The process control method is adopted for the control of the construction quality of steel deck pavement, and the quality control method is adopted for the pavement materials, mixtures and each pavement layer to test and verify the pavement construction control effect.
For special road (bridge) pavement, cement concrete pavement special pavement and asphalt pavement maintenance technology, adhering to the business philosophy of “leading technology, professional service and sustainable development”, we are committed to providing various customers with high value-added technologies and integrated products, and providing integrated services from the aspects of scheme design, design optimization, technical services, standardized construction and later maintenance, aiming to provide customers with more professional A more hassle free user experience.
The process control method is to control the quality, that is, during the construction process of each layer from steel plate sand blasting and rust removal to the completion of pavement construction, strictly control the factors affecting the construction quality, such as control of construction conditions, construction equipment and construction technology, so as to achieve the purpose of high-quality bridge deck pavement.
The construction of the next process can only be carried out after the previous process passes the inspection.
