Is black asphalt strips placed between section of concrete to allow for the expansion and contraction of the concrete?

Partially. The asphalt strips are placed between sections of concrete to make up for the expansion and contraction of the earth around the concrete. Because with the changing seasons (mostly summer and winter because their temperatures vary so much from other seasons) the earth "dirt" expands and contracts; such is the same as when you put a glass of water into the freezer, it will look like there is less ice afterward than the amount of water that you put into it because the atoms contract together to make a solid. Also the same as when it is cold out, you can move your body less than you can when it's warmer out.

What is asphalt concrete type 1 surface course and asphalt concrete type 2 intermediate course and asphalt concrete base and tack coating between courses?
can we use polypropline fibre in concrete
Why should large concrete slabs be laid with expansion so that they are not touching?
because large slabs of concrete have expansion joints between them.
Why are pieces of rubber placed between slabs of concrete?
Concrete expands and contracts depending on the temperature. The strips are called expansion joints.
What are the effects of expansion and contraction in the design of bridges pavements and MRT lines?
- MRT and Railway tracksif a continuous track of metal is used, it will expand in hot weather and bent. trains running on bent tracks may be derailed. to prevent this, railway tracks are laid in sections with expansion gaps between them. A sliding joint between adjoining rails allows them to expand without bending.- bridgesboth concrete and steel bridges are built with allowance for expansion and contraction due to changes in the surrounding temperatures. Rollers and sliding joints allow for the movements of the bridges as it expands and contracts
What is the difference between asphalt and concrete?
"Asphalt" the paving material is more properly called asphaltic concrete. It's gravel held together by a binder of a tarry substance extracted from crude oil known as bitumen. Bitumen is also itself sometimes called asphalt. "Concrete" is a type of building material that basically consists of rocks (gravel) combined with cement and usually sand. the crisp like the firt jsk; <:O :) >:l
Why do roads have the gaps between the large pieces of concrete?
They are expansion gaps that allow for the expansion and contraction of the concrete.

What is the difference between contraction and expansion?
In contraction the size of item becomes smaller. In contract, expansion increases it.
The difference between contraction joint and construction joint?
A construction joint in concrete jobs is a joint where a fully set and hard concrete joins a fresh concrete to make a joint. Normally, cracks would occur at this joint because concrete was not cast monolithic. A contraction joint is joint between two concrete edges so formed which allows minute movement between the two edges caused by heat or some other external forces. Usually, contraction joints are also referred to as expansion joints.
Why there are spaces between bridges?
To allow for expansion and contraction.
Why are the gaps between adjoining rails?
To allow for expansion and contraction.
Why should large concrete slabs be laid with expansion so that they are not touching?
because large slabs of concrete have expansion joints between them.
What is the best surface for a basketball court between asphalt concrete grass wood and why?
asphalt has the best bounce and it doesnt make much noise
What do you put between slabs after laying them?
in between existing concrete and the new concrete you need to place an expansion joint in between the two.
When a concrete road is put down black asphalt stripes are placed between sections of the concrete to?
Prevent or reduce cracking of the concrete due to thermal expansion. Most materials expand when heated and contract when cooled. The strips are usually a fibrous material that allows the concrete expand and contract without breaking. Without those strips, random and irregular cracks would occur.
Concerned about the gap between the concrete edge or trim of pool and the rest of the concrete flooring?
I assume the "gap" you refer to is the expansion joint between the coping and the concrete deck. The expansion joint is there to prevent damage from occurring in case of movement. There should be no reason for concern, unless you are replacing the deck.
What is the property of matter where it changes volume when it changes temperature?
The property of solids in which they enlarge when warmed is thermal expansion. The opposite, shrinking when cooled, is thermal contraction. This property greatly effects how bridges, sidewalks, and concrete roads are made. They all have "expansion gaps," gaps between sections that allow the sections to expand in the heat of summer. Without those, the concrete would break and the bridges would warp and bend.
