What is modified bitumen?
Modified Bitumen it makes bitumen more power while you use it in construction area , Modified Bitumen Introduced in Eighties to combat with common pavement distress. There are about 4 different specifications based on type of modifier used similar to ASTM specifications for modified bitumen. Many Authorities advises for use of minimum 10% modified Bitumen
What is a mixture of clay and sand with bitumen could replace petroleum one day?
The mixture of clay, sand, and bitumen that you mention is normally known as tar sand, and there are large deposits of it in the Canadian province of Alberta, as well as a few other locations. The bitumen can be extracted from the mixture and can then be refined into petroleum products such as gasoline, etc. This is more expensive than using oil from oil wells, however, in a world of very high and ever increasing oil prices, the exploitation of tar sands has become economically viable.

What is the difference between oil rectified bitumen and oxidised bitumen?
Bitumen whose rhelogical properties have been modified by reaction with air at elevated temperatures. This material is referred to as blown bitumen Oxidised while Air rectified bitumens are used in paving applications as well as roofing applications for some industrial applications.For more info: http://www.roadstarbitumen.com
How do you get soft bitumen to set at room temperature?
Bitumen is not reactive in the sense that it sets. Furthermore, it's strongly temperature sensitive ie the apperance will depend on temperature. This is perhaps one of the main properties of bitumen, along with stickiness. If its fluid (or thick) n room temperature it will stay that way. There are slow processes, chemical and physical, that will affect properties but these are slow and long term. If you want it to set, lower the temperature or choose another quality of bitumen. There are bitumens that more or less brittle at room temperature.
What is low grade copper ore and what are the problems associated with it?
Low-grade copper ore contains a small amount of copper (1% or lower) and a big amount of waste rock. The problem with low-grade copper is that it breaks down and melts more easily than copper ore.
