Hilly terrains are challenging for construction due to steep cuttings, soil retention, drainage, landslides which may lead to many calamities and loss of life.
Road safety has been one of the major concerns across India. Every year, it is observed that road accidents either on highways or hilly areas have been endangered for human lives. Hilly regions are more vulnerable to natural disasters causing landslides, debris falls, and other rock fall events, and hence, becomes critical for infrastructure such as roads and bridges. Some infrastructure firms are providing innovative solutions that offer technical expertise to deliver versatile, cost-effective, and environmentally sound solutions, which are critical in preventing such accidents in the future. In an exclusive conversation with the Financial Express Online Vikramjiet Roy, the Managing Director of Maccaferri in India and the Regional CEO of the India South East Asia Pacific (ISEAP) region at the Officine Maccaferri Group talked about how they are developing solutions to ensure safer road travels. Excerpts:
For road safety, what are the products / solutions developed by Maccaferri in India – talk on geosynthetic solutions.
We have developed unique solutions and products to curb road travel mishaps, some of the effective and efficient solutions are with the use of Geosynthetics. The polymeric composition of geosynthetic products makes them suitable for use in the soil wherein very long-term durability is key. One such application that contributes to road safety is called Asphalt Reinforcement Geogrid. This product when used reduces the need for frequent pavement maintenance by preventing potholes and cracks in the roads.
The other example is Drainage Composites that facilitates the proper drainage in pavements and reduces the frequency of potholes and settlements. Geosynthetics have a wide range of applications and are used in many geotechnical, transportation, geo-environmental, hydraulic, and private development applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, erosion control, sediment control, landfill liners, landfill covers, mining, aquaculture and agriculture. Geosynthetics are available in a wide range of forms and materials such as Geomembrane (MacLine), Geotextile (Mactex), High Strength Polymeric strips & geogrids for Soil Reinforcement (ParaWeb, ParaLink), Erosion control mats (MacMat), Composite products- Drainage solutions (MacDrain), etc. Other innovative and effective solutions for Roads and Highways Include:
Double Twist: For safer roads, it is important to develop innovative, durable, cost-effective and sustainable products. One of our products includes Double Twist mechanically woven wire mesh products such as – Gabions, Mattresses and Terramesh. Gabions are provided to act as embankment protection on the sides of the proposed road whereas the Terramesh System is a modular system use to form rock-faced reinforced soil walls and embankments.
Rockfall Protection: Rockfall protection and natural hazard mitigation systems are key elements in the security and safety of roads. With decades of experience, we offer a wide range of systems to stabilise rock faces, soil slopes and snow masses. Certified and tested by leading institutes and in accordance with the latest standards, our solutions are designed using state-of-the-art modelling software and techniques. Our products include Rockfall Netting, Steel Cables and High Energy Absorption Panels for rock fall Prevention, Rockfall Barriers, ErdoX, Snow Structures
Highlight of the projects (Completed and ongoing related to road safety)
We have completed many road safety projects in mountain areas and highways. One of our recently completed projects includes Lambagarh in Uttarakhand. The slides in this area are very steep and the landslides have been active since 1980s affecting traffic in every monsoon. The site is located on a path taken by yatris to the Amarnath caves and every year they have been exposed to the greater danger of constant and unpredictable slides in this spot. We worked with the client to construct a flexible reinforced soil wall with a customized methodology and products including gabions as facia (Maccaferri’ s Terramesh® system) and high strength geogrid (ParaLink®) as reinforcement towards the valley side for shifting the road from its current position. The stones and backfill material were locally sourced. Also, we successfully completed Mumbai Pune Expressway Project by constructing gabion walls. During monsoon, this area experiences rockfalls, and becomes slippery causing traffic and road mishaps. It was necessary to address this situation and therefore, we designed gabion walls and retaining walls. We have also successfully provided mitigation solutions for rockfall protection in the Lonavla stretch of the Expressway. There are multiple other road safety projects ongoing in Uttarakhand which we are aiming to close before the onset of monsoon.

What geographical challenges the company face in ensuring road safety?
There are multiple geographical challenges involved in ensuring road safety. First and foremost, is the still slow (although well increased in comparison to a decade back) pace of adoption and mass implementation of globally proven technologies like Asphalt Reinforcement, Drainage Composites, Basal Reinforcement Base and Sub-base stabilization, etc. which could significantly improve the quality and long term maintenance of the Roads and Highways being built in the different geographies of our large nation. Then, is the seasonal impact – any projects in hilly terrains take a longer duration to complete. Due to the rainy or winter season these projects are constrained to a shorter working period. Third is the lack of education and skilled manpower. This is one of the biggest challenges which is faced by a lot of industries in India. India has resources and labour, but they lack knowledge and skills for innovative solutions provided by us. Many of the projects or activities involve skilled knowledge and expert handling. It is necessary to address this and develop a solution that benefits everyone. Hence, to ensure road safety, we need to train and educate the labour, contractors and consultants with better solutions & measures. Lastly, there are limited access points in remote areas which affects delivery of materials.
