It's the same thing as roofing tar.
Concrete expands when heated and contracts when cooled. Roads are built with gaps filled in with rubber, tar or other flexible mass which will not wash away when it rains. This prevents them from cracking into pieces as they contract in winter and prevents and buckling when it is hot in summer and the slabs expand. Bridges have gaps, usually a set of metal 'teeth' to prevent them from crushing themselves. If the gap is at vertical columns it is because the slab must be isolated from the columns so that when the building moves it will not crack the slab. The boxes (or diamonds) are lined around the perimeter of the opening with 1/2" expansion material and around the column to all movement (including the expansion and contraction of the slab itself). There are reasons to leave other holes such as for future plumbing work etc.
Tar steel of 16 mm diameter, you can find this notation in Bar Bending Schedule (BBS) and steel detailing..
Cementanswer #2The material is an asphalt impregnated fiber material designed to block and penetration of water and be somewhat flexible. During the lifetime of the roadway the maintenance efforts will often fill the gaps with a liquid tar based sealant to keep water out and prevent the creation of potholes. Water gets through and washes out the supporting structures which causes cracking. Water and ice are the enemies that cause potholes and other problems.
tar,stone and concrete maybe granite aswell.
A bituminous road is a road that has been covered with bitumen. If this is wrong, could I please have the correct answer. A bitumen road is different from tar road. bitumen is extracted from crude oil. since the bitumen is used as a binder this road is called bituminous road. if tar is used as a binder then it is called tar road.
Because the concrete will expand and the tar will become soft. So the concrete has room to expand. With out cracking.

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.
A tar and chip drive way is the best alternative to a concrete drive way. They are the most similar, look great, and require much less maintenance. Tar and chip drive ways actually give your car better traction as well, so it may provide better for you in the winter months.
it is called tar
You have to tar and sand a road because it allows the cars to drive more smoothly.
Potholes are holes created in the road due to various stresses. On tar roads, the tar can expand and contract considerably during the summer and the winter. As a result of this constant contraction and expansion, parts of the road can erode away. During the winter, ice can also form in the pores in the tar road and the freezing of the ice expands the road slightly. Over days, weeks, and months of exposure to such stresses, tar roads break away at weak points and form potholes. Continued driving and application of the weight of multiple cars and trucks can also facilitate the road's destruction. The same can occur on concrete roads, although not as often as on tar roads.
Road tar is made from coal. Asphalt is a heavy fraction of petroleum.
a tar road will be easier, it will be more smooth and you will be able to roll for a longer period if time
Tar is used so The road workers may fill in cracks on the road so they do not spread out more.
