Paving Of Roads The Professional Way

Streets can have a significant part in interfacing individuals to a nation. It makes it simpler for individuals to get to assets that are far away. Subsequently, the accessibility of great streets in a nation will improve financial development. Actually, the presence of great streets in a nation is more helpful to society overall. For example, the travel time is decreased because of the smooth street surfaces. This responsibility for street paving isn’t only for the public authority. Private people may likewise be associated with the cycle. It could be your own parking lot in the house compound.

In this article, we will examine street paving, overall, you will be astonished that street paving is additionally done around us by people. In this situation, we mean they are financed by the individuals. This article expects to give you the general learning about street paving. We will examine the cycle of street paving, the kinds of black-tops before we going into a portion of the black-tops that people can fabricate.

How Is Paving Of Roads Done?

First, you might ask yourself what is road paving? In defining this term I will start by definition of paving. Paving is the act of making a surface hard and flat. Therefore, road paving is the making of roads surfaces hard and flat for traveling. Road paving did not start yesterday it’s a process that has been refined by different people over centuries to come up with what you actually see. The oldest paving done by humans dates to around 4,000 bc. These were constructed by the Mesopotamians.

Types Of Road Pavements

Depending on the materials used on the surface course, road pavements can be classified into two ways. Flexible pavements, and rigid pavements all these are discussed in detail below. We will give the advantages and disadvantages of each type of road pavement.

Flexible Pavements

The distinguishing feature of this type of pavement is that it’s made using bitumen which is obtained from crude oil. Below the surface course is all the other three layers the sub-grade, sub-base course, and the base course. Materials with a high degree of strength are usually near the surface of the pavement. Majorly around the base course. These types of roads are very famous and can be found in many countries of the world. The reason could be due to its low in construction costs. These flexible pavements are made in such a way that the weight of the vehicles is transmitted to the bottom layers.

  • Roads can be used 24 hours after construction.
  • They are cheaper to construct as compared to other road pavements.
  • Deformations caused by heavy wheeled vehicles can be recoverable.
  • They require maintenance nearly every year. Therefore, they are costly in the long run. However, these repair costs are relatively cheap.
  • There is a general fear of a rise in the price of bitumen in the future. This is because of the forecasted decline in the supply of crude oil in the world.
  • It has a short lifespan.

Most of the weakness of these types of roads are as a result of using bitumen. Bitumen will react differently with variations of weather. For instance, an increase in temperature would cause it to melt. On the other side, low temperatures would cause bitumen to freeze causing cracks. However recent researches have shown that this could be reduced by the use of a chemical reaction modifier.

Rigid Pavements

They are sometimes referred to as concrete pavements due to being made of concrete. These types of pavements will have two layers before the surface layer made of the sub-base and the base course. The weights of vehicles are transmitted over a wide region.

  • Concrete is readily available as compared to bitumen in many countries
  • Concrete is not affected by weather conditions such as which temperatures and cold temperatures.
  • Has a long life. The cost of maintenance is lower as compared to flexible pavements due to the frequency of maintaining the roads. However, an instance of a maintenance cost is higher than of flexible pavements.
  • Saves on the stone aggregates to be used in other layers.
  • One of its major characteristics is the high initial cost.
  • It will require more curing time after its construction a minimum of one day for anything to be plying on the pavement. For places with high traffic, this curing periods might not be observed.
  • In some instances, joints are required for expansion and contraction.
  • Deformations due to heavy wheeled vehicles are not recoverable.

Therefore rigid pavements are ideal when there is plenty of money and in places where there are low traffics.

The Process Of Road Paving

The process will involve some steps which are explained below. We have given the simplest of these procedures. They have been simplified to three: the planning stage, excavation and earthing and paving. However simple they are this is what actually happens in the real world. These simple steps will take even years to finish.

Paving Highways

Most people have seen the large road rollers go back and forth on highway construction sites as they apply the finishing touches to a new asphalt surface. Most people probably think that is all that is involved in laying a new highway surface. But before the road rollers can do their part, there are several steps that must take place first before they can create that smooth, shiny black surface.

Before anything happens, the area must be demolished and cleared. Trees and debris must be hauled away from the site using small bobcats and forklifts, front loaders and dump trucks. Once the area is clear, the grading and sloping process begins. This is where the surface is prepared. Careful attention is given to drainage, as water is one of the main contributing factors to damaged asphalt.

Once cleared, graded and sloped, the sub-base is prepared. The sub-base provides the stable surface that will support the new pavement, playing a key role in the stability of the highway. It also acts as a frost barrier, preventing damage due to seasonal freezing and thaw. A binder is added to the sub-base, consisting of an aggregate mix with oil, creating strength and durability.

