density of loose asphalt wearing course is 2.20ton/CM-2.450ton/CM
What else can I help you with?
Is there a difference of densities of asphalt wearing and binder course?
Yes, there is a difference in densities between asphalt wearing and binder courses. The wearing course, which is the top layer, typically has a lower density due to the use of smaller aggregate sizes and higher air void content, designed to provide better skid resistance and surface drainage. Conversely, the binder course, situated beneath the wearing course, has a higher density as it uses larger aggregates and is designed to provide structural support and load distribution. This difference in density helps optimize the performance of each layer in an asphalt pavement system.
Please Convert 509 tons of asphalt concrete binder course to cubic meter?
To convert 509 tons of asphalt concrete binder course to cubic meters, you need to know the density of the material. The density of asphalt concrete binder course can vary, but a common value is around 2.2 tons per cubic meter. Using this value, 509 tons would be approximately 231.36 cubic meters.
What is the problem if use the wearing course in the place of binder course?
Asphalt binder course is an intermediate course between a base course and an asphalt surface course. The binder course is usually a coarse-graded aggregate Asphalt Concrete containing little or no mineral matter passing through a No. 200 sieve. The surface course is one or more layers of a pavement structure designed to accommodate the traffic load, the top layer of which resists skidding, traffic abrasion, and the disintegrating effects of climate. The top layer is sometimes called the wearing course. This course is very fine in gradient compared to binder.
What is the top layer of a road?
The top layer of a road is called the wearing course or wearing surface. It is the visible layer of the road that provides friction for vehicles and protects the underlying layers from wear and tear. The wearing course is typically made of asphalt or concrete.
What has the author J H Denning written?
J. H. Denning has written: 'Assessment of 'Novophalt' as a binder for rolled asphalt wearing course'
What is one advantage of using asphalt and one advantage of using concrete as the wearing course of a road?
One advantage of using asphalt as the wearing course of a road is its flexibility, which allows it to better withstand temperature fluctuations and heavy loads without cracking. In contrast, one advantage of using concrete is its durability and longevity, as it can last longer than asphalt under similar conditions and typically requires less maintenance over time.
How much is the value of compaction of asphalt base course?
The value of compaction for an asphalt base course is typically targeted at 95-98% compaction density. This level of compaction ensures that the base course is strong, durable, and able to support the weight of the overlaying asphalt layers and traffic loads. Achieving the specified compaction value is critical for the long-term performance of the pavement structure.
What is the density of binder course?
The density of the binder course in asphalt pavement typically ranges from about 2,200 to 2,500 kg/m³ (or 140 to 156 lb/ft³). This density can vary based on the specific materials used, the mix design, and the compaction achieved during installation. Proper compaction is crucial to achieving the desired density and performance characteristics of the binder course.
What is the density of asphalt pavement?
density of loose Asphalt is 2.20Ton/CM-2.45Ton/CM
How do you convert 45 square meters of asphalt to tons?
The answer requires the average thickness and density of the asphalt.
Why do you do leveling course in asphalt?
The leveling course in Asphalt paving is used to eliminate irregularities in an existing condition to further superimpose the new paving.
Will Asphalt sink or float in sea water?
Asphalt, being denser than water, will sink when placed in sea water. This is because the density of asphalt is about 1.36 g/cm³, while sea water has a density of around 1.025 g/cm³.
