First, the general situation of the project.
This project is a city road reconstruction project, aiming to pave the original concrete pavement with asphalt to improve the wear resistance, anti-skid and noise reduction performance of the road. The project is 2 kilometers long, involves a road width of 24 meters, and the construction period is 60 days.
2. Preparation for construction.
1.Personnel organization: set up a professional asphalt paving team to ensure that the personnel have the corresponding professional skills and construction experience.
2.Material preparation: purchase high-quality asphalt materials to ensure that the quality meets the relevant national standards; Prepare sufficient auxiliary materials such as stones, sand and gravel.
3.Equipment commissioning: Conduct comprehensive inspection and commissioning of asphalt mixing station, paver, roller and other equipment to ensure the normal operation of the equipment.
4.On-site investigation: Conduct a detailed survey of the construction section, understand the condition of the road surface, and formulate a reasonable construction plan.
Third, the construction process.
1.Pavement cleaning: Thoroughly clean the original concrete pavement to remove debris and oil stains to ensure that the pavement is dry and tidy.
2.Damage treatment: repair the damage and cracks existing in the concrete pavement to ensure the flatness of the pavement.
3.Asphalt mixing: The asphalt material is mixed according to the design ratio to ensure the uniformity and stability of the mixture.
4.Paving construction: The asphalt mixture is paved with a paver to control the paving thickness, flatness and other indicators.
5.Rolling forming: The asphalt pavement after paving is rolled by a road roller to ensure that the road surface is dense and smooth.
6.Joint treatment: special treatment is carried out on the transverse joints of the asphalt pavement, and the cold joint technology is used for lap joints to ensure that the joints are tight and smooth.
7.Quality inspection: The quality inspection of the paved asphalt pavement is carried out, including flatness, compaction, thickness and other indicators to ensure that the construction quality meets the design requirements.
8.Maintenance and open traffic: according to the local climatic conditions and asphalt performance indicators, the asphalt pavement is reasonably maintained to ensure the quality of the pavement; After reaching the conditions for opening traffic, open traffic in a timely manner.
Fourth, quality control.
1.Material control: select high-quality asphalt materials to ensure that the quality of materials meets relevant national standards; Carry out quality inspection on auxiliary materials such as stone, sand and gravel to ensure the quality of materials.
2.Equipment maintenance: Regularly inspect and maintain construction equipment to ensure that the equipment is in good condition.
3.Construction monitoring: advanced construction monitoring technology is used to monitor and record the asphalt pavement construction process in real time, and find and solve the problems in the construction in a timely manner.
4.Quality inspection and acceptance: strictly implement the quality inspection standards, and conduct multi-faceted testing on the asphalt pavement to ensure that the construction quality meets the design requirements; After the completion of each construction stage, the acceptance work is carried out to ensure that the progress of the project is synchronized with the quality.
5. Security measures.
1.Safety warning signs and safety protection facilities are set up at the construction site to ensure construction safety.
2.Carry out safety education and training for construction personnel, improve safety awareness, and ensure that no safety accidents occur during the construction process.
3.Strengthen safety management during the construction process, regularly inspect the safety status of the construction site, and discover and solve potential safety hazards in a timely manner.
4.Carry out regular maintenance of construction equipment to ensure the safe operation of equipment; At the same time, the operator is equipped with safety protection equipment.
