What type of rock if you are driving along a highway cut through walls of rocks made of layers?

If you are driving along a highway and see walls of rock made of layers, you are likely observing sedimentary rock. Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles over time, resulting in distinct layers or strata. Common examples include limestone, sandstone, and shale. These layered formations can often be seen in road cuts and cliffs.


When compacting road base how thick should the layers of material be to obtain proper compaction?

Most aggregate material compacts to 90% for a road base, losing from 18 - 27% of its initial (loose) volume. So, in terms of thickness, count on having the initial spread of the material being about 25% thicker than you want the final compacted thickness to be. However, this may depend on the particular aggregate you are putting down. Your supplier may be able to supply you with more accurate information, and should have good experience in this area related to their product(s).


Describe about the layers of bituminious road?

A bituminous road typically consists of multiple layers. The top layer is the wearing course, which provides smoothness and skid resistance. Beneath it is the binder course, which provides structural support and helps distribute loads. The base course is the foundation layer that bears the traffic load and provides overall strength to the road.


What landforms are along the silk road?

Some of the landforms along the Silk Road include deserts (such as the Gobi Desert), mountain ranges (such as the Pamir Mountains and Tian Shan), and plateaus (such as the Tibetan Plateau). Rivers like the Yellow River and the Tigris and Euphrates are also significant features along the Silk Road.


What is the stone and tar mixture which is used on road surface?

The mixture of stone and tar used on road surfaces is called asphalt. It is a durable and cost-effective material that provides a smooth driving surface and helps to protect the underlying layers of the road.
