What is the density of asphalt pavement?

What is the density of asphalt pavement?

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 pavement density?

Density is the unit weight of a mixture. Density is usually shown as a percent of maximum theoretical (Gmm) or the specific gravity of the in-place compacted density divided by the Gmm. The normal target in-place density on a “dense” hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids).

What is the compaction rate of asphalt?

Remember, the compaction rate, as a general rule, is about 6 mm (1/4″) per 25 mm (1″) of screed laid thickness when a vibratory screed is used and about 5 mm (1/5″) per 25 mm (1″) when a tamping and vibrating screed is used.

What is asphalt compaction?

For asphalt mixtures, compaction locks the asphalt-coated aggregate particles together to achieve stability and provide resistance to deformation (or rutting) while simultaneously reducing the permeability of the mixture and improving its durability.

What is compacted asphalt?

Compaction is the process of reducing the volume of material by compression. In asphalt paving, this is achieved by. the types of rollers, number of rollers, the rolling patterns, and the material placement temperatures.

Why is asphalt density important?

Density is one of the most important parameters in construction of asphalt mixtures. A mixture that is properly designed and compacted will contain enough air voids to prevent rutting due to plastic flow but low enough air voids to prevent permeability of air and water.

What is the asphalt paving coverage per ton?

On average, one ton of asphalt can cover between 80 to 100sq feet. This is based on types of asphalt such as HL3 , HL3A and HL2, which are the kinds of asphalt used on ordinary driveways. Of course, the thickness of the asphalt you lay will determine how much land you can cover with one ton.

What are asphalt paving specifications?

The majority of cities require this part to be four inches thick, while some may require it to be six inches . The top layer is the asphalt and should be two inches at a minimum. As an expert team of paving contractors, you can rest assured that we know the requirements of each city or town in York and Adams County.

What is the unit weight of asphalt?

Concrete, Asphalt weigh(s) 2.243 gram per (cubic centimeter) or 1.297 ounce per(cubic inch). See this and other substances density in 285 measurement units.

What is pavement made of?

Modern flexible pavements contain sand and gravel or crushed stone compacted with a binder of bituminous material, such as asphalt, tar, or asphaltic oil. Such a pavement has enough plasticity to absorb shock. Rigid pavements are made of concrete, composed of coarse and fine aggregate and portland cement,…
