The main difference between Asphalt and Macadam is that the Asphalt is a sticky, black and highly viscous liquid or semi-solid form of petroleum; bitumen variety and Macadam is a type of road construction pioneered by Scottish engineer John Loudon McAdam. The word is derived from the Ancient Greek ἄσφαλτος ásphaltos.

What is the opposite of bomb?

A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Other military explosive weapons not classified as “bombs” include shells, depth charges (used in water), or land mines.

other words for atomic bomb atom bomb. hydrogen bomb. neutron bomb. nuclear warhead. A-bomb.

: macadamized roadway or pavement especially with a bituminous binder.

This is because macadam is simply another name for asphalt. The term ‘Macadam’ can be traced back to the history of the inventor, John Loudon McAdam. Therefore, people in construction and the asphalt industry may use these terms interchangeably when they are talking about this type of pavement materials.

macadam in British English (məˈkædəm ) a road surface made of compressed layers of small broken stones, esp one that is bound together with tar or asphalt.

Classification of Roads and their Details [PDF]

• Earthen Roads.
• Gravel Roads.
• Murrum Roads.
• Kankar Roads.
• WBM Roads.
• Bituminous Roads.
• Concrete Roads.
• National Highways.

While macadam roads have now been resurfaced in most developed countries, some are preserved along stretches of roads such as the United States’ National Road.

Bituminous concrete:- aggregates mixed with binder(bituminous) and poured in area of construction, simply just like concrete mixing and placing. Bituminous macadam:- aggregates of two to three layer in decreasing sizes placed and compacted, afterwards bituminous binder is sprayed and again compacted. 10K views.

Bituminous Macadam (BM) This is a recipe type mix produced that gain no kind of quality in terms of strength and volumetric. The void content is 20 to 25% higher than the dense graded bitumen (DBM). The DBM have a void content of 3 to 5%. The BM have high potential to attract water and moisture.

Definition of bitumen penetration grade 60/70 Bitumen penetration grade 60/70 means the penetration value is in the range 60 to 70 at standard test conditions which commonly used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road construction.

They are:

• Hardest Bitumen Grade 40 –50.
• 60 –70.
• 85-100.
• 120-150.
• Softest Bitumen Grade 200-300.

The Difference between Bitumen 60/70 and 80/100 The main difference between 60/70 and 80/100 is their penetration value. To decide between 60/70 vs bitumen 80/100, we should consider the fact that bitumen penetration 80/100 is softer than bitumen 60/70. For this reason, bitumen 80/100 is used at cold temperatures.
