The method and equipment used in road construction is an important economic and design factor in road location and subsequent design. A road to be built by an operator whose only equipment is a bulldozer requires a different design than a road to be built by a contractor equipped with hydraulic excavator scrapers and bulldozer.
A 2016 study showed that in one year alone CDW recycling opportunities led to the creation of 175 000 jobs. 98 of steel in construction and demolition projects is recycled to new uses. Jobs created by recycling and reuse outnumber traditional waste disposal jobs 9to1.
The best and safe disposal methods of Nonhazardous Construction waste are 1.

Bulldozers are extremely useful for road construction where it is possible to throw the waste excavated material on the road sides. Bulldozers may only be used if the slopes at the sides are not excessively steep. However work on steep slopes can be accomplished by a bulldozer by using special techniques and expertise.
Cold InPlace Recycling (CIR) is the method whereby the existing asphalt surface is crushed and sized with the use of a road recycler machine mixed insitu compacted and then sealed with our EBS Soil Stabilizer to preserve and protect the surface from fatigue and thermal cracking raveling and pot hole formation.
This kind of cold recycling equipment usually consists of a cold milling machine a portable crusher a travelplant mixer and a laydown machine. The crushing unit crushes and screens the material that is too large from the milling machine and transfers the processed material to a mixer the recycling agent is added at this stage.
Main advantages of the cold recycling in situ • Very efficiency in comparison with conventional methods • Protection of resources additives and binding agents • Considerable reduction of CO 2 emission • Reduction of transport volume • Less exposure of the excisting road network • Reduction of dumpsite volume
Hot InPlace Recycling. Hot inplace recycling ( HIR) is a less common form of hot asphalt recycling. There are three basic HIR construction processes in use all of which involve a specialized plant in a continuous train operation ( FHWA 2001c 1 ) Heater scarification (Figure 1). This method uses a plant that heats the pavement surface
