Want to know, how should the dilapidated road pavement in rural areas be transformed?

As an important part of rural road reconstruction and upgrading, rural highway pavement reconstruction has an important impact on improving the traffic capacity of rural roads and the overall level of road network. Designers must conduct in-depth research, carefully analyze, take practical measures, and put forward a "practical, safe and economical" pavement reconstruction design plan to ensure that rural roads become safe, environmentally friendly, comfortable and economical green projects.

The survey content of rural roads mainly includes pavement type, plate thickness, slab bottom clearance, etc. According to the survey, most of the rural roads are cement concrete pavement, and the diseases can be divided into four categories: fracture, deformation, joints and surface. The main diseases are transverse and transverse pavement cracks, slab corner cracks, floor folds, exposed rebar, pavement pitting and joint spalling.

The following principles of reform can be followed:

1) Adjust measures in a timely manner. The renovation plan should anticipate the long-term traffic load demand to adapt to the current trend of rural population growth and rapid traffic growth. Using the "four-stage calculation method" ** future traffic volume, comprehensively considering the road use function, technical level, traffic volume, topography, geology, construction methods and other factors, it is necessary to have sufficient strength and stability, but also to take into account the economy, and reasonably improve the level of road traffic.

2) Adapt measures to local conditions. On the basis of the survey and the amount of local traffic, the thickness and material of the pavement structure layer are determined according to local needs. If a road section is converted into a transport corridor, different pavement materials should be selected according to the mode of transport.

If the existing road is used for retrofitting, the surrounding environment should be changed as much as possible. In the process of investigating and determining the pavement structure layer, the difficulty and operability of the construction should also be considered in combination with the actual situation.

3) Grasp the situation. The improvement of rural roads should adapt to local economic and social development and relevant standards and policies, keep up with the trend of the times, and fully consider the layout of villages and towns, industrial development, topographical conditions, ecological environmental protection and financing capacity. Give full play to the travel needs of villagers to ensure the comprehensive revitalization of the countryside.

I think it is necessary to adapt to local conditions, if it is a relatively small rural road, you can re-pave the road surface, which is more durable.

I think the first thing is to remove the old pavement and then re-apply a layer of cement on top of the original foundation.

In fact, you can choose to renovate it, you can put some asphalt, so that it will look newer.

I think that the first thing to do is to remove the old pavement, then re-lay the foundation and lay the cement.

There are several reasons why rural roads are dilapidated:

(1) Birth defects.

Most of the core samples of the pavement base are loose and unformed, with poor integrity and poor adhesion between the base and the surface layer. The main reason is that the rural roadbed is only shallow treatment or has not been treated in the early stage. After some road sections are laid with a layer of gravel cushion, the cement concrete pavement is directly laid, which is easy to produce reflection cracks, pavement settlement and other diseases.

2) Improper construction.

If the lap width is not enough, the edge of the roadbed is not filled, and the roadbed is not compacted in place in the process of widening, the roadbed is easy to produce uneven settlement, resulting in the deformation of the roadbed, and even cracking and dislocation; Concrete pavement cutting is not timely, the cutting time is not accurate, and the cutting depth is not enough, which will lead to transverse cracks.

(3) The structural design is unreasonable.

In the early days, rural roads were not designed according to standards, such as the thickness of the concrete slab of the old pavement, the excessive length-to-width ratio of the slab, the excessive plane area, and the insufficient flexural strength of cement concrete. Expansion joints and reinforced concrete slabs are not provided before and after the bridge structure.

4) Lack of drainage measures.

Most rural roads have natural drainage systems and no drainage systems. During the flood season and rainy season, the water accumulation is serious, and some roads have been flooded for a long time; Summer rain and winter snow seep into the pavement structure through cracks in the pavement, aggravating damage to the pavement and base layer.

5) The maintenance is not timely.

After the construction of rural roads is completed, there is no perfect maintenance system. Residents often repeatedly plough the soil shoulder and roadbed slope, resulting in the loss of soil shoulder and slope in some road sections, siltation of side ditches, poor drainage, and water stains on the roadbed and road surface.

