Utilization of Waste Polyethylene Terephthalate with Bitumen for Road Construction
Abstract: Polyethylene terephthalate (PET) is commonly used for soft drink water bottles and other applications. However, disposal of this waste PET in large quantities causes environmental problem, as it is considered non-biodegradable material. This study investigated utilization of waste PET mixed with 60/70 penetration grade of bitumen to be as a raw material for road construction. The effect of temperature (140, 150, 160°C), composition of PET (4, 8, 12%) and mixing …

Performance Evaluation of Rubber Crumb-Modified Bitumen for Sustainable Pavement Applications
Abstract: This research investigates the effect of rubber crumb modification on the physical and mechanical properties of VG-40 bitumen for flexible pavement applications. Rubber crumbs were incorporated at varying percentages (0, 8, 10, 12, 14, and 16%) to analyze their impact on penetration, softening point, ductility, and elastic recovery. Additionally, the Marshall stability test was conducted to evaluate the strength and deformation characteristics of the bitumen mix. The results demonstrated a …

Comparison of High and Low Temperature Properties of Dual Modified Asphalt Binders with Polyphosphoric Acid and Polymer Modified Bitumen using Rheological Tests
Abstract: The main objective of this study was to investigate the properties of asphalt binder mixtures at both high and low temperatures. To achieve this, two types of admixtures were selected and combined, resulting in a technology known as dual modified asphalt binders. Extreme temperatures during summer and winter can lead to significant issues such as cracking and rutting in asphalt binder pavement. In order to address these problems, a comprehensive …

Strength and Durability Characteristics of Fiber Modified Asphaltic Bitumen
Abstract: Flexible pavements with bituminous surfacing are widely used in India. Exponential increase in traffic, overloading of commercial vehicles and significant variations in daily and seasonal temperatures have shown some limitations of conventional bitumen performance. Earlydevelopments of distress symptoms like cracking, rutting, raveling, undulations, shoving and potholing of bituminous surfacing have been reported for flexible pavements. Toenhance the properties of road, bitumen is modified by the addition of some waste materials. …

Study The Effect of Metakaolin Powder in Hot Mix Asphalt as Mineral Filler
Abstract: Mineral fillers are crucial for bridging the spaces between the internal particles of the asphalt matrix. The purpose of this study is to investigate the mechanical properties of hot mix asphalt as well as the impact of utilising Metakaolin (MK) as a mineral filler. Coarse aggregate, fine aggregate, and filler are the main components of hot mix asphalt (HM). With or without modifiers, materials and asphalt binders. HMA components have …

Studies on Polymer Modified Bitumen with various Fiber Impregnation
Abstract: Transportation sector is showing immense growth in the recent decades, modern vehicles introduced require a more stable platform to run better. In terms of road construction, we are not yet reaching the modernized standards adopted by other countries and usage of modern and innovative road construction materials are yet to be used in transportation infrastructure sector. The available roads are also getting damaged due to improper maintenance of top layer …
