how to calculate the rate of spray of prime coat in road construction. - 1 ... Tray Test is used to calculate the rate of spread of prime or tack coat. The test uses a 20cm X 20 cm X 3 cm tray placed on the surface to be primed at some intervals in the path of the sprayer/emulsion distributor. They are placed between the wheel's path/tracks.

This calculation is based on a ratio of two-thirds residual asphalt binder and one-third water in the asphalt emulsion and is done by multiplying the residual asphalt content by a factor of 1.5 to determine the required application rate (as discussed in "How a Tack Coat Improves Your Paving," in the May issue of Pavement Maintenance ...

The tonnage calculation is specific to Asphalt only. 1. How to measure the pavement? To determine the amount of asphalt you will need for a paving job you first need to know the area to be paved. This may be simple if the area to be paved is square, rectangular …
Record as Spray Width (line "H"). 12. Calculate the distributor speed and spread rate as directed in steps 2 to 6 of Section 3.1.1. 4.0 HINTS AND PRECAUTIONS 1. Make sure that the distributor tank is level when measuring quantities. 2. The temperature and viscosity of the asphalt will have a major effect on the spray rate at a given setting.
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 design application rate." Sect. 310.03

The oil lobby is lying. Canadian oil isn't clean oil. The oil and gas industry is putting great efforts into trying to convince the Canadian public that they are making strides to be more environmentally responsible. Don't buy it. The fact is oil and gas companies' total impact on Canada's water, land, species, and the climate continues ...

Guide to Pavement Technology Part 4K: Selection and Design of Sprayed Sealsis a guide to the procedures for the selection and design of sprayed seals. This is an update of previous Austroads procedures based on the philosophy of filling up voids in the aggregate matrix with binder, to a depth of about one half to two thirds the height of the aggregate when laying on its least dimension.
Asphalt, or bitumen, is a sticky, black and highly viscous liquid or semi-solid, composed almost entirely of petroleum. It is present in most crude petroleums and in some natural deposits. It is the material which made the La Brea tar pits.. Its main use is in road construction. Mixed with "aggregate" (sand, gravel, crushed stone, etc.) it makes a good road surface.
Answer (1 of 8): It cannot be said with this much of information. Bitumen is provided in road construction in various forms like BM (Bituminous Macadam), DBM (Dense Bituminious Macadam), BC (Bituminous Concrete), SDBC (Semi Dense Bituminous Concrete), Bituminious emulsions (Prime Coat/Tack Coat)....

The rate shall be adjusted up or down so that no bleed through occurs during rolling. Pneumatic tire rolling shall follow immediately after the screenings is applied. The following equipment to be used for the chip seal shall be as follows: A. An asphalt distributor for application of the emulsion shall have a full circulation spray bar that is
Use caution when the tack coat spray rate is above 0.15 gallons per square yard because of the possibility for tack coat puddling and tack coat runoff. Note 3. As spray rates are "minimum", they are rounded up to the nearest 0.01 gallon per square yard. Calculated rates are based on volume at 60 degrees Fahrenheit and 57% binder residue.
100 mm centres, the spray bar output is therefore 180 L/min per metre width of bar. By maintaining a constant spray jet output, the rate of application of binder is directly proportional to the forward speed of the sprayer. Some bitumen sprayers provide an interlock between forward speed and spray pump output to vary output in proportion to ...

seal surface texture, chip ALD and application rates, enabled the production of a spray rate chart. This, in turn, led to the Transit New Zealand Design Algorithm known as RD286 (NRB 1971): R = (0.138 ALD + e) T f RD 286 where: R = residual binder application rate ( …

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.

If set correctly, the spray evaporates evenly but remember to raise the boom if the round is not the target. Calibration To apply a specifi ed rate of chemical to the target surface (e.g. plant, soil, pest), you need to measure the total spray output of the machine, the travel speed and the swath width. Then calculate the application rate.
Use any of the calculators by inputting the known figures you have, from your sprayer calibration or Nozzle information charts, for example, and the calculator will work out what settings need to be changed or adjusted to give you the required output for accurate application. You can change or adjust any of the figures at any stage and ...
apply this to calculate the hot mixture application rate (line 24). Check the pump speed and road speed appropriate to the required rate of application of hot cutback bitumen by reference to the Spraying Table which is kept in the sprayer cabin. Record these in lines 25 and 26.
