How do you calculate unit weight of asphalt?

How do you calculate unit weight of asphalt?

Multiply Volume by the Density To determine how much asphalt you will need for the project, multiply the area’s cubic feet measurement by 148 PCF. For example, if the area is 40 cubic feet, then the formula is: 40 cubic feet x 148 PCF = 5,920 pounds of asphalt mix.

What is asphalt measured in?

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).

What is base asphalt?

Asphalt Concrete Base refers to an aggregate, sand, and asphalt cement mixture used as a base underneath more asphalt pavement courses, most commonly in a roadway application. If not hand placed, the equipment required when placing Asphalt Base will be an asphalt paving machine or road widener and 2-3 tandem rollers.

How do you find the density of asphalt?

Standard density for asphalt is 145 lb/ft3 (2322 kg/m3). Multiply the volume by the density (in the same units) to get the weight.

What is the weight of asphalt?

How much does a yard of concrete or asphalt weigh? Concrete and asphalt weights are based on the square footage and thickness of the material. On average, a cubic yard of solid concrete weighs 4,050 pounds (~2 tons), or 150 pounds per cubic foot. Solid asphalt weighs slightly less at 3,960 pounds per cubic yard.

What is the density of the asphalt?

2.243 gram per cubic centimeter

How much asphalt is in a ton?

Standard Asphalt weight Therefore 2.4 ton of asphalt = 1 cubic meter. 1 cubic yard of hot asphalt mix weighs 2.025 tons or 4050 lbs.

What is the density of hot mix asphalt?

Average Density readings to 0.1 lb/ft3 .

What is the specific gravity of asphalt?

around 1.03

How do you calculate specific gravity of asphalt?

Theoretical maximum specific gravity is determined by taking a sample of loose HMA (i.e., not compacted), weighing it and then determining its volume by calculating the volume of water it displaces (Figure 1). Theoretical maximum specific gravity is then the sample weight divided by its volume.

What is GSB in asphalt?

Gsb = bulk specific gravity of aggregate. Gb = specific gravity of asphalt. Calculation using bulk and effective gravities determined in sections 3.2.

What is GMB asphalt?

BULK SPECIFIC GRAVITY (Gmb) is a ratio of the weight of a unit volume of compacted HMA mixture to the weight of an equal volume of water, MAXIMUM THEORETICAL SPECIFIC GRAVITY (Gmm) – Ratio of the weight of a unit volume of uncompacted HMA mixture to the weight of an equal volume of water.

What is Type 3 asphalt?

IKO Asphalt Type 3 is a proven waterproofing material and is suitable for use in selected damp proofing and waterproofing applications. The product is oxidized bitumen intended for use with glass felts, modified rolls, insulation and cover boards with a slope of 0–3:12 (0-25%).

How do I calculate asphalt area?

How to Calculate Asphalt Tonnage

1. Use a tape measure to determine distances.
2. Convert the length, width and height measurements to feet by dividing by 12, since each foot contains 12 inches.
3. Multiply the length times the width times the depth to obtain the volume in cubic feet of the space to be paved.

What aggregates are used in asphalt?

Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement- ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement.

Is asphalt same as tar?

The main difference between Tar and Asphalt is that the Tar is a substance and Asphalt is a sticky, black and highly viscous liquid or semi-solid form of petroleum; bitumen variety. Tar can be produced from coal, wood, petroleum, or peat.

Is asphalt cheaper than concrete?

Lower upfront cost: Asphalt is less expensive than concrete to install. It could be about half the price per square foot to install asphalt. Although it requires more repairs than concrete, asphalt repairs are more straightforward than concrete because the cracks can blend into the original.

What are the 4 main types of aggregates?

The Different Types Of Aggregate. The categories of aggregates include gravel, sand, recycled concrete, slag, topsoil, ballast, Type 1 MOT, and geosynthetic aggregates (synthetic products commonly used in civil engineering projects used to stabilise terrain).

What is Type1 sand?

MOT Type 1 is simply a crushed limestone that has met the requirements of the Department of Transport’s specification for highway works. However, MOT Type1 is a popular product as a sub-base (hardcore) when laying patios and driveways due to its solidity.

What size is number 2 gravel?

This primarily 1″ crushed, washed gravel with a top size of 1-1/2″ is often used for drainage around perforated pipe, under concrete slabs, and as a coarse driveway topping for soft, very muddy driveways.

What is a Type 2 base?

Class II Base is a crushed and graded blend of aggregates designed to compact tightly with the proper equipment. It provides an excellent base to concrete pavers and asphalt or can be used alone as a driveway or pathway.

What are the different sizes of gravel?

In the Udden-Wentworth scale gravel is categorized into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). ISO 14688 grades gravels as fine, medium, and coarse with ranges 2 mm to 6.3 mm to 20 mm to 63 mm.

What are the different sizes of crushed stone?

Crushed Stone Grades

• Crushed stone #5 – Sizes are from 1″ down to fine particles.
• Crushed stone #67 – Sizes from 3/4″ down to fine particles.
• Crushed stone #1 – Sizes are from 2″ to 4″.
• Crushed stone #8 – Sizes from 3/8″ to 1/2″.
• Crushed stone #3 -Sizes from 1/2″ to 2″.

What size is #67 gravel?

#67 Gravel is a crushed blue-gray granite that is dry-screened to measure roughly 3/4″, meaning the actual size of any particular piece will be from 1/2″ to 1″ long. Stone dust and pea gravel are screened out, giving you an attractive landscaping material with superb drainage qualities.

What size is #57 gravel?

#57 Crushed Gravel At-A-Glance The #57 sieve produces gravel materials that are approximately 1” – 1.5” in size. To put this into perspective, you can expect gravel in this size family to be around the same size as nickels and quarters.
