There is good agreement in the literature on application rates. The Asphalt Institute recommends application rates of 0.9 to 2.3 L/m2 (0.2 to 0.5 gal/yd2) for MC cutbacks and 0.5 to 1.4 L/m2 per ...
In this technique bitumen spray-rates are varied across the lane width to account for the impact of traffic in the wheel-paths. This leads to designs where higher binder application rates are used on the shoulders and between the wheel-paths and lower rates in the wheel-paths.
SprayWare is a collection of tools and resources designed specifically to assist you with nozzle selection and spray system optimization. Flow Rate Calculator: Use this calculator to determine the flow rate of any nozzle at any operating pressure.Inputs to this calculator are the nozzle type, current operating pressure and flow, desired flow or desired pressure.

· asphalt binder because of the higher residual rate required for RS1 and RS2. Rapid-setting emulsion PMCRS2 may cause "spider-webbing" when number 1 nozzles are used with
Asphalt Emulsions –A History • First developed in the early 1900s • Early use in spray applications + dust palliatives • Growth use relatively slow: • Limited by the type of available emulsions • General lack of knowledge • Steady rise in volume since the 1970's Why Use Asphalt Emulsions? • No petroleum solvent required to liquefy
Asphalt Emulsion Calculator To use the Asphalt Emulsion calculator, enter the length of the road, the width of the road, and the specified spray rate (usually determined by your respective Department of Transportation). The calculator will provide an estimate in gallons of …
Surface Dressing with AC Quantity and spray rate of bitumen is calculated later. Assumed that 50% void present immediately after spreading the Single size aggregates When compacted, particles reoriented and voids drop to 30%. 32
Multiply the weight density of the asphalt by the volume to arrive at the weight of the asphalt needed in pounds. Consult the asphalt manufacturers if you do not know the weight density of the asphalt. In the example, use a typical weight density of 145 pounds per cubic foot.
300-3 Equipment. 300-3.1 Pressure Distributor: Provide a pressure distributor that is equipped with pneumatic tires having a sufficient width of rubber in contact with the road surface to avoid breaking the bond or forming a rut in the surface.

Typically, for a nominal 14mm aggregate will require a spray rate in the order of 0.8 to 1.0 litres per square metre. The spray rate will depend on the average least dimension ((ALS) of the aggregate so that the aggregate isn't drowned in the bitumen.
Before Sealcoating After Sealcoating. Sealcoatings is a true "Barrier coat" between asphalt surfaces and the destructive elements. The term "sealcoating" means keeping the redeeming properties of asphalt sealed in to prolong the pavement life and preserve its functional properties.
The other alternative is to dilute or thin them down and then the liquid coal tar or bitumen is applied by brush or by dipping. Then the calculation should be modified by calculating the amount of thinner added.

The flow rate calculator helps to determine the flow rate of any spray nozzle at any given operating pressure. Need additional help, talk to one of our experts. Flow rate calculator from Spraying Systems Co.
Determining chemical rates for dilute and concentrate spraying Chemical label directions provide a 'rate per 100 litres'. The water volume needed to spray a vine canopy to the 'point of runoff' is the dilute volume and is required to calculate how much chemical to use. Setting the amount of product that must be applied to a particular
Also from Fig. 5 the modified tack coat asphalt emulsion (tack coat asphalt emulsion with 1.5% Latex emulsion) has a higher shear strength value compared with the unmodified tack coat asphalt emulsion at an applied rate of 0.25 l/m 2 at two different temperatures 25 and 60 °C.
Find the volume of asphalt using the tank gauge readings. Find the standard asphalt volume using relation. From the table "Volumetric correction factor for asphalt", for the correction factor is 0.9523. Substitute 2000 gal for volume and 0.9523 for volume correction factor
Spray and chip is a surfacing technique involving the spraying of hot bitumen or emulsion over an existing old surface or a prepared base, followed by rolling in a thin single layer of washed stone chippings to provide surface texture, to prolong the road life, and also provide skid resistance.
