What is Asphalt Pavement?
Asphalt pavement is the assemblage of liquid asphalt along with stones, sand, and additives. The liquid asphalt is a black-colored sticky substance that acts as the binding agent in asphalt pavement.
Moreover, asphalt is water repellent in nature that protects the underneath surface of the pavement from the fierce enemy, water.
What is the Processing Method of Asphalt Pavement?
Various methods are involved in processing a fine asphalt pavement, including predose, drying, and transfer of aggregates to the mixer.
The belt weighing instrument weighs all the aggregate components of the asphalt pavement, followed by the advancement to the second step.
During the second step, the weighted components allow drying at 300o C in a rotary drying drum. Later, the belt weighing instrument again weighs the dried components, subsequently sifted and stored into silos.
3.Transfer of Aggregates to the Mixer
A heated tank keeps the liquid asphalt separate to which the stored components are added. The paving material forms the liquid asphalt, and components are mix together afterward.
In asphalt plants, the hot tankers keep the resulting mixture separate until it is ready for moving to the required site.
Moreover, dump trucks transport the fresh asphalt mixture while maintaining its optimum temperature.
Surface Preparation Before Asphalt Paving
Surface preparation is a key factor that directly influences the quality of asphalt paving. A well-prepared underneath surface improves the applicability duration of the asphalt paved surface.
Firstly, it is important to lay a thin layer of liquid asphalt that acts as a binder between the surface underneath and the asphalt pavement.
Afterward, an asphalt paver lays a layer of the hot asphalt mixture on the ground, followed by the compression of that layer with an asphalt roller.
The compressed asphalt mix solidifies soon after cooling down for 24 hours or more.
The quality of the asphalt mixer and the extent of compression highly affect the traits of the asphalt paved surface.
What Type of Equipment is Useful for Asphalt Paving?
Asphalt paving requires a specific kind of equipment for its proper processing. These equipment include:
Milling machines remove the upper surface of the pavement while resulting in a rough surface that needs to be repaved.
Flatliners help smooth the surface by breaking down the bumps on the upper surface.
A stabilizer uses its blade to grind the old pavement. Moreover, the stabilizer can mix the material into a sub-base to make it strong.
Asphalt pavers set the asphalt layer on the surface, and screed, a part of the asphalt paver, compresses the laid layer.
Graders with large blades grind the dirt/gravel base and give rise to a flat surface. Graders also create a gravel-based path for water drainage.
Rollers move on the surface and compress the laid asphalt layer.
Drones help with the mapping of the topography of the work site for better project management.
After milling or grading, sweepers clean all waste from the job site to avoid debris accumulation in asphalt paving.
What are the Main Types of Asphalt Mix?
The diverse need for asphalt paving in commercial and residential localities requires numerous types of asphalt, based on the necessity of the situation.
Different types of asphalt mixes are easily producible by changing the number of its raw components. However, these types of asphalt generally classify under four basic categories, which are as follows:
1.Hot Mix Asphalt
One of the most commonly used categories of asphalt mix is hot mix asphalt. As the name represents, it is a type of asphalt mix that lays on the ground while keeping its temperature high between 300 to 350o F.
Hot mix asphalt further divides into three subcategories:
Dense Graded Mix Asphalt
Stone Matrix Asphalt
Open Graded Mix Asphalt
The Dense graded mix asphalt advances into two subdivisions based on the number of aggregate components, i.e., fine-graded mix asphalt and coarse-graded mix asphalt.
The fine-graded mix asphalt consists of higher quantities of sand and small stones, unlike the coarse-graded mix asphalt. This feature makes it suitable to pave roads for heavy traffic, such as highways.
Contrarily, the coarse-graded mix asphalt acts as a binder or base to reinforce the fine-graded mix asphalt to raise roads, driveways, or parking lot surfaces.
2.Warm Mix Asphalt
Warm mix asphalt is the second type of asphalt mix that requires lower temperature (200-250o F) for its manufacturing process.
Moreover, warm mix asphalt production needs less fossil fuel supply that makes it cost-effective. However, this asphalt mix requires more binding material to pour and spread on the surface at low temperatures.
3.Cold Mix Asphalt
Another type of asphalt mix is cold mix asphalt that is easily producible at any temperature through a simple manufacturing process.
Cold mix asphalt can repel water as well as it stays soft in a cool atmosphere. These attributes make it fit for pothole repairs.
4.Porous Mix Asphalt
As the term suggests, porous mixed asphalt contains asphalt material with small pores. These small pores allow the porous mixed asphalt to work better to manage stormwater through eco-friendly methods.
The stormwater moves down the paved surface, followed by the natural water cleaning processes.
Due to its eco-friendly treatment of stormwater, EPA encourages constructors to use porous mix asphalt for their projects.
What are the Perks of Using Asphalt?
Asphalt is an eco-friendly material that provides strength to paved surfaces. If laid properly, asphalt paving has its perks over other materials for constructing pavements.
