Full Answer

What is the unit weight of construction materials?

Unit weight of construction materials is simply defined as Mass per Volume (M/V). Don’t forget the unit weight will differ based on location.

How much does a cubic metre of asphalt weigh?

Since there are a million grams in a tonne and also a million cc in a cubic metre, this value is also the density in tonnes per cubic metre. So a cubic metre of asphalt weighs 2.243 tonnes.

How do you calculate tons of asphalt per yard of paving?

It is basic arithmetic using a conversion factor of 0.057 tons of hot mix asphalt per square yard of paving per inch of depth. Measure the area to be paved, let’s say a parking area in an apartment complex with a two-way road and parking on both sides for 10 cars.

How much does a compacted concrete base weigh?

For example, the weight of poured in place concrete, with reinforcement, is only 150 lb/ft^3. There is no way that compacted base weighs more than that. You're going way off on a tangent using some inappropriate information and extrapolating it to fit.

What is the density of base course?

The maximum dry density is 2383 kg/m 3 and the optimum moisture content is 5%. A study is being conducted on full-scale pavement test sections to assess geogrid base reinforcement in flexible pavements representative of major highways.

What is the unit weight of asphalt?

142 to 148 pounds per cubic footAsphalt Mixture typically weighs from 142 to 148 pounds per cubic foot (PCF) in-place. Use 148 PCF. Calculate the tonnage needed. (remember to convert from pounds to tons; 2000 pounds per ton).

What is base course in asphalt?

The base course is the lower asphalt course (or courses), below the surface and any leveling course. The base course provides the strength of the pavement and typically has an aggregate top size of 3/4 to 1 inch. Tack / Prime Coat. The tack or prime coat is a spray applied application of emulsified asphalt.

What is the density of aggregate base?

2400-2900 kg/m3Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3).

How do you calculate asphalt weight?

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 the unit weight of aggregate?

The standard density of aggregate which is used in concrete making is about 1200-1750 kg/m3.

What material is used in base course?

The base course is generally com- posed of granular material such as crushed aggregate, gravel, selected soil, or a mix- ture of selected soil and aggregate.

What is base course made of?

Base course is a layer of the pavement structure immediately beneath the surface course. It typically consists of high quality aggregate such as crushed gravel, crushed stone, or sand that provides a uniform foundation support and an adequate working platform for construction equipment.

What is base paving?

Base Course in pavements refers to the sub-layer material of an asphalt roadway and is placed directly on top of the undisturbed soil (Sub-Grade) so as to provide a foundation to support the top layers of the pavement. It is typically made of a recipe of different sizes of aggregate rock inclusive of 1″ to fine dust.

What is the unit weight of gravel?

What is density of coarse aggregate 20mm?

How do you calculate the weight of an aggregate?

The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.

How to calculate the weight of asphalt?

When calculating the weight of asphalt by calculation, you can use a method of multiplying the volume by specific gravity. Volume is obtained by multiplying the construction area by the thickness of the pavement, but usually, the asphalt is pressed slightly because it is treated with a road roller etc. after spreading.

How thick is a ton of asphalt?

The density of asphalt is generally given at 140 lbs per cubic foot (I have assumed you would like this in imperial as you use feet) At that density a ton ( 2240 lbs) is 16 cubic feet so it now comes down to how thick you want the coating, at 1 inch thick the ton will cover 12 x 16 (192) square feet.

How many cubic yards of asphalt is 5000 cubic feet?

Asphalt is generally paid for in cubic yards or tons. 5000 cubic feet is 185.2 cubic yards (multiply times 1 cubic yard per 27 cubic feet). In order to compute tons, you will need to know the density of the asphalt. It will vary based on the mix design.

What is the specific gravity of asphalt?

In general, asphalt used for paving is called “dense particle size asphalt mixture”. Although the specific gravity is set to 2.35, the specific gravity determined by the manufacturing company may differ depending on the product asphalt actually used for construction.

How much does 1000 kg of water weigh?

If you are asking for cubic meter that would make 25 tons, then, here it is. 1 kg of water is equal to 1 L or 0.001 cu meter. 1000 Kg is equal to 1 ton of water or 1 cubic meter of water. 25 cubic meters will weigh 25 tons.

What does "**" mean in asphalt?

The "**" means "to the power of", so for "filet" above, you have "length to the power of 2", or "length squared". The unit weight of asphalt is going to vary depending on the density, but most numbers I've seen run between 140 and 147. Your provider will be able to provide you with an exact unit weight.

How much bitumen is oxidized?

For oxidized bitumen, it may vary from 1.00 to 1.07 g/cm3, depending on the severity of oxidation. For polymer modified bitumen, it may vary from 0.98 to 1.05 g/cm3, depending on the polymer and concentration used, and if it’s crosslinked or not. For crum-rubber modified bitumen, it can go up to 1.07 g/cm3.
