of land In this study use of Aggregate as a filler material bituminous concrete and waste plastic as coating material Find its utility in bituminous mixes for road construction Improvement in properties of bituminous mix provides the solution for disposal in a useful way OJE TIVES Study has been carried out to satisfy following
Bituminous Treated Aggregate Base Bituminous treated aggregate base is one type of cold mix Asphalt Concrete It can consist of processing gravels; crushed stones; or blends of gravel sand and crushed stone materials — each stabilized with a specified percentage of asphalt Job mix formulas mentioned in Chapter 3 are not required
The use of RAP as recycled aggregate for concrete is a promising route but a complete characterization is needed to ensure concrete performance and durability Graphical abstract The interface between natural aggregate and bituminous layer appears continuous and smooth as observed elsewhere [65] Download Download high res image 535KB
By utilization of altered bitumen mix concrete along with the expansion of processed waste plastic of around 5 10% by wt of bitumen the fatigue life quality and other properties of solid bituminous blend which ultimately enhances the life span and performance of the flexible pavement with minor reduction in the amount of bitumen use
Over the years we have seen the increase in the use of recycled asphalt in asphalt mixtures The following article shows the review work through database search performed on the literature concerning the use of that type of asphalt as it produces a great economic and ecological advantage Nevertheless it could mostly be found that its use in
relative measure of aggregate to impact which has a different effect than the resistance to gradually increasing compressive stress The aggregate impact value should not normally exceed 30% for aggregate to be used n wearing course of the pavements The maximum permissible value is 35% for bituminous macadam and 40%
This review is centered on the use of waste plastics as an additive for road construction This review discusses extensively the state of the art methods that can be employed in achieving a waste
The term bituminous materials commonly include all materials constituted by aggregate bound with either bitumen or tar the latter term being used as a binder material before the era of bitumen Bituminous materials are used almost exclusively in road construction Fig although bitumen meets industrial applications and other forms of construction such as
A bituminous mixture is composed of approximately 95% by weight or 80% by volume mineral aggregate Therefore it is important to see how aggregate gradation affects the performance of bituminous
The materials used in flexible pavements are comprised in weight of more than 95% natural origin aggregates NA Arabani and Azarhoosh 2012 The manufacturing of hot mix asphalts HMA requires large volumes of NA aggregates are comprised in weight in 90% 95% or 80% 90% in volume Khasawneh and Alsheyab 2020; Tahmoorian and Samali 2018
As building construction speeds up demolitions will increase due to concrete s limited lifespan ultimately ending in demolition In earthquake prone countries like Nepal buildings may collapse during earthquakes leading to the disposal of bricks creating potential environmental pollution This research explores the use of Crushed Brick Aggregate CBA
In the present study an effort has been made to utilise recycled concrete aggregate RCA as a replacement for the traditional coarse fraction in paving mixtures for addressing the issue of dumping space Additionally waste materials such as fly ash FA and rice husk ash RHA were utilized as fillers in bituminous mixtures The research aimed to
This research is intended to contribute toward the understanding development and implementation of a more fundamental design process for bituminous pavement materials utilizing thermodynamic properties of the materials involved The theory developed by van Oss Chaudhury and Good forms the basis of this research Optimization of techniques to
Globally the unabated extraction of natural resources without recourse to a circular economy has wreaked havoc on the environment As a result natural resources are depleted resulting in increased pollution and solid waste generation endangering biodiversity and ultimately contributing to global warming Zhong and Wu 2015 For example due to global

of recycled waste material is one tonne less of new aggregate and/or bituminous binder required to be produced from finite natural resources as well as one tonne less material that might
The global aggregate production of 40 billion tons Fig 1 is an indication of the vast development projects which are materializing around the world [1] As the land for landfill becomes scarce and the world demand of aggregate reaches to an enormous 40 billion tons annually ways to use C&D waste is gaining importance due to legislation it is cheaper and
