Objectives: To develop an optimum bituminous mix by studying the properties of construction demolition waste aggregate (CDWA) and plastic as a partial replacement natural coarse bitumen. The performance strength conventional modified were studied using marshall stability test. Methods: Construction is produced crushing screening old concrete from waste, which then used for aggregates in pavemen...

Glass is widely used in our lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling. The use of recycled glass helps in energy saving. The increasing awareness of glass recycling speeds up inspections on the use of waste glass with different forms in various fields. One of its significant contributions is to the co...

The construction of waste incinerators in populated areas always causes substantial public concern. Since the heat from waste combustion can be recovered to power district heating networks and allows for the switch-off of domestic boilers in urbanized areas, predictive models for health assessment should also take into account the potential benefits of abating an important source of diffuse emi...

This paper presents for the first time the results of a full life cycle assessment (LCA)1 study for the three most common types of house in the UK: detached, semi-detached and terraced. All life cycle stages are considered, including house construction, use and demolition after 50 years. The results indicate that the use stage has the largest contribution to most environmental impacts. For exam...

Environmental problems have attracted worldwide attention, and the recognition of their importance has risen through the newspapers and other media every day. In the construction industry, industrial waste resulting from civil engineering work has become a big problem, termed construction pollution. Construction sludge and muddy water resulting from construction or demolition are particularly d...

Natural radioactivity is the main source of radiation which affects the human body [1]. Anthropogenic activities (e.g. high-altitude fl ights, mining and living in buildings) have increased the exposure to these sources [2]. In particular, the problem of natural radioactivity in buildings is of great interest since the building materials are of terrestrial origin and they consequently contain s...