The surface asphalt can now be applied. Often a new asphalt surface will connect to other roadways and parking lots. Transitions to these access points need attention to make sure the grading is correct, and the water run off is considered. These transitions need to appear seamless. Once all these things have happened, then the road rollers take over, the final process taking place, smoothing out the gleaming black surface this will soon be the new highway.

Planning Stage

As most philosophers would argue that every good thing in this world started with an idea so is the process of road paving. There is the planning stage where everything is put into the paper before anything starts. This done at this stage are approximations of what will happen during the latter stages. Some factors are taken into consideration here like how many workers are needed. What is the estimated cost of the process and determining the weather conditions during the road construction? The process is never a simple one.

The approximations have to be done in such a way that they don’t deviate away from the real outcomes. Generally, all things are laid into a paper. Nothing has started in this step.

Excavation and Earthing

This is where the initial road construction process begins. Most of the land surfaces have bushes, shrubs, and grasses. These are what we remove at this stage. Once they are removed, the process of mounting and grading can begin. Mounting will give the road its shape while grading will make it level. Generally, what this step does is the preparation of the road for the next procedure known as paving.


This is the final procedure in the process. At this step, the concrete or bitumen is poured onto the surface. The process here is to make it flat. However, there are some other layers that are laid first before this last step of pouring bitumen or concrete. These layers are, sub-grade, and sub-base course and base course. Depending on the type of pavement one is omitted. For flexible pavement, all the layers are included while for rigid pavement only two layers are needed. The sub-grade layer is always omitted.


This is the layer at the bottom. The material used in this layer should be free of organic matter so that it can easily be compacted by a roller.

Sub-base Course

It is the second layer from the bottom. It is usually made of granular materials. And can be omitted if the sub-grade is of higher quality. The quality of this layer will ensure a road with low maintenance. The materials used for this layer is unbound granular materials such as stones and concrete.

Base Course

It’s the layer immediately under the bitumen on the surface. It’s a layer that is always subjected to loading pressure. Care should be observed in this course.

Some of the common pavements individuals can construct

The most common ones are driveway paving and parking lot paving. These types of pavements have one thing in common in that they cannot go for long kilometers as compared to the general road pavements. They can even be on your own premises. They can, therefore, be said to be private property. They are still maintained by the individuals themselves.

Driveway Paving

Having a nicely paved driveway is very important for your home as it could increase the value of your home. Basically, everything used to make these pavements comes from what we have discussed above. The type of paving will depend on the type of materials used but as before we had cited as being made of either tar or bitumen. These types of pavements can be made to look beautiful depending on your own needs. So it’s therefore wise to consider the advice of an expert when making such a decision.

The price of the driveway pave ways will vary depending on the paving companies that you choose. Sometimes the price will be significantly higher if you had no ready-made road. But if you consider the factors that we had given you above you surely should come up with the right company for this job.

Parking Lot Pavement

Another type of pavements built to be individuals. They can be somebody property. The size depends on the number of cars that will always be parked there. For a home parking lot, it could small enough for two cars. While for large business enterprise it will be large enough to accommodate say a hundred cars. These types of pavements have nothing different

From here now we give you the basic knowledge needed by anybody who wants to construct any of those two. First, we give the factors to consider when selecting a road paving and we will give you reasons why to consult an expert.

How To Pick Road Paving Companies

Price is always a common factor when we want to acquire anything. Most of the times we are going for those that are cheaper. According to experts, it’s better to incur more initial costs and acquire something that has good quality. But if you are considering choosing a paving company there are other factors that are more important than the price that should be considered. Below we will give the factors to consider when trying to come up with a good decision.

a.  Check for the equipment

For high-quality service, the provider must have the necessary equipment needed for the work. Always check if the company has the right types of equipment for the job. This will go a long way in ensuring the quality of the paving company.

b. Is the company insured?

Insurance should be a necessary requirement when choosing a road paving company otherwise you might find yourself incurring other costs that might arise from accidents. To avoid such costs ask if the company is insured before any proceedings.

c. Down payment

Some companies will ask you to pay a down payment. You should not pay any down payment to a paving company. Unless the construction will incur above $10,000. Reputable paving companies never ask for any down payment. The reason why you are discouraged from making a down payment is to prevent your money from landing into the hands of fraudsters. Sometimes, if you pay the down payment.

d. Labor

Here you should consider the quality and quantity of labor hired by the company. It should have a qualified work staff and the number of work staff should be enough. Qualified work staff will guarantee you that the company offers quality service. Having the right number of workers will stop you from having delays as to when the project should end.