Pavement modification proposals.

1) In principle, ash can be used as the base layer, cement stabilized gravel as the base layer, cement concrete surface layer or asphalt surface layer as the surface layer. If the traffic flow of the reconstructed road section is large and greatly affected by the construction, the design should take into account the travel and life of residents and shorten the construction period as much as possible. At this time, concrete can be poured at the base level, and water-stabilized gravel and asphalt surface courses can be laid to speed up the transformation cycle, reduce the impact of construction machinery vibration on the surrounding houses, and facilitate residents to travel.

2) For the old road coverage section, different coverage schemes are adopted according to the coverage height of the line longitudinal profile. Before paving, the old cement pavement should be treated, and the pavement potholes, slab corners, broken plates, grouting cross joints, cross joints and a small number of cracks should be treated. For road sections with small soil thickness, cement pavement can be widened as a substrate.

Tie rods are placed between the old and new concrete slabs to ensure integrity and stability, cement is laid to stabilize the gravel base and surface. For road sections with serious pavement diseases but the overall stability of the roadbed, the old cement pavement can be used as a roadbed.

This is due to the lack of funds and the fact that these roads are in disrepair, and these roads often have some large cars or trucks passing through, so the road surface will be dilapidated. The relevant departments should allocate funds for repairs.

It is likely that the funds are not available, it is very likely that the road is in disrepair, or because the highway usually passes by some big cars or trains, etc. Professional workers can be hired to carry out repairs.

It may be that the strength of the base layer is not enough, there may be the failure of the joint material, it may be that the construction is not in accordance with the provisions of the construction, and it may also be caused by the improper maintenance management in the later stage, and the maintenance management should be strengthened, and a strict construction plan should be formulated according to the geological structure of the place.

It may be because the construction project is not up to standard, it may be because the materials used are relatively low, it may be because the road pressure in this place is relatively large, first make a good construction plan, choose the appropriate structure, and limit the traffic in this place.

Because the rural roads are in disrepair, there are often some large cars or trucks passing by the rural roads, so the damage to the road surface is relatively large, resulting in the rural highway pavement is particularly dilapidated. Renovation requires funding from the relevant departments, and professional workers are also required to carry out repairs.

The reason for the dilapidated is that it has existed for a long time, corroded by rainwater, and often passes some large cars, and does not pay attention to repairs, which is caused by people's destruction, and then it is necessary to choose cement and re-pave the road.

The requirements of rural roads are not too high, and the roadbed should be pressed and smoothed, sprinkled with water, and then paved with asphalt or cement.

The steps of repairing a rural road are, the first step, to measure the width of the highway first, to cut down the trees within the width, and then ask the excavator to dig out the roadbed, then use the road roller to flatten the road surface, and then pave the stones, hit the concrete, well, a rural road is completed in this way, the old folks no longer have to step on the dirt road to walk, and the spiritual outlook of the countryside has changed again.

Infrastructure madness transportation facilities **** recruitment salesman.

Main products: highway corrugated beam guardrail board, column, anti-blocking block, column cap, end, flange column, anti-glare plate bracket.

There is no money for the new construction of the road, and it is inconvenient for anyone to do any transportation.

<> "Rural Road "Transformation" ushered in a large number of projects.

It is worth noting that just after our country released this five-year action plan, the Ministry of Transport also put forward the strategic deployment of "high-quality construction and integrated development" around the construction of rural roads, and also announced a year-round action construction plan at the end of April, subdividing the projects that need to be built into seven major task objectives, so that all localities can build and complete.

In the construction of the next highway network, we will also promote the high-quality construction and integrated development of rural roads through the "implementation of the rural backbone road network transformation and upgrading project, the township and village basic road extension and improvement project, the rural road safety and security capacity improvement project, the rural industrial village road integration development project and the rural road service level improvement project" to promote the high-quality construction and integrated development of rural roads, so that each village can develop the "road economy", and provide a strong guarantee for the better development of rural areas and the implementation of rural revitalization strategies in various regions.

