Civil Construction

To become more sustainable, the construction industry across the world has had to increase its efforts and identify methods to enhance recycling and material reuse. The asphalt industry has been at the forefront of these efforts, championing the circular economy (CE) with the introduction of Reclaimed Asphalt Pavement (RAP). A product of milling/removal of existing asphalt pavement, RAP is now acknowledged as an engineering material rather than a waste to be landfilled, thus providing environmental and economic benefits to road pavement design when used. Understanding RAP and Its Origins Reclaimed Asphalt Pavement is the material produced when asphalt surfaces are milled, profiled or excavated during road maintenance, rehabilitation or reconstruction work. The upper layers of a road are removed by precision profiling machines, which carefully grade the road so the material is recovered in a clean and uniform manner, free from excess contamination. Reclaimed asphalt contains aged bitum...
