In civil engineering, there are two probable reasons for pavement failure.
A lot goes into the construction of pavements for road users. Lots of taxpayer money is involved when the government at various levels sponsors these projects and it is only ideal that they serve their purpose.
The same also applies when an individual or individuals join hands to construct pavements. This is why it is necessary to do all that’s reasonably possible to keep these constructions in the right state and shape. If you would like to have an idea of how much goes into road maintenance every year, you can click here.
The truth is that even the best-constructed pavements will give in after some time and this is where maintenance and repairs come in. However, some begin to show signs of premature failure for several reasons.
When this happens, the repair process has to be the right approach. This is important as some repair approaches only tackle a bit of the problem and not everything. This is why the full depth reclamation is strongly recommended.
It has been used for quite a while and the results are usually impressive. This is as long as the right hands and minds are involved in the repair process.
We will discuss how this repair technique can help fix several causes of pavement failure in this article. You are advised to keep reading so that you can learn more about this technique’s ability to help in this regard. But first, let us discuss…
What Makes Full Depth Reclamation Technique Better than Other Repair Techniques?
Full depth reclamation is better than many other pavement repair techniques given how it does not only patch up the problem. Rather, it addresses the underlying issue by seeing to it that the base is in the right state and shape.
Chemical treatments and other necessary things are done to address the issue if this is not the case. Other than this benefit, some of its advantages include the fact that:
It saves a lot of time – This means that the road users will not be kept waiting for too long before they can use the road again.
It involves top-level planning – There is such a thing as full depth reclamation design and it is a design process that ensures that the technique is feasible. It would also make sure the right specifications are followed when making use of this technique. This is unlike other approaches that address problems only when they show up.
Cost-Effective – This is one of the benefits of engaging this repair method. One would think that its time-saving advantage and effectiveness would mean it would cost more.Surprisingly, this is not how it works. This explains why it is becoming increasingly popular.
Very Effective – Nothing beats this technique when it comes to doing a perfect job. As explained above, many alternatives only patch things up instead of addressing the very cause of the problem. Fortunately, this technique addresses the very root of the problem.
Some Reasons why Pavement Failure Happens
Every constructed road has a lifespan. This is the time that it is expected to serve its purpose until it begins to give in to things that would make it require repairs.
When the need for repairs on such constructed roads arises, the full depth reclamation is a good repair approach. In the same vein, it can also be used when the pavement failure is premature. Judging from experience, some of the possible causes of pavement failure (premature or otherwise) include the following:
Cracking
Explaining how cracking can cause the degradation of pavements is a little tricky. This is mainly because there are several kinds of cracking that can cause various degrees of damage to the pavement. Some of them include alligator, block, edge, transverse, joint, and linear – cracking.
It is tricky in the sense that while they all cause cracks in the pavement, the causes are different. For instance, transverse cracking has to do with irregularities in the base region of the pavement. This could be because of a shift in base material as a result of inappropriate paver operation or even extreme temperature.
Depression
This is a problem that could lead to other problems. This is considering how this problem causes moisture to be retained rather than dispersed. The reason for this is because of irregularities in the elevation level.
The root cause of this problem is consistent uneven compactions or sub-bases. Full-depth reclamation will be very helpful in addressing the effects of depression on a pavement.
This is especially considering how it would not only patch up the uneven elevation points with asphalt. Rather, it would straighten up the base with chemical treatment and the best that recycling affords.
Conclusion
This article has discussed how full depth reclamation can help in repairing pavements affected by two common causes of pavement failure. However, you should know that it can help with more than just these causes of pavement failure explained here.
Some other problems it can help repair include pumping, faulting, corner breakage, and punch-out. For more on this subject, you can visit: https://theconstructor.org/
Full depth reclamation is a very effective approach to repairing pavements. For this reason, it is wise to make the most of it when the need arises.
