Our driveways and roadways are frequently lined with asphalt concrete pavements, which offer a smooth and long-lasting surface. But even with their initial resilience, these pavements may eventually experience a number of problems. By knowing why asphalt concrete deteriorates, we can effectively address these issues and preserve the integrity of our surfaces.
Weather is one of the main factors that damages pavement. Too hot or too cold temperatures can cause the asphalt to expand and contract. This continuous movement may cause deterioration in the form of cracks. Furthermore, a lot of rain or snow can seep into these cracks and erode the pavement even more.
The amount of traffic is another crucial factor. Constant use and large vehicles can seriously strain the pavement. This may eventually cause ruts and depressions, which would make the surface uneven and less safe for driving. To manage these stresses, timely repairs and proper maintenance are essential.
Lastly, issues with pavement can also be caused by subpar construction techniques. Improper installation methods or inferior materials can cause premature failure. The lifespan of asphalt concrete pavements can be increased by making sure that appropriate construction techniques and high-quality materials are employed.
| Cause | Description |
| Heavy Traffic | Excessive vehicle weight and frequent use can wear down the surface. |
| Water Damage | Water seeping into cracks can cause the pavement to weaken and crack further. |
| Temperature Changes | Extreme heat and cold can cause the pavement to expand and contract, leading to cracks. |
| Poor Construction | Improper mixing or layering of asphalt can lead to early deterioration. |
| Underlying Issues | Problems with the ground beneath the pavement, like poor drainage or unstable soil, can cause damage. |

Types of defects
Different structural infractions of the road may occur. They are categorized as follows in this regard:
- Drawdowns. In this case we are talking about distortion of the road profile. The drawdown looks like a depression with gentle edges.
- Tracks. A very common problem is distortion along the knurling line.
- Breaks. Serious damage affecting the structural layers of asphalt concrete.
- Chipping. This happens when parts of the mineral composition begin to fall out.
- Edge fractures. It is not uncommon to see ragged edges appear where the road meets the side of the road.
On the road surface, there may also be shifts, waves, peeling, and single or grid-shaped cracks. The range is just enormous, and there are even more reasons why these defects appear.
Pavements made of asphalt concrete encounter a number of difficulties that eventually cause them to collapse. Heavy traffic volumes, severe weather, inadequate maintenance, and poor drainage are important contributing factors. These factors have the potential to compromise the pavement’s longevity and safety by causing cracks, potholes, and surface deterioration. Planning better building techniques and upkeep plans to increase the lifespan of asphalt pavements is made easier by having a better understanding of these causes.
Why asphalt concrete is destroyed
The primary issue is related to moving vehicles’ high power loads. Additionally, the soil’s chemical makeup and the surrounding environment have an impact on the quality of asphalt. However, there are numerous other typical causes.
Design errors
Nobody will be shocked to learn that this occurs frequently. Ideally, all relevant research should be completed before the route is laid; this includes a study of the soil’s condition, climatic characteristics, the intensity of the car flow, etc.
Road structures will soon become the subject of jokes if none of this is considered. The integrity of the coating is compromised because everything is completed quickly, and the asphalt soon starts to sag.
Using old installation methods
Although it would appear that progress is always moving forward, you can occasionally observe how a hot asphalt concrete mixture of the most basic kind is applied to highways. Even though it has been around for a while, the technology is out of date now. This makes sense because bitumen of inferior quality is a component of these mixtures. It is unable to supply the required power.
The use of polymer-bitumen compositions in modern technologies increases rather than decreases the properties of the future route. Additionally, a vast array of additives that enhance material adhesion, resistance to atmospheric phenomena, and cracking are readily available on the market today. As a result, new compositions and laying methods for asphalt have long been developed.
Violation of the technological installation process
We also frequently run into this issue. In the heat, cold, and snow, road structures are built. However, other errors may also occur. For instance, the solution lost part of its properties if the asphalt concrete was transported improperly. Such a mixture actually cannot be laid.
Additionally, the solution is supplied at the incorrect temperature when using the hot laying method. It would seem that studying this technology was possible after all these years, but apparently that isn’t always the case. The canvas may deform quickly even if air bubbles remain after installation and have not been eliminated. Additionally, the road will peel and crack if the solution is overly thick.
Exceeding permissible loads
Once more, determining the roadway’s daily throughput is crucial before approving the project. If the asphalt is laid for an average level of loads and the traffic flow is too high, the route’s service life will start to decline exponentially.
As you can see, there are many reasons, the most common of which are human laziness and inadequate qualifications. However, a problem exists; how can it be resolved?
Understanding the causes of asphalt concrete pavement destruction is crucial for maintaining and extending the life of our roads. Regular wear and tear, due to traffic and environmental conditions, inevitably leads to some deterioration. However, identifying the root causes can help in taking preventive measures to reduce damage and enhance road performance.
Among the frequent problems are inadequate drainage systems and shoddy building techniques. Potholes and cracks are caused by the pavement’s structure being weakened by water infiltration. Pavement deterioration can also be accelerated by poor mix designs and improper compaction. It is imperative to tackle these concerns at an early stage in order to avert more serious issues later on.
The secret to managing pavement health is timely repairs and routine maintenance. We can guarantee a safer, more resilient road network by being proactive and taking care of small problems before they get worse. The lifespan of asphalt concrete pavements can be greatly increased with appropriate maintenance, which is advantageous for infrastructure and drivers alike.
