Improvement of Bitumen Dosing Systems for Manufacturing Asphalt-Concrete Mixes

Issues of improving systems of hot bitumen dosing are considered. The design of the modernized bitumen batcher containing the vertical cylindrical element located inside the receiving container and connected with the S-shaped strain meter is presented. The principle of bitumen dosing in the upgraded batcher is in the measurement and scaling of bitumen weight displaced by the vertical cylindrical element when filling in the receiving container. The possibility of additional calculation of the density of the dosing material, which is carried out using the vertical cylindrical element of an improved form is shown. The measured value of the concrete density inside the receiving container of the batcher is used for the adaptive control over dosing. It is noted that the use of presented schemes of bitumen weight measurement simplifies the process of modernization of existing batchers and reduces the costs of reconstruction of operating asphalt-concrete plants.