Some of the prominent benefits of using asphalt paving are as follows:
1.Asphalt Paving is Eco-friendly
Do you know that according to the National Asphalt Pavement Association, the asphalt industry recycles asphalt at a rate of 99%? This makes asphalt a perfectly recyclable material and an eco-friendly option for building pavements.
Recycling asphalt promotes no-waste production as the process involves recycling old tires, shingles, and other metal castings.
Besides, the recycled asphalt mix is stronger than the freshly produced asphalt mix and provides greater strength to the paved surface. Additionally, the recycled asphalt mix improves the asphalt life cycle and its resistance against rut.
2.Asphalt is Durable and Lasts a Long Time
Asphalt is a strong and sturdy construction material with a long lifespan. The conventional layering of the asphalt mix on the prepared surface and its proper maintenance can enhance the life cycle of asphalt paving for more than 20 years.
3.Asphalt Paving Saves You a Good Fortune
Asphalt paving can save you a good fortune as compared to other paving methods like concrete paving.
Asphalt exists as one of the forms of petroleum that are obtained from natural deposits. Natural petroleum can be refined to obtain asphalt, which is cost-efficient and easily available in the market.
Consequently, asphalt paving is a budget-friendly method for pavement.
4.Asphalt Paving Consumes Less Time
Asphalt mix comprises basic components that are easily accessible from the market. Besides, the basic components require less effort and time to convert into asphalt mix through simple mixing processes.
5.Asphalt Paved Surface Reduce Traffic Noise
Heavy traffic brings a bulk of noise along with it. A convenient way to reduce this noise is to use asphalt mix for paving the surfaces, varying from highways to driveways.
The open-graded and fine-graded surfaces of the asphalt mix work simultaneously to absorb the traffic noise.
Asphalt paved surfaces can lower traffic noise by 3-5 decibels than surfaces with noise walls.
6.Asphalt Provides Natural Water Drainage System
Generally, all asphalt mix types can withdraw water from the asphalt paved surface, but the porous mix asphalt is superior for this purpose.
Porous mixed asphalt directs the water to move underground through a specific route, where it naturally filters the water.
7.Asphalt Paving is a Safe Option
Do you know that 90% of the total paved roads in the U.S are asphalt paved? Asphalt paving is the best suitable option for paving surfaces.
It is safe to use and comes in handy in various situations. Due to its ability to manage water and resist skid, asphalt paving is a go-to option for paving.
Moreover, dark-colored asphalt melts the ice efficiently and makes the paved roads safer for vehicles.
How Can Asphalt be Damaged?
Without proper installation processing and regular maintenance, asphalt is also at risk of getting damaged.
Asphalt damages might include:
Various kinds of cracks can deface the asphalt paving based on the cause of damage.
Cause: Poor longitudinal joint construction
Result: Parallel to the centerline of the pavement
Cause: Complications in the underlying layer
Result: Perpendicular to the centerline of the pavement
Cause: Heavy vegetation or lack of support at the edge of pavement
Result: At the edge of the pavement
Cause: Weak asphalt mix or the weak bond between pavement layers
Result: Stretch marks all over the pavement
Cause: Use of dry asphalt mix that follows the shrinkage and expansion of asphalt binder
Result: Rectangular-shaped cracks appear on the pavement
Cause: Thin layering of asphalt mix or poor sub-base
Result: Cracks on pavement due to overloading
Poor quality asphalt mix or its inappropriate layering makes pits in different areas of the asphalt pavement. These pits hold water and cause more damage to asphalt paving.
Water is the greatest enemy of asphalt pavement and mainly gives rise to the pothole formation in it. Weather changes and heavy traffic also contribute to pothole formation.
Moreover, these potholes especially emerge during the freezing and melting cycle at the end of winter and early spring. However, this type of damage can be reduced by following proper preventive measures.
The poor bonding between asphalt and aggregate results in stripping. This damage causes the surface to displace and forms cracks in the pavement.
Base failure is the worst type of asphalt damage. Inappropriate water drainage, overloading, poor installation, or weak support system develop a problematic sub-base.
Unfortunately, this base failure can only be treated by removing the whole surface layer from the top.
Is Asphalt Repair Possible?
Although the asphalt damages are not highly hazardous, it is necessary to repair them on time to avoid further loss.
These asphalt damages can be treated by using the following techniques properly:
Where is Asphalt Paving Applicable?
Asphalt paving is applicable in various sectors. The two main sectors that make use of asphalt paving are as follows:
Commercial paving includes private properties like:
Tennis or basketball courts
Golf cart paths
2.Residential Asphalt Paving
Residential asphalt paving includes private residential areas like:
How Much Budget Does Asphalt Paving Require?
The cost for the installation of new asphalt depends on a few factors, including:
Excavation of the area to be paved
Foundation of underground gravel
Quantity of asphalt required for the project
Quantity of other materials required for asphalt paving
Transportation of asphalt mix from the plant to the working site
Installation of drainage system
Current oil prices
However, the repair of asphalt pavement does not require a big budget. Generally, a repaving project needs an estimated cost of around $1.75 to $2.25 per square foot.
