3.Pavement base construction
After the subgrade is improved, compacted and maintained by adding modified materials, the construction of the subgrade of the pavement begins. The pavement base is an important load-bearing structural layer of the road. It includes two parts: the sub-base and the base. The paving of the test section is carried out according to the standard regulations, so as to form the corresponding technical documents and provide the basis for the subsequent construction operations.
The sub-base materials are all inorganic bonded stabilized materials, which include the following types: cement stabilized soil, lime stabilized soil, lime industry stabilized waste residue, etc. Various stabilized materials can be mixed on-site along the road, or can be mixed centrally by using stabilized soil mixing stations. . The sub-base road mixing construction is completed by using a stabilized soil mixer to mix the materials that meet the technical requirements, and then followed by a single-drum road roller for compaction and a grader for leveling. The factory mix construction is to obtain qualified materials through the stabilized soil mixing station, and then use the stabilized soil paver to realize the forming and paving, and the compaction is completed by the road roller.
The base layer must be constructed on the premise that the lower bearing layer satisfies the surface smooth and solid, has the specified road arch, and its flatness and compaction meet the requirements of the specification, mainly including cement-stabilized base and lime-stabilized base.
The grass-roots construction adopts the factory mixing method. First, the lower bearing layer is cleaned and sprinkled, and then the staking is carried out, and then the stabilized soil mixing station produces stable materials that meet the design requirements, which are sent to the construction front site by transport trucks. Paving and rolling of stable materials are carried out, and finally appropriate watering is carried out to lay felt cloth to cover and maintain.
