Asphalt is a material that’s usually described as a sticky, black and hugely thick substance that’s comparably the semi-solid form of petroleum. The material is constructed in a plant that heats up, dries and blends aggregate, bitumen and sand into one mixture. It’s known to solidify at low temperatures and be in its liquid state under hot conditions. Many property owners opt for and roadways as the material is less expensive than concrete, easy to lay and holds great flexibility.
While bitumen may also be another name for ‘asphalt’ in some places, it’s a whole different thing. It’s the actual liquid binder that keeps asphalt together. Some roads are sealed with bitumen and then overlaid with an aggregate.
The ripple factor is the ratio between the RMS value of the AC voltage (on the input side) and the DC voltage (on the output side) of the rectifier. The formula for ripple factor is: Which can also be rearranged to equal: The ripple factor of half wave rectifier is equal to 1.21
Bitumen is actually the liquid binder that holds asphalt together. … Abitumen-sealed road has a layer ofbitumen sprayed and then covered with an aggregate. This is then repeated to give a two-coat seal.Asphalt is produced in a plant that heats, dries and mixes aggregate,bitumen and sand into a composite mix.
Lip angle is defined as the angle between end cutting edge angle (ECEA) and side rake angle. If the lip angle is more, then the strength of the cutting tool is also high i.e; lip angle is directly proportional to the strength of the cutting tool.
You doing welding in ATM temp , that mean NORMALIZING process.
Case 1
If heat input rate is High with constant speed HAZ is High
Compare to lower heat input rate
Case 2
If heat input rate is constant but speed of welding is less then optimum speed of this heat input rate HAZ is High
These conditions only HAZ can developed drastically
So it’s not depend upon welding process , it’s depends only size of weld bead , and skilled labour

You can get previous year question papers… With solved … It’s better I think so

Prepare your own notes and formula note… be strong in apptitude and resoning part

There are two reasons behind for higher HAZ
Heat input rate
Speed of welding
