How to Lay Asphalt Pathways in 7 Steps?

by Naman A. Well-Motivated Digital Marketer

Asphalt pathways are comparatively cheaper than concrete ones and the go-to choice for most people. You may go to an Asphalt company, and they will finish the job with finesse and diligence; however, do you have a basic idea of what it is and how it’s done? 


So, here’s a small guide to give you a quick read about Asphalt pathways. We have three sections in this guide — Definition, process, and types.


First things first! 

What is an Asphalt Pathway?


As the name suggests, Asphalt pathways are pathways made with a material called Asphalt. Usually, a pathway may be made with different materials, from concrete, and asphalt, to cement. The top choice of all is Asphalt. 


Asphalt is made of stone and sand, similar to concrete. However, the fundamental distinction is in their adhesive materials. Asphalt is obtained from petroleum, whereas concrete is made from cement. This single variation results in a wide range of differences between the materials.


Asphalt pathways provide a professional, clean first impression. It is also more affordable than its alternative concrete. However, the downside is that the durability of Asphalt pathways is less than that of concrete. 


How to Lay Asphalt Pathways?


Step 1: Demolition and disposal 


The first phase in the asphalt installation procedure is to remove the current surface. It might be asphalt, concrete, or pavers, but it should be removed first to begin the process. 


Many people ask if they can lay asphalt pavement in their homes on their own, and this part answers that question. Heavy machinery such as tiny bobcats and forklifts, as well as front loaders and huge dump trucks, are needed to deconstruct the old pathway. So, in most cases, this is a job for professionals. 


After it is demolished, the debris is then cleared. Depends on the Asphalt company you hired because some also recycle this old asphalt or concrete and turn them into usable new asphalt. 


This not only helps alleviate the expenses but is also eco-friendly. 


Step 2: Grading and Sloping


When the elevation of construction is lower than the grade of the soil surface or landscape, grading and sloping are required. This is vital to ensure that surface water flows away from your property rather than towards it. 


Grading allows the final pavement to drain properly, preventing early degradation. And the fitting percentage of grading varies depending on region, landscape, and other variables.


Water is a primary source of damage to asphalt, including potholes, cracks, and heaving; thus, proper water drainage is essential.


Step 3: Set the sub-base


This is the most important part of the process, as the sub-base creates a solid foundation for the fresh pavement. The sub-foundation also acts as a frost barrier, reducing winter damage caused by freezing and thawing. 


Base thickness, base stability, and compaction are critical phases in the installation. If the sub-foundation is not properly compacted, the asphalt surface on top will not last for many years.


Depending on the situation, the aggregate sub-base is made from crushed rocks or concrete or recycled asphalt. The project requirements and estimated traffic load determine how the base should be prepared.


Step 4: Setup of the base course 


Depending on the project and its needs, the base course is a layer of aggregates and binders that rests directly on the compacted sub-base or subgrade. This material is compressed after it has been distributed to lend strength and stability to the asphalt pathway that will lay on top of it.


Step 5: Install the Wear Course 


The Wear Course is the surface asphalt pathway layer designed to withstand traffic loads while resisting environmental wear and tear. This is also called the Surface Course. 


This layer is made up of tiny gravel, sand, and liquid asphalt (the binder).


Step 6: Compaction


Now, it's time to compress and smooth the surface. Compaction secures the asphalt-coated aggregates together, which helps the completed pavement solidify. This is important to withstand pavement deformation over time. 


Compaction also guarantees that no tiny bits of aggregate stick up through the new, smooth surface and helps enhance the pavement's long-term durability by lowering permeability.


Step 7: Butt joints and transitions


Most asphalt pathways connect to the old ones on highways or driveways. So, the contractors must devise a method to make the transition from old to new surfaces as smooth as possible. 


Butt joints are the points at which old asphalt pavement joins the new asphalt pavement. These transitional zones require specific care to maintain proper grading and water run-off. 


Butt joints and transitions are essential to ensure that drivers and pedestrians do not detect any surface differences.


Types of Asphalt Pathways


There are Five primary kinds of Asphalt pathways, namely:


  • Porous asphalt

  • Perpetual pavement

  • Quiet pavement

  • Warm-mix asphalt

  • Thin overlays


Conclusion


These are the steps in the process of asphalt pavement that should be followed by your asphalt paving contractor to ensure that your new asphalt surface will last for years and serve your house, business, or city well.
