Crushed brick blends with crushed rock for pavement systems

Abstract

Construction and demolition materials account for a major proportion of the waste materials present in landfills in Australia. Crushed brick and crushed rock are, however, viable substitute materials for natural resources used as construction materials in engineering applications. Crushed brick is one of the major components of demolition materials. The crushed rock used in this study originates from ‘basalt floaters’ or surface excavation rock (basalt), which commonly occurs near the surface to the north and west of Melbourne, Australia. The engineering characteristics of various proportions of crushed brick blends with crushed rock obtained from extensive laboratory testing are presented in this paper. The engineering properties obtained were compared with existing local road authority specifications for pavement sub-base or light-duty base material and backfill material for drainage systems to ascertain the potential use of crushed brick blends. The materials for the experimental works were collected from a recycling facility in Victoria, Australia.

Evaluation of Interface Shear Strength Properties of Geogrid-Reinforced Construction and Demolition Materials Using a Modified Large-Scale Direct Shear Testing Apparatus

“…Recycling of C&D waste materials into sustainable civil engineering applications is of global importance, as we seek new ways to conserve our natural resources as well as reduce reusable waste materials from being landfilled (Aatheesan et al 2010;Hoyos et al 2011;Arulrajah et al 2013b;Rahman et al 2013). C&D aggregates have recently been found to be viable alternative materials in civil engineering applications such as pavements, footpaths and other road construction applications.…”

Study of Using the Crushed Clay Bricks With Natural Aggregate as Unbound Subbase Pavement Layer in Segregated Form

“…Construction and demolition of buildings and structures are producing excess or waste material which is including concrete, brick, steel, and other building materials and products [1], the recycling and reuse of industrial wastes should be considered in geotechnical and pavement applications in order to generate sustainable solutions [2], [3]. The replacement of traditional gravel materials with alternative materials is increasingly preferred from both environmental and economic perspectives [4].…”

Effect of Geogrids on Interface Shear Strength Properties of Recycled Crushed Brick

“…This includes C&D aggregates such as recycled concrete aggregate (Azam and Cameron, 2013;Arulrajah et al 2013a), crushed brick (Aatheesan et al 2010;Arulrajah 2012a), reclaimed asphalt pavement materials (Puppala et al 2011;Arulrajah et al 2013b). Other waste materials that have generated recent interests in various geotechnical applications include waste rock (Arulrajah et al 2012b), waste glass (Ali et al 2011;Disfani et al 2011;Disfani et al 2012;Imteaz et al 2012;Arulrajah et al 2013c) and fly ash Rahman et al 2011;Horpibulsuk et al 2012;Sukmak et al 2013).…”
