Introduction to Pavement Engineering, its Recent Development & Future trends

Reading Time: 3 minutes

What is meant by pavement engineering? What is essential for the field of pavement engineering?

Pavement engineering comes under the department of civil engineering, where the engineers are trained on how to use different methods of engineering to design unbreakable and manageable pavements. Sometimes, instead of making new pavement, engineers are also educated about how they can maintain an already-designed pavement to make it more strong and more effective.

Frequently, streets and highways are constructed using pavement engineering. The role of the development of new pavements in various areas as well as their preservation comes under the role of a civil engineer who should be well experienced in the field of pavement engineering.

The maintenance and preservation of pavement engineering concern the judgment of the engineer who has to make an efficient judgment which helps in making a long durable pavement with little to no extra costs. 

The knowledge of hydraulics (department of engineering that is concerned with transportation of different kinds of liquids using pipes for force and direction), soils, and other material characteristics is essential for the field of pavement engineering.

What are the recent developments & future trends of Pavement Engineering?

Previously the layer of pavement was checked for thickness so that the pavement remains preserved and long-lasting using the empirical method of engineering

Recently in pavement design, the collected knowledge which was genuine regarding the climate and traffic in design was only achievable because of the adoption of methods by the engineers from empirical to mechanistic-empirical methods. In this method, the principles of sounds were used to predict the strain and stress in the construction.

In today’s time, there is a specific distinction in the characteristic that is observed by designers between the designed and the constructed pavement. This is why the current pavement patterns that are practiced and the formation and sustenance of these pavements must be extremely developed to meet desired outcomes.

Pavement Engineering Recent Trends are –

1) The effective design is made after using all the data that was collected or obtained before pavement construction.

2) The data collected should not be based on predictions and should be obtained from the current traffic intensity and burdening. 

3) The temperature of pavement within the separate layers should also to accumulated to implement a competent solution.

4) Mix design to be used for pavement design should be used to attain a more effective and cost-cutting clarification. 

5) Utilization of innovative technologies for the construction of new pavements, as well as for the maintenance of already constructed pavements.

By the installation of grating sensors in the pavement for monitoring, we can observe the real-time stress and strain value on the pavements.

In today’s industrial technology era, the use of asphalt and concrete materials are mostly used for pavements since they provide the desired result which is also the reason why they are preferred over any other materials.

However, in upcoming years, with an increase in the population of human beings, the industries of asphalt and concrete will need to adapt to change more as well. They will need to provide more innovative and efficient solutions for the maintenance as well as for the construction of new pavements.
