivalent Test Apparatus). As a general rule of thumb, most fine aggregates include a mixture of useful coarse particles (for example, sand) and normally undesirable fine particles (such as clay or polymer dust) (ASTM 2003). Aggregate particles may be covered by these chemicals, preventing a strong connection between the asphalt binder and the aggregate. Elite lab is also exporter of Sand Equivalent Apparatus Exporter in Kolkata India.

Sand Equivalent Test Apparatus Box Consist:

• A graduated Steel rule of length 450mm.
• Four graduated fine acrylic cylinders with four rubber stoppers.
• Plastic funnel of length 100mm.
• Aspirator bottle of 5 litre with rubber cock.
• Stands for Assembly.
• Copper tube and weight foot assembly.

To remove the clay-like coatings on sand, a sample of aggregate passing through a No. 4 (4.75 mm) filter and a little amount of flocculating solution is put in a graduated cylinder and agitated. In order to suspend the clay-like material in the solution, the sample must be irrigated with more flocculation solution. Sediment times are given for both flocculated clay and the equivalent sand height, and then the sand equivalent is determined using this ratio. Sand equivalent values that are greater than or equal to one indicate a ".cleaner" aggregate.

In this case, sand serves as a substitute.

Sand Equivalent Test Apparatus Manufacturers in Bihar, Jharkhand, West Bengal, Kolkata, Ranchi, Patna, described in the Test Description section in further detail, the sand equivalent test separates an aggregate sample into two halves in order to assess the amount of plastic particles and dust. Lower sand equivalent values indicate that the soil contains more pastic and dust particles.

The stipulated minimum sand equal values for fine combined in HMA range from 26 to 60, with 45 being the most common, as per the Sand Equivalent Test Apparatus Suppliers in Bihar, Jharkhand, West Bengal, Kolkata, Ranchi, Patna. The kind of HMA layer is also a factor in determining a user's requirements (e.g., base course or surface course).
