Abstract

Asphalt mixture that is used for the construction of flexible pavements is mainly composed of two constituents i.e. bitumen and aggregate. Sturdy adhesion among bitumen and aggregate is the sign of durability of asphalt pavements. Adhesion is considered as one of the most important factors for sustainable asphalt pavement. This is the motive why its miles utmost important to deeply understand the phenomenon of adhesion considering the effect of alternate in temperature, moisture conditions. In this study softer binder 80/100 was selected that has less adhesion compared to hard pen grades. Limestone aggregates which is commonly used for the construction of asphalt pavements has also been selected. Two types of modifiers (Zeolite and Paraffin Wax) were selected because of the extensive use in asphalt foaming and the polymer modified asphalt mixtures as temperature reducing agent. To investigate the strength of adhesive bond, Bitumen Bond Strength (BBS) was performed at different temperatures, in dry, and wet conditions. To quantify the effect of modifiers on penetration grade and softening point conventional testing is performed. For performance grading, the PG test was performed using Dynamic Shear Rheometer. The comparisons were developed among pull of tensile strength at dry and after 72hrs water conditioning while preserving the temperature at 25 .To check the effect of temperature BBS is performed at 15 . The results illustrate that 2% zeolite shows best results in terms of adhesion and performance grade while Paraffin wax has less adhesion and poor performance grade.

Abstract

Background: Dietary adherence is a fundamental component of effective management of type 2 diabetes mellitus (T2DM). However, maintaining dietary compliance remains challenging in culturally diverse and food-centered societies such as India, where traditional dietary practices, social expectations, and family dynamics significantly influence eating behaviors. Objective: This study aimed to explore the lived experiences of adults with type 2 diabetes mellitus in India regarding adherence to dietary recommendations, with particular attention to sociocultural, behavioral, and emotional factors influencing dietary practices. Methods: A qualitative case study design with a positivist approach was employed. Fourteen adults diagnosed with T2DM were recruited through snowball sampling from three Primary Health Centers in India. Data were collected through in-depth semi-structured interviews and analyzed using thematic analysis. Strategies to ensure trustworthiness included member checking, audit trails, and data triangulation. Results: Three major themes emerged from the analysis: cultural negotiation of food choices, internalizing health literacy and self-regulation, and family roles and emotional anchors. Participants described challenges in balancing traditional dietary practices with medical recommendations, particularly during social and religious events. Individuals who were able to translate dietary knowledge into daily routines demonstrated stronger adherence behaviors. Family members played an influential role by providing emotional encouragement, assisting with meal preparation, and motivating individuals to maintain dietary discipline. Conclusion: Dietary adherence among adults with T2DM in India is shaped by complex interactions between cultural traditions, health literacy, and family dynamics. Interventions aimed at improving dietary adherence should incorporate culturally sensitive strategies and family-inclusive educational programs to support sustainable self-management.
