Analysis of Alkali Activated Concrete Pavement Using Kenpave Software for Low Volume Roads

In the present study, an attempt was made to analyze the concrete pavement developed using alkali activated concrete (AAC) mixes. Finite element method (FEM)-based software package called KENSLAB (constituent of KENPAVE software) has been used for this study. In the study, the pavements were modeled for single wheel load applications and standard wheel load applications, obtained as per the IRC standards. The combined wheel load and temperature flexural stresses at interior, edge, and corner region were analyzed and the obtained results were compared with the models of various trial thicknesses ranging from 150 to 400 mm. The results indicate that for all the loading positions, as the thickness of the concrete increases, the combined temperature and wheel load flexural stress decreases. The values are in the range of 1.0–4.75 MPa for the wheel load application; and the range of 0.795–7.05 MPa for standard axle load applications. Most of the values are less than the 28 day flexural strength of the reference and optimum AAC mixes, making it suitable for pavement applications.
