1: Undertake asphalt pavement construction
The main business scope includes: professional asphalt pavement construction, first and second-level highways,
Asphalt road construction of provincial, national and county roads, and asphalt pavement construction of municipal roads,
/>Residential road construction "Selection of materials: The materials required for mixing asphalt mixtures
Mainly include coarse aggregates, fine aggregates, mineral fillers and asphalt. , Asphalt mixture ratio design & The key to the quality of asphalt pavement lies in the mixture ratio design. A good mix design is the key to the success or failure of asphalt pavement construction.
Generally divided into three stages: target mix design, production mix ratio, and production mix verification
, Control of aggregates during the construction process & in order to avoid segregation of the mixture and ensure that the gradation of mineral materials during the production process can match the gradation curve of the production mix ratio to the greatest extent, the laboratory must Strictly control the gradation of the incoming aggregate
and the control of the mix ratio during the construction process. Due to the variability of the aggregates, it is difficult to match the gradation of the mixed materials with the mix ratio during the construction process
The mineral material gradation at the time of design is consistent. In order to reduce the volatility of grading, in addition to strengthening the inspection of incoming materials, the laboratory should constantly track the grading of the hot silo, and check the grading of the hot silo before construction every day. The aggregates are screened and the results are compared with the production mix ratio. If the difference is large, adjustments are made immediately to ensure that the mineral gradation of the mixture is within the allowable fluctuation of the mix ratio. Within the scope and during the construction process, the inspection of asphalt mixtures & During the construction process, the performance inspection of asphalt mixtures is to supervise the production process of the mixing station, verify the fluctuation of mineral material gradation, Testing the asphalt content is an important basis and an important means to ensure the quality control of asphalt pavement. The laboratory takes asphalt mixture at least once a day for Marshall test and extraction test. , On-site paving and rolling&In asphalt pavement construction, on-site paving and rolling are the key construction techniques to ensure the compactness and smoothness of the road surface》
2: Graded stone layer Construction
The layer is located under the surface layer (i.e., the asphalt layer). The construction can be done manually, with graders and pavers. Before the graded stone layer is initially set, a road roller is used to achieve the designed compaction degree. After construction, the water stabilizer should be sprinkled and maintained. The water stabilizer layer is the abbreviation of cement stabilized gravel layer, which uses cement to consolidate graded gravel and completes it through compaction. %~% is the cement content
Three: Undertake the construction of colored asphalt pavement
Hot-mix colored pavement uses colored stones and colored asphalt and adds mineral pigments and is hot-mixed and rolled. Asphalt is a synthetic dyeable asphalt. Its mechanical properties and rheological properties are the same as those of general heavy traffic asphalt for roads. The color of the pavement
is determined by the owner based on the landscape design, and the dye and stone materials that are consistent with or as close as possible to the color of the dye
are selected accordingly. The & color of the stone has a color durability for the colored pavement
Very important, the final color of the pavement is closely related to the color of the stone
