Abstract: This study evaluates the mechanical and durability performance of High Modulus Asphalt Concrete (HMAC) modified with Polyethylene Terephthalate (PET) and Glass Fibers using a PMB 70 binder, under temperature and moisture conditions that simulate extreme Indian climates. Fiber dosages ranging from 0.0% to 0.4% by total mix weight were incorporated into Dense Bituminous Macadam (DBM) grade mixes. A series of laboratory tests, including Marshall Stability, Indirect Tensile Strength (ITS), Dynamic Modulus, and Tensile Strength Ratio (TSR), were conducted on specimens prepared at Optimum Binder Content (OBC) and varying fiber contents. Results indicate that the inclusion of 0.3% Glass Fiber improved Marshall Stability by 21.5% and reduced flow values by 14.2%, suggesting enhanced rutting resistance under high-temperature loading. PET Fiber, at 0.3%, yielded a 27.4% increase in ITS at –10°C, indicating improved resistance to low-temperature cracking. Both fiber types enhanced volumetric parameters, with Void Filled with Bitumen (VFB) exceeding 76% in all modified mixes. Moisture susceptibility improved substantially, with TSR values exceeding 85% for both fiber-reinforced mixes, signifying strong adhesion in the presence of water. The Dynamic Modulus of Glass Fiber mixes increased by 17.8% at 25°C compared to the control mix, while PET-modified mixes exhibited better modulus performance at lower frequencies. These findings suggest that Glass Fiber is more effective in improving high-temperature performance and stiffness, whereas PET Fiber excels in enhancing flexibility, crack resistance, and sustainability. The study supports the use of both fibers in region-specific applications, offering improved pavement life and reduced environmental burden.

Abstract: High Modulus Asphalt Concrete (HMAC) has gained increasing attention as a durable pavement solution for roads exposed to heavy traffic and extreme weather conditions. However, despite its high stiffness and load-bearing capacity, HMAC remains vulnerable to thermal cracking at low temperatures and rutting at high temperatures. This review paper comprehensively examines the use of synthetic fibers—specifically Glass Fiber (GF) and Polyethylene Terephthalate (PET) Fiber—to address these limitations. It explores the mechanisms by which fibers improve mechanical properties, such as tensile strength, rutting resistance, fatigue life, and moisture durability. Drawing upon a wide range of global and Indian studies, this review highlights key findings on fiber-reinforced HMAC performance under temperature and moisture extremes, discusses the environmental and structural advantages of PET fiber derived from plastic waste, and identifies knowledge gaps in current research. Special emphasis is placed on the relevance of these findings to India’s diverse climatic zones. The paper concludes by proposing future directions for research and practical implementation, particularly regarding the hybrid use of binders and fibers for sustainable and climate-resilient pavement infrastructure.

