Shafkat Alam-Khan to present on Innovative Gravel Loss Prediction Model at the International Conference on Low Volume Roads
Come see Shafkat speak at the International Conference on Low Volume Roads
APTech Engineering Associate Shafkat Alam-Khan will be sharing his recent research on gravel loss prediction models at the International Conference on Low Volume Roads. The event, scheduled from July 23 to July 26 in Cedar Rapids, Iowa, brings together industry experts and professionals to exchange knowledge and explore advancement in road infrastructure.
About the presentation
Shafkat’s presentation, titled “A Gravel Loss Prediction Model Using Beta Regression,” aims to revolutionize the maintenance practices of unpaved roads. These roads—which form a significant portion of transportation networks in many countries—play a vital role in economic development and agricultural productivity of rural and remote communities. Understanding the impacts of resurfacing treatments on these roads’ performance is crucial for effective budget scheduling and decision-making.
Existing gravel loss prediction models
The presentation will begin with an overview of three popular gravel loss prediction models: Highway Development and Management Model 4, South African Technical Recommendation for Highways Model 20, and Australian Road Research Board Model. Shafkat critically evaluates the practicality and reliability of these existing models and identifies their limitations.
A new model with BR analysis methodology
Shafkat will also speak about how researchers used a beta regression (BR) analysis methodology to develop and calibrate a gravel loss prediction model specifically for Iowa roadways. During this portion of the presentation, Shafkat will explain how the BR model outperformed the existing models in terms of simplicity and effectiveness, offering a practical approach to quantify annual roadway gravel loss. With Shafkat offering insights into resurfacing frequency and maintenance requirements, he will show how this model has the potential to optimize the lifespan and performance of unpaved roads.
Additional APTech staff will be present
In addition to Shafkat, Local Municipalities and Private Agencies Director Mark Gardner, P.E. will be in attendance. The insights he will gain from this 4-day conference will afford him integral information that will benefit our clients.
