What are the modern construction materials used for construction of pavement?

Material	Advantages
Fly ash	Lightweight, used as binder in stabilized base/ sub-base due to pozzolanic properties
Metallic slag – Steel slag – Nonferrous slag	Higher skid resistance Light weight ( phosphorus slag)
Construction and demolition waste	More strength, can be used as aggregates granular base

What are roads made of in India?

In Jamshedpur, India, roads are created from a mix of plastic and bitumen. In Indonesia roads are also being built using a plastic-asphalt mix in many areas including Bali, Surabaya, Bekasi, Makassar, Solo, and Tangerang.

What is new technology in road construction?

Self-healing concrete and intelligent compaction are other emerging technologies in the area of road construction materials and machines. Smart highways, intelligent transport management solutions, advanced traffic management systems, project monitoring information system, etc.

How plastic can be used in road construction?

The waste plastic is shredded & coated over aggregate & mixed with hot bitumen and resulted mix is used for pavement construction. This will not only strengthen the pavement and also increases its durability. The titanium-dioxide is used as a smoke absorbent material, which will absorb the smoke from the vehicles.

Can we use plastic in road construction?

Plastic roads consist of 6-8 per cent plastic, while 92-94 per cent is bitumen. Union minister Nitin Gadkari had announced the usage of plastic waste in road construction in 2016. The MCG has now made the use of plastic waste mandatory in the construction of arterial roads.

What are the recent breakthroughs in the construction industry?

The most recent breakthroughs in hardware components are inspiring. Now, better collaboration, discovery, and analytics tools are driving the industry. As needs change, manufacturers have created remarkable tools to get the job done. This has been a growth area for construction since the inclusion of digital tools.

What are the latest advances in roadbuilding?

4.Computer modelling: “The advances in roadbuilding are coming in engineering areas,” says Gene Syvenky, chief executive officer, Alberta Roadbuilders & Heavy Construction Association. Computer modelling is being used much more for designing structures, benefiting taxpayers and resulting in better performing roadways.

What are the new developments in the construction industry?

Apart from the basic structural materials, modern projects require a variety of secondary materials for a variety of purposes such as construction chemicals, waterproofing materials, durability aids etc. The paper highlights some of the recent developments. Concrete Design and Construction Practices today are strength driven.

Why do Indian cities use waste plastic to build their roads?

As of 2015, any Indian city with a population of at least 500,000 is required to construct their roads using waste plastic as a core material, in efforts to promote greater pollution control and environmental sustainability for Indian communities.
