For asphalt pavements, the current construction process is paving the pavement first and then paving the curb. Therefore, we should make all the preparations before the construction. First, survey and set out on the new road surface, cut the seam along the edge of the road surface, and excavate the excess part to form the curb working surface.

Curbs are generally required to protect the road surface and regulate the road shape on both sides of the road. In order to make the kerb stone and road surface proportion coordinated, strong and beautiful, the size of the prefabricated block becomes larger. Large prefabricated blocks has certain difficulties for handling, and bumping is serious during transportation. If it is subjected to strong extrusion after installation, the prefabricated block is easily offset, and the integrity is poor, which affects the appearance and protection of road surface.

With the development of highway and domestic machinery manufacturing technology, power curber machine has been applied to the construction of highway curbs. It has broken through the traditional manufacturing mode and has a very high site versatility. In a variety of harsh conditions, it can be produced on-site, which can avoid material waste during prefabrication and loss in transportation and installation. It has been widely used in road construction in many provinces across the country, and has achieved good economic and social benefits. The curb pouring machine is used to form the curb stone, which has the advantages of high speed, high efficiency, smooth product line shape, good integrity and high compactness.

Compare with traditional prefabrication technology of curb, concrete curbing machine is more economical and practical. The production of curb sliding mold forming machine breaks the original operation mode and is produced on the spot, which can save about 30% raw materials and save cost 25%-35%. Because the curb is directly formed on the site, and can be embedded in the ground as the foundation. Therefore, the formed curb stone is linear, has a beautiful appearance, and also has high impact strength and stability. Its overall strength and stability are unmatched by the traditional curb prefabrication process.

The operation of the mortar spraying machine should refer to the industrial standard, check the work system and safety devices before the machine starting to work.

Connect the conveying hose and sprayer, add water into hopper, and start motor and discharge most of water for wetting hopper, pump and hose. First start the air compressor and open the damper the machine starts to work after adding sprayed materials, it is forbidden to rotate in the state of no material or water in the hopper. The amount of remaining mortar should not be less than 1/3 of the depth of the hopper, prevent air from entering the pumping system and causing air resistance.

The spraying thickness is should not be more than 8mm one time, when the thickness exceeds 8mm, multiple sprays should be made. When the materials for indoor wall is different, the low hydroscopicity wall should be sprayed firstly. When spraying the mortar on the outdoor wall, it should be cycled from top to bottom according to the s-shaped route. The bottom mortar should be sprayed in sections, the width of each sprayed construction section is 1.5m~2.0m and the height is 1.2m~1.8m.

Once the spray pipe is blocked, the switch is switched to the manual position, only the air compressor is opened, remove the quick connector in front of the pump head, and turn the nozzle down and plug it, the air compressor will blow out the residual pulp of the conveying pipe. Then install the quick connector and start working normally.

Workers should wear safety helmets, protective glasses, protective clothing and other protective equipment.

The cutting time has always been a factor to be considered in road construction, cutting crack is an important step in the road maintenance. If the slitting time is not properly controlled, it will cause great damage for next crack repair. If the slitting time is too early, the strength of the concrete is not enough to meet the cutting strength requirement, and it is easy to cause the phenomenon of missing corners. If the time is too late, the stress generated by the temperature cannot be released in time, and when the stress exceeds the limit of the flexural strength of the concrete, the phenomenon of breaking the plate is caused. If any of these two conditions occur, the slit will lose its meaning, so it is very important to accurately control the cutting time.

The slitting time has a great relationship with the temperature. At the same time, different temperatures, the slit will not be the same. Under normal circumstances, the cutting time should not exceed 24 hours.

Unreasonable depth of cut seam has a great influence on the construction of the road surface, and also has a very important impact on the service life of the road, which leads to the mixture not fully utilizing its own potential and causing wasteful resources. Further, if the depth of the slit is too deep during the construction process, it causes a large amount of wear of the saw blade, and wastes a lot of manual labor, and can not achieve the desired effect. If the depth of the slit is too shallow, the panel cannot be broken at the corresponding position.

Asphalt recycling machine can recycle asphalt pavement, which can save a lot of raw materials such as asphalt and sandstone, and it is good for treating waste and protecting the environment. The recycling equipment can reclaim, heat, crush and sift the old asphalt pavement mixture, regeneration agent, new asphalt and new aggregate are remixed into new mixture at a certain ratio, and the workers relay mix materials to the road surface.

Note:

The proportion of the mix ratio should fully consider the aging degree of the old pavement materials. During the recycling process of the old materials, do not mix dirt and other debris. If it has been mixed, clean up so that it can affect the quality of the recycled mixture, reduce the durability of the road.

1. Basic level processing: the roadbed surface should be kept firm, flat, clean before spraying non-curing coating. Corner should be made of 50mm*50mm bevel or radius of 50mm rounded.
2. Heat and melt rubber asphalt waterproof: the non-cured rubber asphalt waterproof coating should be placed in a heating tank and heated to a liquid state. Only when the specified hot temperature is reached can the construction be carried out. The heating temperature of manual scraping should be greater than or equal to 120 Celsius degree, and the spraying appropriate temperature is 150 Celsius degree.
3. Spray non-cured paint: knife coating or spraying with machine the melting non-cured waterproof paint on the subgrade, the thickness is generally between 1.5-2mm. After the non-curing rubber asphalt waterproof coating is applied, the waterproofing coil is rolled within 3 minutes, so that the coil and non-cured rubber asphalt waterproof coating are firmly bonded together to form a full-stick waterproof system.
