Rate Of Spread Manufacturer,Supplier and Exporter in India
Product Code : TVT-BATE-10355
The Rate Of Spread tray apparatus from Tvet Equipments is a simple, field-portable device used to determine the rate of spread of bituminous binder sprayed onto a road surface during surfacing or surface-dressing work.
How It Works
A metal 300 mm square tray of known weight is placed on the sprayed surface directly in the path of the binder distributor and lifted afterward by four attached chains onto a balance. The weight of binder collected on the tray is read off the balance and, knowing the tray's area, converted to a rate of spread in kg per square metre, giving a quick field check of distributor output.

Frequently Asked Questions
Q1. How is the rate of spread calculated from a tray reading?
The weight of binder collected on the known 300 mm x 300 mm tray area is divided by the tray's area to give the rate of spread in kg per square metre.
Q2. How accurate is the reading?
The associated balance offers a readability of 0.5 kg/m², sufficient for field verification of distributor spray rates.
Q3. Is this apparatus used in the field or the lab?
It is a field instrument, used directly on the road surface during or immediately after binder spraying, rather than in a laboratory setting.
