The students of SRM University-AP are nurtured in a conducive educational ecosystem that moulds them into competent candidates ensuring research and academic success at national and international frontiers. The Department of Civil Engineering proudly congratulates Tanoogna Mallarapu, Jonnalagadda Cheritha and Gade Venkata Reddy, Final year BTech students for securing the second prize in the Paper presentation contest at the prestigious Aakaar Symposium held by The Department of Civil Engineering, IIT Bombay on March 17 and 18, 2023. The trio presented their paper titled “Study of alternative flexible pavement design approaches suitable for Maine conditions” which was part of the students’ paid internship on an overseas (USA) research project funded by the Maine Department of Transportation, USA. A total of 47 groups participated in the contest from various domains of civil engineering from all over India. The academic cohort bagged the position of runners-up under the guidance and mentorship of the faculty advisor, Dr Uma Maheswar Arepalli, Assistant Professor, SRM Univeristy-AP.

About the Symposium

Aakaar is an annual symposium organized by the Department of Civil Engineering at IIT Bombay. The event comprises workshops, lecture series, panel discussions, industrial talks, exhibitions, and other activities. The festival also includes the Seventh International Civil Engineering Symposium (ICES), which aims to encourage young research enthusiasts to engage in rigorous research in civil engineering. ICES includes poster presentations, 3-minute thesis talks, city planning, and paper presentations. The symposium offers young and promising students enthusiastic about research the opportunity to present their work in front of experienced professors, civil engineering leaders, and industrialists.

The team had the incredible opportunity to meet renowned academicians and industrialists and learn about various projects in the civil engineering domain. Their work was highly praised by the judges with Dr Dharmaveer, Associate Professor, Civil Engineering Dept., IIT Bombay commenting that, “I enjoyed their presentation. I like their exposure to new tools and techniques, exploring new terms, learning, and understanding, which made them worthy.”

Tanoogna from the team stated her elevation in acquiring this success. “From the outset, I was motivated to participate in the competition and showcase my skills. Our advisor, Dr Uma Maheswar was always available to answer our questions, provide feedback on our work, and offer valuable insights that helped us refine our approach. His mentorship has played an integral role in our success, and we could not have accomplished this without his assistance. We are grateful for this opportunity and the platform that IIT Bombay provided us. It has been a fantastic journey, and I look forward to participating in more competitions and pushing my limits further,” said the young scholar.

Cheritha also expressed her gratitude towards her team’s accomplishment and the valuable experience the symposium had provided. “We were able to show case our work and was able to present it effectively and secured 2nd place in the category of paper presentation. Participating in this event is an incredible experience for me to gain knowledge. I am very grateful for my advisor and my teammates Tanoogna and Venkata Reddy for their hard work towards the accomplishment of the project and for being there in difficult situations.”

Venkat also commented that the event was beneficial in gaining knowledge and to present the project. The students thanked their mentor, Dr Uma Maheswar for the opportunities he had provided and his constant encouragement to strive for excellence.

Dr Uma Maheswar, Assistant Professor, Department of Civil Engineering, SRM University-AP also voiced delight in the incredible performance of his students. “From the beginning, I had the feeling that the topic has the potential to win this competition. But this team of students has made it a reality with their excellent technical and soft skills. It was a moment of immense pride and happiness for us in the civil engineering department when our students won the contest at a prestigious platform like IITB. Heartful congratulations to Tanoogna, Cheritha, and Venkat. I wish them the best of luck in their future career endeavours.”

Abstract of the Paper

AASHTOWare Pavement Mechanistic-Empirical Design (PMED) has been introduced to overcome the limitations of the AASHTO 1993 pavement design approach in the United States. However, due to the data requirements and work involved with accurate local calibration of PMED performance models, PMED seems challenging from a benefit-cost standpoint, especially for the states with low traffic volumes and limited resources. This study aims to understand the current flexible pavement design practices in the United States and recommend an alternative design approach for a state department of transportation. The methodology included an online survey with practitioners, a literature review, and a comparative analysis of selected alternative design approaches. Two approaches were chosen as an alternative design approach based on the online survey results, interviews, and literature review. One is updating layer coefficients for AASHTO 1993, and the second is developing its mechanistic-empirical (M-E) based pavement design approach for Maine. A layered elastic analysis using winJULEA or similar combined with standard performance empirical equations was considered a proposed M-E design tool for preliminary analysis. A sensitivity analysis using the range of design input values for Maine conditions and validation with a historical project database is planned. The presentation will discuss this study’s findings and the final recommendations derived from the comparative analysis.

The Department of Civil Engineering has organised an industrial visit to Megha Engineering & Infrastructure Limited (MEIL) for engineering students to harbour them with the practical skillsets demanded by profession. The field visit was guided by senior engineers working on respective sites and co-ordinated by the faculty.
