Navigating the road ahead with tech-driven construction and maintenance

In this interaction, Sujit Mule shares his thoughts on how technology is reshaping the construction, maintenance, and performance of Indian roads.

How is predictive maintenance driving better performance of large-scale infrastructure like roads and bridges?
Predictive maintenance is vital because it prevents failures before they happen. Roads and bridges handle immense loads daily, and even minor flaws can develop into major issues if left unaddressed. Predictive tools help identify early warning signs—such as stress, cracks, and corrosion—using sensors and real-time monitoring. For example, sensors placed in bridge joints or under asphalt layers can track vibrations, pressure, and moisture. This data, analysed using machine learning, tells us when and where repairs are needed, often before the problem becomes visible. In India, where infrastructure is exposed to stressors such as heavy rainfall, temperature fluctuations, and constant traffic, this approach helps extend asset life, lower repair costs, and reduce downtime.

How is road construction in India turning tech-driven? And how has Rachana Construction leveraged technology?
Road construction in India is evolving fast. Several technologies are enhancing the process, making it faster, more precise, and more sustainable. What once took weeks now takes days, with much higher accuracy. At Rachana Construction Limited, we use drones for land surveys. These aerial surveys enable us to plan more effectively, identify design conflicts early, and minimise unnecessary work on-site. Automation is another key factor driving road construction. GPS-guided machines now handle earthwork and paving with consistent results, improving surface quality and reducing manual errors. Technologies like cold in-place recycling enable us to reuse old pavement material directly on-site. This cuts transport costs, lowers carbon emissions, and saves time. Digital project monitoring tools are also gaining ground. Engineers can now track progress, flag delays, and make changes from a central dashboard, even across remote sites.

How is technology redefining road construction, maintenance, and repair?
Technology is turning roads into smart assets. GPS and laser-guided machines now grade land and lay pavement with extreme precision. This means stronger foundations and longer-lasting roads. Maintenance is smarter, too. AI models analyse satellite images to detect early signs of surface wear, water retention, or cracks. Smart sensors embedded in roads collect data on traffic and stress. Alerts are triggered when pressure reaches the threshold limit or cracks begin to form, signalling inspection requirements. Quick-setting materials and modified binders are revolutionising repair, enabling roads to reopen faster after maintenance.

The most crucial element for a road’s stability and performance is proper drainage. What are the key considerations adopted by you to ensure proper drainage?
Water is the biggest enemy of roads! Water seepage into the subgrade or accumulation on the surface weakens the entire structure. This is why drainage planning must begin from day one. One important strategy we have adopted is ensuring proper slope and camber so that water flows off the surface quickly. Additionally, lined side drains are laid to match the terrain, and outlets are placed strategically to prevent water from pooling or eroding the base. We also use granular sub-base materials that allow controlled water movement without getting washed out. It is important to ensure that drain maintenance continues even after the road is built. Even the best drainage design fails if silts and waste block the outlets.
