The construction method of fiber-added asphalt concrete is basically the same as that of traditional asphalt concrete. It is divided into incoming material inspection, mixing equipment selection, mixing, transportation, paving and rolling. However, there are also differences. Now, the fiber-added asphalt concrete construction method is The differences between fiber asphalt concrete and traditional asphalt concrete construction technology are introduced:
1. Due to the addition of fiber, the dry mixing and wet mixing time must be extended to make the fiber evenly coat the mineral material. The production capacity of the mixing equipment will be reduced by 20% to 30%. Especially in some provinces in northern my country, the winter temperature is very low. The opening time is often set in winter. This objectively determines the completion time of the asphalt surface layer, that is, the asphalt surface layer construction must be completed before the temperature turns cold. The reduction in mixing equipment capacity resulted in a longer construction period. Cold weather is very detrimental to ensuring compaction and smoothness, so when making construction plans, the mixing capacity of the mixing equipment must be considered or the construction of the subbase and base layer must be accelerated to allow sufficient and reasonable construction time for the construction of the asphalt surface layer. These factors must be taken into account when planning construction.
2. For traditional continuous mixing equipment, special fiber adding equipment must be added. Since fiber accounts for a small proportion of the mixture, the accuracy of the equipment will be an important aspect that affects the mixing quality. Uneven fiber addition will also cause As a result, the amount of oil used in the mixture is too large or too small, which affects the quality of the project. Therefore, it is advisable to use traditional intermittent mixing equipment and manually add fibers. This is more economical and easy to operate. Strict requirements should be imposed on the workers who add materials to avoid excessive mixing. Cast, miss cast.