Of course, to promote the implementation of the five major projects in rural areas also need to do a lot of preparatory work, in addition to the financial guarantee, talent construction and other aspects of the hidden years, infrastructure land security is also very important, more involved in a wide range, the amount of work is huge, not a moment and a half will be able to complete, but also need to be divided into time, sub-regional, orderly implementation. Therefore, when our country implements these projects, it will also take into account the local development needs and the living and production needs of the villagers to decide whether to start or not, which must be clear.

In short, rural revitalization, industrial revitalization, road construction is a part of the development of the stove only open, how to make each village because of the road and prosperous" "because of the road and rich" "because of the road and beauty is currently a priority in many places, our country is not to say in the countryside to build a road, build a bridge can make the economic development of the village, but to adopt the strategy of integrated development, integrated construction to drive the development of rural areas in a better direction.

Having lived in the countryside for many years, I would like to share my views. Since the road is built with the funds of the group, of course, the group must invest in the maintenanceIf there is a surplus in the account for road shearing and repair, then it can be regarded as the maintenance of the road. However, for pavements repaired after June 2018, the state has also proposed a two-year warranty period, where damage must be carried out by the construction company within two years.

In the past, the countryside was full of muddy roads, and everyone had certain difficulties in traveling, and because of the muddy roads, processing factories were reluctant to invest in projects in the countryside, and businessmen were unwilling to guarantee the purchase and sale in the countryside, so the countryside was of course poorer. Therefore, the state has also put forward the slogan of "Household Communication" to carry out hard bottom popularization for rural roads, so as to make it more convenient for farmers to travel and improve the economic vitality of rural areas.

The construction of rural roads is generally raised by the masses and subsidies from the state, after all, the amount of construction required for road construction is relatively large, and the state is unlikely to subsidize all of them. Once the road surface built with crowd funds is damaged, who should carry out the repair? After the ground of the road built by the rural group is damaged, there is no doubt that the group will pay for the repair, and people will usually be sent to maintain it.

According to the new national regulations, the quality of the roads built in rural areas will be repaired and maintained by the contractor for life, so as to avoid cutting corners.

Although it is said that the rural road is built by the group and the ground is damaged, the masses can report the situation to the villagers' committee, and the village committee will inject funds to invite people to repair and carry out maintenanceIf you can squeeze in time to pass through the sewage ditch on both sides of the village road, and carry some soil to pave the slope on both sides of the road, you can avoid floods from washing out the road, right, and maintain the village road, and the villagers start from me.

After the road surface is damaged, it is generally repaired by the local **, or the villagers raise funds to repair it together.

After the road surface is damaged, it should be repaired and maintained by the farmer, and everyone can discuss it.

In such cases, it is generally through the relevant person in charge to raise a series of funds from the villagers, and then carry out repair and maintenance.

In addition, in the future, everyone will jointly fund the repair, so that some problems can be better solved and some economic problems can be prevented.

To damage rural roads, you should first pay compensation (compensation) for road property damage to the highway management agency; If you deliberately damage a rural road, you may be in violation of the criminal law and you will need to bear criminal liability. According to our law, the destruction of highways; where it is sufficient to make the car in danger of being destroyed, but no serious consequences have been caused, a sentence of not less than three years but not more than ten years imprisonment is to be given.

Article 117 of the Criminal Law of the People's Republic of China.

damage to tracks, bridges, tunnels, roads, airports, waterways, lighthouses, signs, or other sabotage; Where it is sufficient to cause a train, automobile, tram, boat, or aircraft to overturn or destroy the danger of being blind, but no serious consequences have been caused, a sentence of not less than three years but not more than ten years imprisonment is to be given.

Article 119.

Whoever destroys means of transportation, transportation facilities, electrical equipment, gas equipment, or flammable or explosive equipment, causing serious consequences, is to be sentenced to fixed-term imprisonment of not less than 10 years, life imprisonment, or death.
