The price of raw polymers used for making most of the waste plastics has confined the implementation of polymer modified bitumen (PMB) only to the major road projects. In view of the same, an attempt to make a PMB by such wastes was considered as a 'state-of-art' in this investigation. Therefore, the different proportions of waste plastic fractions were blended with the pristine bitumen and the resulting blend characterized by thermal kinetics analysis, microstructural analysis, and Marshall mix design, respectively. The major findings have predicted the highest thermal stability of the blend was achieved by mixing plastic bags, plastic milk pouches, and plastic cups together in proportion of 2:0.25:1 to virgin bitumen with no thermal decomposition. Further, uniform dispersion of 'bee-like structure' in that blend has reflected its homogeneity. Besides, such modified bitumen has elevated the Marshall quotient of the bituminous mix by 16%, which can preferentially be used in the rural roads safely, confirmed by Marshall mix design. Key words: mixed plastic modified bitumen, activation energy, atomic force microscopic (AFM), Marshall mix design. Le prix eleve des polymeres bruts utilises pour la fabrication du bitume modifie par polymeres (BMP) a limite sa mise en oeuvre uniquement pour les grands projets routiers; cependant la plupart des dechets plastiques peuvent etre utilises pour la fabrication du BMP. Compte tenu de ce qui precede, une tentative de fabrication d'un BMP au moyen de tels dechets a ete consideree comme << fabrication de pointe >> dans la presente etude. Par consequent, les differentes proportions de fractions de dechets plastiques ont ete melangees au bitume vierge et le melange a ete caracterise par l'analyse cinetique thermique, l'analyse microstructurale et la conception du melange Marshall. Les principaux resultats ont devoile que la stabilite thermique la plus elevee du melange a ete atteinte lorsque le melange de sacs en plastique, de sachets de lait en plastique et de gobelets en plastique etait en proportion de 2:0,25:1 au bitume vierge sans decomposition thermique. De plus, la dispersion uniforme de la << structure ressemblant a des abeilles >> dans ce melange a reflete son homogeneite. En outre, ce bitume modifie a eleve le quotient Marshall du melange bitumineux de 16 %, qui est de preference utilise en toute securite sur les routes rurales, comme le confirme la conception du melange Marshall.

The Agricultural Internet of Things (AIOT) transforms food production by integrating IoT and IFTTT services in farming. Devices gather data on temperature, humidity, soil quality, and pests, enhancing monitoring accuracy. However, web services like IFTTT pose security risks, challenging agricultural operations’ integrity. A new study proposes a robust three-way authentication method for smart agriculture systems, rigorously evaluated using ROR model, BAN logic, and AVISPA tool. Computational tests with MIRACL Cryptographic SDK confirm efficiency. This research builds on previous work, ensuring AIOT-based farming’s security and integrity. Comparative analysis shows the proposed scheme’s computational efficiency, lower storage needs, and enhanced security over existing approaches. [ABSTRACT FROM AUTHOR]
