[engineering] THE IMPORTANCE OF MEDIAN/TROTOAR ON THE ROADS
There is bound to be a frequent view of the median of roads in urban or cross-city roads. the function of the median is to separate 2 traffic lanes. We certainly find many urban roads with road dividers that use the median.
There are many benefits of the road median. the first separates the two traffic flows in opposite directions and makes the driver more comfortable on the road. the existence of a median in the middle of the road can also reduce traffic accidents.
decorating the road median that has been installed in the middle of the road makes the road more beautiful and makes the driver relax. To make sidewalks on the road median, precast concrete will usually be attached which can be directly attached to the road median.
In road construction, a lot of additions are needed on the road section. construction of median drainage and sidewalks, dividing line road markings and other road signs. for setting red lights and also a place to turn directions on the road, it is very much needed on urban roads and inter-provincial roads.
how to install sidewalks using precast concrete that is ready to be attached to the median of the road. The size of the concrete that is installed is usually 20cm wide, 30cm high and 50cm long. The concrete will be installed along the road which has a middle median. the function of the concrete installation as a sidewalk.
when all the installation has been completed, in the middle of the sidewalk will be heaped using the ground. after the soil is solid on the sidewalk, flowers or other greening will be planted. some have made flower pots for some flowers to beautify the sidewalk.
Road signs are needed on the highway, if there are no road signs and signs it will be difficult for drivers to know a direction where. Road signs will usually be painted on the road body to limit where vehicles can drive at certain signs.
In order for the road to remain durable, the role of the channel is needed to drain water on the road in case of rain. the road is built with a slope of 6% from the road body so that water will flow to the side of the road. Therefore, beside the road it is very well arranged to drain the water flowing from the road into the channel.
roads that do not have drains or drains are particularly vulnerable to damage. especially if the road is submerged with water for more than 24 hours. it is very dangerous to damage the asphalt road surface. while road asphalt has a density level of 100%. if the asphalt has holes and cracks the water will very easily enter and make the road very easily damaged.
