Why are concrete highways made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
Why concrete highways are made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
The gaps between the concrete sections are filled with tar The tar becomes soft when it is warm. Why is it important that the tar is soft?
It is important that the tar is soft because it allows for expansion and contraction of the concrete sections due to temperature changes. If the tar were hard, it could crack or break when the concrete expands, leading to potential structural issues. The soft tar provides flexibility and helps prevent damage to the concrete surface.
Is tar road better than concrete road?
it smells better
Why are there channels filled with tar at intervals across cement-concrete roads?
Where cracks form in the asphalt/concrete, repair crews fill the cracks with tar to keep water from seeping in and widening the cracks into pot holes.
What is the road material used on large English country estates?

Is tar useful in concrete roads?
Because the concrete will expand and the tar will become soft. So the concrete has room to expand. With out cracking.

Concrete roads why do they have gaps?
concrete compared to human strength is very strong but with so many cars,bikes,people ect. it can easily crack to stop this happening they but black tar under and on the sides so its is stronger and less likely to crack.
Why concrete roads are laid in section with pitch between them?
Concrete, whether in a road or a building expands (gets longer) in hot weather and contracts (gets shorter) in cold weather. So the builders install an expansion strip every so many feet to allow the concrete to make these small but significant changes in length. If this were not done, the concrete, when warm, would expand, and having nowhere to go, would go up (roads) or out (buildings), thus ruining the road or building. These expansion joints are filled with pitch, tar, or mastic - they call it different things in different parts of the country - to keep out water. Water would freeze, and cause the same problems.
What is bituminous concrete?
Bituminous concrete is a type of pavement material that consists of asphalt or bitumen mixed with aggregates like crushed stone, gravel, or sand. It is commonly used for road construction because it provides a smooth and durable surface that can withstand heavy traffic loads. Bituminous concrete is also known for its flexibility, making it resistant to cracking and weathering.
What is in tar?
tar is filled with wonderful chemicals like bunny rabbits and lovely deer
