Determine Spray Rate: The spray rate is the rate at which the coating solution is sprayed onto the tablets. It is typically expressed in mL/min and can be calculated using the following formula: Spray Rate (mL/min) = Weight of Solids (g) / Coating Time (minutes) The spray rate calculations can also be performed by the …

Bitumen Calculator is Road Construction Calculator Which is Calculate the Quantity of Bitumen With using Length Breadth and Rate of Spary.
Bitumen emulsion has a vital role towards construction, rehabilitation and maintenance of roads. Emulsions used for road work are cationic slow setting ... Rate of Spray as per MORTH(5th Revision): Type of Surface: Rate of Spray (kg/sq.m) WMM/WBM: 0.7–1.0: Mechanically lime/cement stabilized soil bases, lime cement bases: 0.9–1.2:
Bitumen Tack Coat Calculation ... Rate of Spray of Binder in Kg per sq. m: Bituminous surfaces: 0.20 – 0.30: Granular surfaces treated with primer: 0.25 – 0.30: Cement concrete pavement: 0.30 – 0.35 . Area for Bitumen = Length × Breadth . Total Quantity = Total Area × Rate of Spray .
the Engineer prior to initial asphalt plant mix placement to demonstrate an even and accurate spray application. Calibration will be considered acceptable when the spray rate is uniform and within 0.02 gallon per square yard of …
The spray rate for bitumen is determined jointly from the measured voids between chips, the nature and intensity of traffic and the texture of the existing road surface. A …
A well-presented bitumen driveway can make a real difference to the visual approach to your home, increasing its value and lowering your driveway maintenance. A bitumen spray seal is a two coat system. Liquid bitumen is sprayed onto a prepared road base surface. A 10mm aggregate is spread in a uniform layer and rolled.
Bitumen sprayers must be able to spray any design rate of application required within the range shown below inclusive, up to the maximum effective width of spray for which the sprayer has been ...
The application rate for prime will be specified by the client or his agent based on the condition of the road surface, but will generally be 0.7 L/m 2 for MC30 and 0.6 L/m for MC70 with the net quantity of bitumen residue in the region of 0.35 L/m 2. • For open graded or coarse layers, the spray rate can be increased by 0.15 L/m 2.
A fog spray is a light application of diluted bitumen emulsion that is applied as a maintenance procedure on an existing bituminous surfacing to assist in retaining the aggregates in place, sealing the layer against water ingress or to "rejuvenate" the surfacing when it is showing signs of "dryness" resulting from ageing/hardening of the bitumen.
The asphalt tack is used to bond layers of asphalt mixture together, prevent slippage, and obtain long service life of the new pavement. 5. APPARATUS . 5.1 Calculator . 6. TEST SPECIMEN . 6.1 None . 7. PROCEDURE . 7.1 The roadway must be measured first to determine the proper area for calculating tack rate.
