What is the application rate for tack coat?
0.05 to 0.15 gal/yd2
The application rate will vary from 0.05 to 0.15 gal/yd2, depending on the condition of the old pavement surface. The pavement course surface should be evaluated to determine the amount of tack to be applied.
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).
What is the specified rate of application of bituminous emulsion tack coat on bituminous surface?
Application Rate
| Existing Pavement Condition | Application Rate * (gallons/sy) | |
|---|---|---|
| Residual | Diluted (1:1) | |
| New Asphalt | 0.03 – 0.04 | 0.10 – 0.12 |
| Oxidized Asphalt | 0.05 – 0.06 | 0.15 – 0.18 |
| Milled Surface (Asphalt) | 0.05 – 0.06 | 0.15 – 0.18 |
How do you calculate tack oil?
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 prime coat?
The prime coat shall be applied uniformly and at a rate that will provide a residual asphalt rate on the prepared surface of 0.25 lb/sq ft ± 0.01 (1.21 kg/sq m ±0.05)….Hot Mix Asphalt – Prime coat (BDE)
| Type of Surface to be Primed | Residual Asphalt Rate lb/sq ft (kg/sq m) |
|---|---|
| Fog Coat between HMA Lifts, IL-4.75 & Brick | 0.025 (0.122) |
How is tack coat applied?
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.
How is bitumen percentage calculated?
Quantity of Bitumen Calculation in Road:
- Volume of Road = 1000 x 7 x 0.075 = 525 Cum.
- Quantity of Mix Required for Road = 525 x 2400 = 1260000 Kg.
- Quantity of Mix Required for Road in Tons = 1260000 / 1000 = 1260 Tons.
- Bitumen Content = 3.4% (Taken from Bitumen Extraction Test)
What is bituminous 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.
How do you calculate bitumen?
How Much Bitumen Used in Road Construction Per Kilometre?
- Find out the dimension (Width and thickness)
- Calculate Volume of Asphalt = (Long * Width * Thickness) m^3.
- Find out the density of Asphalt (2330 or 2450 Kg/m^3)
- Calculate the quantity of Asphalt= ( Density* Volume) Kg/MTon.
What is the density of bitumen in kg m3?
Specific gravity determines the density of the bitumen. According to the ASTM D70, the density of bitumen 80/100 in kg/m3 is equal to 1009.6.
What is bituminous prime coat?
BITUMINOUS PRIME COAT. 2358.1 DESCRIPTION This work consists of treating a prepared base with bituminous material prior to placing a bituminous pavement. MATERIALS 2358.2 A Medium Curing Liquid Asphalt Provide Medium Curing Liquid Asphalt in accordance with 3151.2.
How do you calculate bituminous quantity?
Formula for Calculation of Bitumen Quantity in Road: Calculate the quantity of Asphalt= ( Density* Volume)/1000. Find out how much bitumen in the mixture (3.5-5% in Asphalt) Calculate the quantity of bitumen for Road = (Quantity of Asphalt * 3.5 %)
How is bitumen content calculated?
The bulk relative density of the material is divided by the MTD of the material from which the VIM is calculated : VIM = (1 – BRD/MTD)x100. The aggregate component of the sample from which the bitumen was extracted during the bitumen content determination is used for the particle size analysis.
