What is bituminous material?
Asphalt coal tar Tar sands Brown coal
What is asphalt cement?
It's the same thing as roofing tar.
Why are the concrete slabs laid with gaps?
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.
What you mean by T16?
Tar steel of 16 mm diameter, you can find this notation in Bar Bending Schedule (BBS) and steel detailing..
What is the name of the material placed in the gaps between the concrete sections?
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.
What is the road material used on large English country estates?
tar,stone and concrete maybe granite aswell.
What is bituminous concrete?
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.
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.
How tar is useful in concrete roads?

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?
Concrete expands and contracts with temperature changes. Grooves are either cut or engineered into a concrete road/sidewalk to allow for this expansion. Without them the pavement would expand and buckle (break and heave up) and cause traffic (both auto and foot) problems. However, leaving open gaps in the concrete can accelerate the deterioration of the concrete. Cracks and breaks caused by use or water/ice invasion at the edges of slab can quickly spread and cause the road to become impassable. Tar is used to fill those gaps to cushion its use (a shock absorber for sudden changes like a big truck locking its tires right on that slab) and protect from weather erosion (tar keeps water and ice from getting down between and under the slabs). The tar needs to be pliable when its hot so that the expansion of the concrete around it has something flexible to push against rather than pushing against the next section of concrete.
Are tar driveways a good replacement for highly-cracked concrete driveways?
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.
What is sticky black road surface?
it is called tar
Why do you tar and sand a road?
You have to tar and sand a road because it allows the cars to drive more smoothly.
What often causes pothpoles in streets?
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.
What is difference between road tar and asphalt?
Road tar is made from coal. Asphalt is a heavy fraction of petroleum.
Is drive bicycle easy on tar road or rough road?
a tar road will be easier, it will be more smooth and you will be able to roll for a longer period if time
What is tar used for?
Tar is used so The road workers may fill in cracks on the road so they do not spread out more.