Abstract: The rise of digital currency has transformed the global financial landscape, with crypto currency emerging as a disruptive force in traditional economic systems. Over the past decade, crypto currencies such as Bit coin, Ethereum, and a range of altcoins have challenged conventional banking structures, offering decentralized, borderless, and highly secure financial transactions. This paper explores the evolving role of crypto currency in the global economy, assessing its impact on financial inclusion, regulatory challenges, monetary policy, and the future of digital finance. Crypto currency, built on block chain technology, provides a decentralized method of exchange that eliminates the need for intermediaries like banks and financial institutions. This shift has introduced benefits such as increased financial autonomy, lower transaction costs, enhanced security, and the potential to provide banking services to unbanked populations. However, it also presents risks, including volatility, regulatory uncertainty, security concerns, and its association with illicit financial activities. The adoption of digital currencies by individuals, businesses, and governments reflects the growing recognition of its potential while also raising questions about its long-term sustainability and integration into the global financial system. One of the key drivers of crypto currency adoption is the pursuit of financial inclusion. In many developing regions where traditional banking infrastructure is lacking, crypto currencies provide an alternative means of financial participation. Block chain-based transactions do not require credit histories, bank accounts, or financial intermediaries, enabling people in underserved regions to access financial services. Stable coins, which are pegged to fiat currencies, have gained particular traction as they offer stability while retaining the benefits of digital assets. Cross-border transactions, which are traditionally costly and slow due to banking restrictions, can be executed more efficiently using crypto currencies, making them an attractive solution for remittances and international trade. Despite its advantages, crypto currency remains highly volatile, with price fluctuations influenced by speculation, regulatory developments, technological advancements, and macroeconomic trends. Bitcoin, for example, has experienced extreme price swings, making it an attractive asset for speculative investors but a risky store of value. The volatility of crypto currencies raises concerns about their suitability as a stable medium of exchange and unit of account. Governments and financial institutions remain divided on how to integrate digital currencies into existing financial frameworks without disrupting monetary stability. Regulatory challenges continue to shape the future of crypto currency. Governments and central banks are actively working to establish guidelines for digital assets, balancing innovation with consumer protection and financial stability. While some countries, such as El Salvador, have embraced Bit coin as legal tender, others have imposed strict restrictions or outright bans due to concerns about money laundering, fraud, and tax evasion. The lack of standardized global regulations creates uncertainty, leading to fluctuating adoption rates and investor sentiment. In response, many nations are exploring the development of central bank digital currencies (CBDCs), which offer the efficiency of digital assets while maintaining government control over monetary policy. Institutional adoption has played a pivotal role in legitimizing crypto currency within mainstream financial markets. Major corporations, payment processors, and investment funds have integrated digital assets into their portfolios, acknowledging their potential as a hedge against inflation and an alternative investment vehicle. Financial institutions such as JPMorgan, PayPal, and Tesla have embraced crypto currency, either through direct investment, payment facilitation, or the development of block chain-based services. The emergence of decentralized finance (DeFi) platforms has further expanded crypto currency’s use cases, enabling lending, borrowing, staking, and yield farming without traditional financial intermediaries. The impact of crypto currency extends beyond financial markets, influencing sectors such as supply chain management, digital identity verification, and smart contract automation. Block chain technology provides transparency, traceability, and security, making it a valuable tool for industries seeking to improve operational efficiency. Smart contracts, self-executing agreements powered by block chain, enable automated transactions and reduce reliance on third parties, lowering costs and increasing efficiency in legal and business processes. However, security concerns persist in the digital currency ecosystem. While block chain itself is highly secure due to its decentralized nature, crypto currency exchanges, wallets, and smart contracts are vulnerable to hacking, fraud, and cyber attacks. High-profile exchange breaches and decentralized finance exploits have resulted in significant financial losses, highlighting the need for stronger security measures and regulatory oversight. Additionally, the irreversible nature of crypto currency transactions poses challenges in cases of fraud or accidental transfers, necessitating the development of user-friendly dispute resolution mechanisms. The environmental impact of crypto currency mining has also raised concerns. Bit coin and other proof-of-work (PoW) crypto currencies require substantial energy consumption for transaction validation and network security. Critics argue that this energy-intensive process contributes to carbon emissions and environmental degradation. In response, some block chain networks are transitioning to more sustainable consensus mechanisms such as proof-of-stake (PoS), which significantly reduces energy consumption while maintaining network integrity. The push for eco-friendly block chain solutions aligns with broader global efforts to promote sustainability in digital finance. As the crypto currency landscape continues to evolve, its integration into the global economy will depend on technological advancements, regulatory developments, and mainstream adoption. Governments and financial institutions must collaborate to establish clear guidelines that support innovation while mitigating risks. The potential for crypto currency to reshape global finance is undeniable, but its long-term success hinges on addressing volatility, security, regulatory concerns, and environmental sustainability. In the coming years, we may witness greater convergence between traditional finance and digital assets. The rise of central bank digital currencies (CBDCs) could coexist with decentralized crypto currencies, creating a hybrid financial system that leverages the benefits of both models. Additionally, the adoption of block chain technology in sectors beyond finance, such as healthcare, education, and governance, could further demonstrate its transformative potential. In conclusion, crypto currency represents a paradigm shift in the way we perceive and interact with money. While challenges remain, its disruptive impact on traditional financial systems cannot be ignored. Whether it ultimately serves as a mainstream medium of exchange, a speculative investment, or a decentralized financial infrastructure, its role in the global economy will continue to evolve. Stakeholders—including governments, businesses, and consumers—must navigate this rapidly changing landscape to harness its benefits while mitigating its risks. The future of digital currency is unfolding, and its implications will shape the economic and financial structures of the 21st century.

