5- Types of Durable Materials for Roads Construction

Any well-made road’s surface is the focus of observation, a serious element that affects durability, safety, and complete performance. A road surface is the upper layer of road pavement, acting as the border between vehicles and the underlying structure.

This serious element is considered to bear the effect of traffic, weather conditions, and other environmental aspects. Road surfaces are designed for durability, safety, and optimal performance, ensuring smooth driving experiences and pavement resilience.

Here, we will discuss five types of durable materials for road construction.

Block Paving

Using stone sets for block or cobble pavement goes back hundreds of years. The method is still standard in cities and urban areas, though expensive. The start of industrial concrete blocks has reduced the price of block paving.

Due to their accessibility, mixed colours and surfaces are increasingly popular in residential developments and lower-speed roads in urban areas. Block paving has also been verified as appropriate for heavy-duty pavements in airports and container-managing services. Large paved areas like parking lots favouring permeable block paving solutions.

Cement Concrete

Cement concrete is by far the most durable and rugged road material. It is also famous for its flexibility and comfort of construction. The ingredients that go into manufacturing it is cement, water, aggregates, and chemical admixture. One of its main disadvantages is that cement-based concrete increases carbon emissions.

Although its original price is high, considering its extensive span of life and low upkeep, the life-cycle price of concrete roads becomes slightly low. Concrete can also be used to raise the tensile strength of present pavement coatings.

Because of cement’s brilliant binding property, well-mixed concrete comprises insufficient spaces and rapidly sets and strengthens. When preserved with water, concrete offers a durable and long-lasting road surface that can bear frequent effects from heavy commercial vehicles.

Asphalt Paving

Asphalt paving is commonly used in building roads and highways because of its frequent benefits. One of the most important benefits of asphalt paving is its durability. Asphalt is a stretchy material that can resist heavy loads and risky weather conditions.

It can enlarge and shrink with temperature variations, making it less prone to cracking and breaking. This durability makes asphalt paving a perfect option for high-traffic roads and highways.

Carbon Lock

Carbon Lock contains biogenic material that grips and ‘locks in’ CO2 during its life span, even when recycled. It is also formed using the ERA warm mix procedure, which permits the asphalt to be manufactured at a lower temperature. Consequently, the product offers a minimum 25% reduction in carbon emissions associated with a typical hot mix.

Together with the reduced production temperatures, the asphalt’s high bitumen content and minimal void also contribute to its exceptional durability. Road users will experience less disruption and increased efficiency with this product, which may also be laid as a single layer.


Granular bases, sub-bases, bituminous mixes, and cement concrete are all built with aggregates. They are also the vital element of a moderately cheap road recognized as water-bound paving.

Stone aggregate, frequently called mineral aggregate, is the most significant element of road construction materials. Natural rocks are fractured to produce fine aggregate (like sand) or coarse aggregate (like gravel).

Similar to soil, aggregates also require an estimate by a road engineer to confirm that they are robust and durable enough for a definite project. Their origin, the mineral components they contain, and the type of bonds that hold the components together all affect these qualities.
