Rubblization is a proven construction technique that turns a deteriorated concrete road into the base for a smooth, safe, quiet, durable pavement constructed of Hot Mix Asphalt (HMA) It minimizes delays for motorists and allows for construction during "off-peak" hours
Macadam is a type of road construction, pioneered by Scottish engineer John Loudon McAdam around 1820, in which single-sized crushed stone layers of small angular stones are placed in shallow lifts and compacted thoroughly A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a binder to keep dust and stones together
Nov 21, 2018· The basic construction process for building a road is similar for any road The differences arise in the finishing of the road or the surface materials used to finish a road The process begins with road design, including surveying the route, allowing for drainage and considering the expected volume of traffic and planned development in the area