Abstract: Amid growing concerns about climate change and environmental sustainability, accurately evaluating vehicle CO₂ emissions has become increasingly important. As transportation remains a major source of greenhouse gases, there is a need for advanced, data-driven solutions to monitor and assess emission levels effectively. This project introduces a deep learning model based on Convolutional Neural Networks (CNN) to classify and rate vehicle emissions by analyzing key attributes such as fuel type, engine capacity, mileage, and emission standards. Unlike traditional rule-based or statistical methods that often struggle with complex and large datasets, CNNs excel at automatically extracting meaningful features, leading to higher prediction accuracy and adaptability. Trained on a comprehensive dataset of vehicle emission records, the model classifies vehicles into various emission categories, offering valuable insights for regulators, manufacturers, and consumers. By combining deep learning with data science, this system provides a scalable and automated method for emissions evaluation, promoting the adoption of energy-efficient vehicles and stricter environmental regulations. Furthermore, the model has the potential for real-time emission monitoring, aiding in better air quality management and supporting the shift toward greener transportation technologies.

Abstract: Art and cultural hubs have emerged as powerful instruments in reshaping urban identities and fostering community engagement. This study explores the role of such spaces in promoting inclusivity while catalyzing urban regeneration. As cities grapple with socio-economic disparities, cultural fragmentation, and deteriorating public spaces, art and cultural centers offer dynamic platforms for interaction, expression, and innovation. These hubs serve not only as venues for creative expression but also as vital nodes that bridge diverse communities, stimulate local economies, and rejuvenate underutilized urban fabric. Through a multidisciplinary lens combining urban design, social theory, and cultural policy, this paper investigates how thoughtfully designed art and cultural hubs can facilitate inclusivity—physically, socially, and economically. It also examines global and local case studies that highlight successful regeneration projects driven by cultural infrastructure. Emphasis is placed on accessibility, participatory design processes, adaptive reuse of heritage structures, and integration with public space networks. The study concludes that inclusive design in cultural hubs—rooted in context, community, and climate—can transform marginalized urban areas into vibrant, equitable, and resilient neighborhoods, ultimately reinforcing a city’s cultural capital and collective identity.

Abstract: The adoption of Warm Mix Asphalt (WMA) offers a sustainable alternative to conventional Hot Mix Asphalt (HMA), especially in developing countries like India where energy efficiency and cost-effectiveness are critical. This study investigates a simplified method of producing WMA using a medium-setting bitumen emulsion and VG 30 binder for Dense Bituminous Macadam (DBM) mixes. Marshall samples were prepared at three different mixing temperatures—110°C, 120°C, and 130°C—with varying bitumen-to-emulsion (B:E) ratios ranging from 50:50 to 100:0. Marshall Stability, flow value, unit weight, air voids, voids in mineral aggregate (VMA), and voids filled with bitumen (VFB) were evaluated to determine the optimum binder content (OBC). The results revealed that a B:E ratio of 70:30 at 120°C provided the highest Marshall Stability value of 11.6 kN with acceptable volumetric parameters, demonstrating the optimal balance between strength and workability. The study confirms that emulsion-based WMA can deliver comparable mechanical properties to HMA while enabling lower production temperatures, making it suitable for Indian climatic and economic conditions.
