Pavement Geotechnics Lab

Prof. Sireesh leads the Pavement Geotechnics [PAGE] Lab at IIT Hyderabad. The lab looks at geotechnical aspects of pavements, including applications of geosynthetics in pavement layers, recycling and reclaiming pavement materials, sustainable aspects of pavements, stabilization of subgrade, subbase and base layers using low energy low calcium stabilizers, drainage aspects of subbase, etc. The group is closely working with Govt. agencies and Industry partners to come up with innovative and sustainable solutions.

These are the ongoing research projects at the PAGE laboratory

Geosynthetic-reinforced Bases

Inadequate subgrade conditions, improper design and construction, and unpredicted increases in traffic demand contribute to premature pavement failures. Particularly when weak subgrades are encountered and good construction materials become scarce, pavement design becomes a challenge.

Asphalt Reinforcement

This study aims to understand the influence of different geosynthetic reinforcements on the fatigue performance of asphalt layers and the corresponding mechanisms involved. Three different types of geosynthetic reinforcement were employed to understand the fatigue behavior of asphalt layers via an asphalt beam fatigue test (ABFT) along with the use of digital image correlation (DIC) techniques.

Fly ash Geopolymer-stabilized Reclaimed Pavement Bases [FRB]

This study aims to assess the long-term performance of an alkali-activated fly ash (FA) stabilized reclaimed asphalt pavement (RAP) when utilized as a base course in a full-scale experimental test section. The test results showed that the alkali activation using the liquid alkaline activator significantly improved the mechanical strength, stiffness, and durability of the mixtures.

Geocomposite embedded GSB

Drainage is one of the primary factors considered during the design of pavements. This study presents the data from large-scale permeameter tests conducted on pavement sections to evaluate the drainage characteristics of geocomposite (GC) embedded GSB layers with and without traffic load.

Autonomous Vehicle Pavement Response

Autonomous Vehicles (AVs) have stepped up efforts to become the automobiles of the future. In terms of productivity, AVs are superior to human-driven vehicles (HVs). Current road infrastructure is believed to be unsuitable for AVs; autonomous vehicles may pose different challenges to pavement structures as they are not engineered to accommodate such novel classes of vehicles.

Behavior of Landslides

A landslide can be defined as the movement of a mass of rock, Earth, or debris down a slope. The occurrence and effects of landslides are an issue that affects the entire world and are constantly growing due to unpredictable extreme events and the exposure of people to climatic whims in the mountains. Landslides pose a threat to human life, man-made facilities, property, infrastructure, and the natural environment.

Behavior of Marine Soils

This study investigated the effect of gradation, especially of mean particle size and uniformity of gradation, on the shear modulus degradation of natural marine sands compared to regraded clean sands. A series of fixed-free resonant column tests were performed on graded clean sands and marine sands having similar uniformity coefficient values, Cu. It is observed that the modulus degradation of both clean sands and marine sands increased with the increase in Cu.

Geocell-reinforced Pavements

A series of large-scale model experiments were carried out on different geocell reinforced base courses to evaluate realistic base layer coefficients to design flexible pavements. Initially, the modulus improvement factor (MIF) for geocell-reinforced bases were establised for varying subgrade conditions. The MIF values ranged between 1.4 to 5.0 for geocell-reinforced base layers placed over different subgrade conditions.
