How do I calculate the price per unit mass of asphalt?

I can therefore calculate the price per unit mass using the formula: $$Price\,per\,unit\,mass = {Total\,cost\,of\,asphalt \over Weight\,of\,asphalt} = {$2160 \over 18\,t } = 120\,$/t$$ At this point, I am now able to enter the values into the asphalt volume calculator.

How much does it cost to have asphalt delivered?

Asphalt delivery costs $40 to $80 per hour or $4 to $9 per ton within 15 to 20 miles of asphalt plants. Greater distances cost more because hot-mix asphalt must stay at precise temperatures for immediate paving on delivery. Asphalt delivery is typically part of material costs in project estimates.

What is the theoretical quantity of emulsified asphalt?

Atheoretical = theoretical quantity of emulsified asphalt, (A/R). R = percent residual asphalt in the emulsion expressed as a decimal. Check with supplier to determine percent residual asphalt content of emulsion. K = 0.90 for winter construction.

What are the methods of measurement for asphalt?

Types and methods of measurement. Tack coat (emulsified asphalt) will be measured in square yards (SY) and converted to gallons (GAL). Asphalt paving will be measured in square yards (SY) and, with the corresponding depth in inches (IN), converted to tons (TN).

How much does a 50 lb bag of asphalt cost?

A 50 lb. bag of cold-patch asphalt costs $8 to $20 and covers 5 to 7 square feet at a 1" depth. Cold-patch asphalt is the only DIY-friendly option that cures by compaction alone.

How much does asphalt cost per ton?

Asphalt cost per ton. Asphalt costs $40 to $80 per ton on average. Asphalt prices vary depending on the mix and material ingredients. One ton of asphalt covers 30 to 80 square feet. A 2-car driveway needs 7.5 to 18 tons of asphalt, depending on the thickness. Asphalt cost per ton by material - chart.

How much does it cost to rent an asphalt paving machine?

Renting an asphalt paving machine costs $750 to $3,600 per day on average. Asphalt roller rental costs $120 to $700 per day for ride-on compactors 3 to 4-foot wide. Renting asphalt paving machinery sometimes requires a commercial driver’s license and additional training.

How many tons of asphalt is in a cubic yard?

There are typically 2 tons in 1 cubic yard, depending on the mixture's density. A cubic yard covers 65 to 110 square feet with an asphalt layer 3 to 5 inches deep.

How much does it cost to haul asphalt?

A bulk truckload of asphalt costs $500 to $1,800, including delivery fees. Tandem trucks carry 13 to 20 tons of asphalt that cover 550 to 850 square feet with a layer 3 to 5 inches thick. Prices vary according to the asphalt-delivery distance.

What is the difference between asphalt and blacktop?

The terms “asphalt” and “blacktop” are slightly different. Highway pavers use asphalt, which contains less stone than real blacktop. Blacktops are used for residential areas with less traffic, are easier to repair, and more durable than asphalt.

Asphalt calculator formula

Based on the measurements you provide for required length, width and thickness, the calculator first works out the area and volume of the hot asphalt mix required using the below formulas:

Calculation examples

Imagine I want to pave over an area measuring 20 feet by 4 feet to a thickness of 6 inches using standard asphalt (140 lb/ft³) and costing $150 per US short ton.

What if my measurements are in different units?

The best thing about our asphalt calculator is that it takes care of this for you.

What is hot mix asphalt?

Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together.

What is asphalt binder?

Asphalt binder is a petroleum derivative, though additional materials are often added to modify the properties of the binder. Pike also produces specialty products like Warm Mix Asphalt (WMA) pavement and Porous Pavement.

Introduction: What is Asphalt?

Asphalt is a black, sticky, and highly viscous liquid or semi-solid form of petroleum. It is used primarily in road construction and roofing. How to Calculate the Quantity of Dump Trucks in Asphalt

Asphalt vs Bitumen

Asphalt is a mixture of sand, aggregates, and bitumen. In asphalt, bitumen is used as a binder to hold together the asphalt, which are then heated to high temperatures so that they can be laid down on roads or other surfaces.

What are the Types of Asphalt?

Hot Mix Asphalt (HMA): Generally hot asphalt mixes are produced at a temperature between 150 to 180 0C. Different asphalt mixtures can be used on the basis of the usage and their application area. It is mostly used for paving and patching. It is easier to work with asphalts when their temperature is high.

General

The design method described in this section is based on a modification of the original Kearby method and was first recommended to TxDOT by Texas Transportation Institute in 1981 (Epps et al., 1981). It is still the method most commonly used by TxDOT today.

Laboratory Tests

This design methodology requires the knowledge of some physical characteristics of the aggregate, such as unit weight, bulk specific gravity, and the quantity of aggregate needed to cover one square yard of roadway.

Determining Design Rates

Aggregate Spread Rate. The Board Test is used to find the quantity of aggregate on a board of known aggregate such that full coverage, one stone in depth, is obtained. A one-half square yard area is a convenient laboratory size. The weight of aggregate applied in this area is obtained and converted to units of pounds per square yard.

Types and Methods of Measurement

  1. Tack coat (emulsified asphalt) will be measured in square yards (SY) and converted to gallons (GAL).
  2. Asphalt paving will be measured in square yards (SY) and, with the corresponding depth in inches (IN), converted to tons (TN).
  3. Pavement marking will quoted by others and represented by the lump sum (LS).

Project Specific Factors in Take-Off and Pricing

  • Some factors vary from project to project and are detailed in the plans and specifications, arising from sources such as: Project size and constructability:Economies of scale. The project may call for a product or method not economically procured or performed. Schedule:The schedule, as it relates to duration, acceleration, season, time of day, and potential for escalation, needs to be ac…

Overview of Labor, Material, Equipment, Indirect Costs and Approach to Mark-Ups

  • Internal material costswill depend on the transfer price (price negotiated within the contractor’s company), typically on a project-by-project basis. The estimator must ensure accurate quantities and account for waste in applying the per ton rate to the estimate quantities. External costsare those quoted by suppliers. In both cases the estimator is responsible for ensuring that the mater…

Special Risk Considerations

  1. Is the contractor bidding as Prime/General Contractor, quoting another contractor on the project, or both?
  2. Consider the unit type (tons of asphalt placed versus square yardage of area paved) when working on a pay item basis, and which items are included.
  3. Which items may be considered incidental?

Ratios and Analysis – Testing The Bid

  • After all take-off, pricing, application of in-directs and mark-ups, and other relevant considerations, the estimate should be reviewed for mathematical accuracy, and tested against benchmarks.
