How many square feet does a gallon of tack coat cover?
FILING SYSTEMS • For Use As A Tack Coat For Patching Or Paving: One gallon of SS-1H Asphalt Binder will cover approximately 180-260 square feet (20-29 square yards) when diluted properly (1 part SS-IH Asphalt Binder, 1 part water).
How do you calculate an asphalt tack coat?
Therefore, the estimated quantity of tack coat is determined as follows: Quantity of Tack Coat = (quantity of emulsion in gallons) ÷ (gallons of emulsion per ton) = 61,952 gallons ÷ 240 gal./ton = 258.1 tons Quantity of Tack Coat = 259 tons.
What is the rate of spraying of bitumen in tack coat?
Spray Bar Nozzle Size If a 1:1 diluted asphalt emulsion is used and the application rate is 0.18 gal. /sq. yd. (for a residual amount of 0.06 gal. /sq. yd.), it will generally be necessary to use larger nozzles on the spray bar to achieve the desired tack coat uniformity.
What is difference between tack coat and prime coat?
A prime coat is an application of an asphalt cutback or emulsified asphalt to a prepared base. Tack is an adhesive for gluing two asphalt layers together. A subgrade or rock base is not a single component.
What is a tack coat for pavement?
Tack coat is a sprayed application of an asphalt binder upon an existing asphalt or Portland cement concrete pavement prior to an overlay, or between layers of new asphalt concrete.
What is diluted tack coat?
A tack coat is a very light spray application of diluted asphalt emulsion. It is used to ensure a bond between a surface being paved and the new course.
How hot should tack be?
The tack coat material in the distributor tank must be kept at the proper temperature to assure that the material can be sprayed uniformly onto the existing pavement surface. When an asphalt emulsion is used, it should normally be applied at a temperature between 120oF and 160oF.
What is the purpose of a tack coat?
Tack coat is a thin layer of asphalt that ensures the bonding between old and new asphalt layers. It is also used in construction or for renovation of roads to achieve better strength. Tack coat is sticky, which is very important for forming a secure bond between the two layers of asphalt.
