Mobile Bridge Inspection Unit (MBIU)

The Mobile Bridge Inspection Unit (referred as MBIU) is an Electro-mechanically driven Articulated Structure mounted on a vehicle (a truck) as an aid towards proper inspection of bridges or similar infrastructures by enabling an inspection team of 3-4 persons carrying instruments access to the underside of bridge decks over flowing rivers or gorges.
Utilization of Municipal Solid Waste (MSW) in Road embankment

About 65-75% of segregated Municipal Solid Wastes can be used for embankment construction.Leachate studies indicate that MSW is a non hazardous material as concentration of heavy metals is within the permissible limit.Typical design cross sections have been arrived for 3m and 5m height MSW embankment.
Patch Fill-Pothole Repair Solution for Bituminous Roads

Patch-fill solution is useful for faster filling of potholes in bituminous roads without causing any environmental pollution and hindrance to roads users. Potholes filled by Path-fill shall be long lasting.
India hails success of first ‘steel-slag road’

A stretch of six-lane road experimentally paved with slag from steel-making in India has been shown to weather the beating from thousands of heavy trucks even though the surface is 30% shallower than that of roads paved with natural aggregates. Slag is made up of impurities melted out of the ore during the steel-making process. The trial, guided by the Central Road Research Institute (CSIR-CRRI) and sponsored by ArcelorMittal Nippon Steel (AM/NS).

Dr. Chalumuri Ravi Sekhar, Director, CSIR-Central Road Research Institute

Dr. Chalumuri Ravi Sekhar, Director of CSIR–Central Road Research Institute (CRRI), is a distinguished transportation engineering professional with over two decades of experience spanning research, consultancy, academic mentorship, and institutional leadership. Over the years, he has played a pivotal role in strengthening CRRI’s contributions to national transport policy, infrastructure planning, and technology-driven innovation, aligning the Institute’s research agenda with India’s evolving mobility and sustainability priorities.

Dr. Ravi Sekhar obtained his Doctoral degree in Transportation Engineering from Kobe University, Japan (2008), where his research focused on measuring travel time reliability of road transportation systems, supported by advanced exposure to Intelligent Transportation Systems. He earned his Master of Engineering in Transportation Engineering from IIT Roorkee (1999) and his B.Tech in Civil Engineering from JNTU Hyderabad. His academic and professional expertise encompasses traffic engineering, transportation planning, travel demand modelling, travel time reliability, route and mode choice analysis, ITS, GIS/GPS applications, highway geometric design, and the application of artificial intelligence and soft computing techniques, including Artificial Neural Networks, to transportation and road safety challenges.

Dr. Ravi Sekhar has led and contributed to more than 40 major R&D, sponsored, and consultancy projects, many with direct policy relevance and field implementation. His notable contributions include leadership in the development of the Trip Generation Manual for Indian Cities, AI-based Automatic Vehicle Counting and Classification software, evaluation of Bus Rapid Transit systems, preparation of Comprehensive Mobility Plans for Indian cities, and advanced studies on road safety using ADAS and DMS technologies, electric vehicle infrastructure, and environmental impacts of traffic.

An accomplished academic and mentor, Dr. Ravi Sekhar has authored over 100 research publications in reputed national and international journals and conferences, in addition to books and book chapters. He has successfully guided 27 M.Tech dissertations and six Ph.D. scholars, and regularly teaches advanced courses at the Academy of Scientific and Industrial Research (AcSIR). His contributions have been widely recognized through prestigious honours, including the IRC Pt. Jawaharlal Nehru Birth Centenary Award, CIDC Achievement Award, and the CSIR-CRRI Best Scientist Award, reflecting his sustained impact on transportation engineering research, policy, and practice.
