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,
Community road construction "Selection of materials" The materials required for mixing asphalt mixture mainly include coarse aggregate, fine aggregate, mineral filler and asphalt. , Asphalt mixture proportion design The key to the quality of asphalt pavement lies in the mixture proportion 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 the 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 be strict. Controlling the gradation of incoming aggregates
Controlling the mix ratio during construction Due to the variability of aggregates, it is difficult to mix the gradation of the mixed materials during the construction process and the mix ratio design The mineral material gradation is consistent. In order to reduce the volatility of grading, in addition to strengthening the inspection of incoming materials, the laboratory should continuously track the grading of hot silos, and conduct a comprehensive inspection of the grading of hot silos before construction every day. Screen the materials and compare the results with the production mix ratio. If the difference is large, make adjustments immediately to ensure that the mineral gradation of the mixture is within the allowable fluctuation range of the mix ratio. Inspection of asphalt mixture during construction
During the construction process, the performance inspection of asphalt mixture is to supervise the production process of the mixing station, verify the fluctuation of mineral gradation, and inspect the asphalt content
br/>An important basis for quality 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 key construction techniques to ensure road compaction and smoothness》
Second, undertake the construction of colored asphalt pavement
Hot-mix colored pavement is hot-mixed with colored stones and colored asphalt and mineral pigments are added.
It is hot-paved and rolled. Colored asphalt is a synthetic dyeable asphalt. Its
mechanical properties are The 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 dye
color are selected accordingly. The color of the stone is very important for the color durability of the colored pavement
Importantly, the final color of the pavement is closely related to the color of the stone
