Ways to conserve road shoulders
The road shoulder refers to a belt-like section that has a certain width from the outer edge of the roadway to the edge of the roadbed. This includes hard shoulders and protective shoulders. The road shoulder is an important component structure that guarantees the overall stability of road subgrade and road surface, and is the lateral support of the road surface. We need to properly maintain, repair, and reinforce road shoulders. This is directly related to the stability of the road surface and the smooth flow of traffic.
The main functions of the road shoulder are: protection of the main structure such as traffic lanes; pedestrians, bicycles; for the occurrence of mechanical failure or emergency vehicles need temporary parking to provide the location; so that rain can be discharged in a position away from the road, Reduce rainwater infiltration on the carriageway, reduce road damage, and more.
There are several common methods for reinforcing and improving shoulders. For example, turf reinforcement shoulders, when using this method, the height of the grass should not be higher than 100mm, otherwise it should be timely pruning, in addition weeds need to eradicate resurfacing. When the silt deposits in the road shoulder are too much to hinder the drainage, the leveling should be immediately removed. In addition to using turf reinforcement, sand reinforcement can also be used. The main material refers to mudstone or mudstone, gravel, etc. The specific process of road surface reinforcement is to mix cohesive soil with coarse sand, small gravel, weathered stone, slag, crushed concrete, shells, etc., and pave reinforcement layer with a reinforcement thickness of not less than 50mm, and try to use the groove and paving. When the shoulders are soft after the rain, the pellets can be spread directly on the shoulder and rolled.
In addition to reinforcing shoulders and carrying out maintenance activities on weekdays, it is forbidden for any person to pile up any debris on the roadside, select a site suitable for stacking road maintenance materials, and not allow important passages such as the bridge approach, the inside of bends, and steep slopes. About 5-8m, width by 2m, spacing in the 200-500m is normal range. There is also a limit to the time for stockpiling, and the treatment should be completed within a specified time. It should not exceed 10 days at most, so as to avoid affecting the normal driving of vehicles and normal transportation.
