Road As a General Transportation Means

Roads are road transport infrastructures covering all parts of the road, including auxiliary buildings and equipment destined for traffic, located on the soil surface, above ground level, below ground and/or water, and above the water surface, except railroad fire, lane road, and cable road. Public roads are roads dedicated to general traffic. A special road is a road built by instant, a business entity. Individuals, or community groups for their own sake. The toll road is a public road that is part of the road network system and as a national road whose users are required to pay the toll. The toll is a certain amount of money paid for toll road usage. The highway is a public road for continuous traffic with full access control and without comparable intersections and equipped with a street fence. Road construction is the process of opening a traffic room that overcomes various geographic barriers. This process involves diversion of the earth the construction of bridges and tunnels, even the transfer of vegetation. (This may involve forest clearance). Various types of road builders will be used for this process. In the process of making the road itself called the paved road. Usually, when you are hardening the road, you need a tool to evaluate and design hardening components with sub-base and the base course which are also used as power parameters. Here we are familiar with the cbr testing guide designed to consider the variations caused by the water content.

Pavement is a mixture of aggregates and bonding materials used to serve the traffic load. Aggregates commonly used in road pavement are crushed stone, stone, stone and steel by-product. While the materials used include cement, asphalt, and clay. The earth surface must be tested to see its ability to accommodate vehicle loads. Next, if necessary, the soft soil will be replaced by a harder land. This layer of soil will become the base layer. Next, up over this base layer will be coated with one more layer called the surface layer. Usually, the surface layer is made with asphalt or cement. Water drainage/drainage is one of the factors that must be taken into account in road construction. Water gathered on the road surface after rain not only endangers road users, will instead erode and damage the road structure. Therefore the road surface is not really flat, on the contrary, has a slope that leads to the ditch on the roadside. Thus, the rainwater will flow back into the gutter.
