The quality of road asphalt products, in addition to controlling  oxidized asphalt the quality of the equipment and raw materials produced, can also be controlled by the production process. The quality of the process control products can be controlled from three aspects, which are summarized as follows:

(1) Temperature control. In the modified asphalt technology, in addition to materials and equipment, temperature adjustment is very important. The melting point of SBS modifier is about 180 ° C, the higher the heating temperature of the main asphalt, the easier the SBS modifier is to dissolve, and the The faster the dissolution rate. However, the asphalt temperature is too high, and it is easy to age, and the SBS modifier is oxidized, decomposed and damaged, resulting in a decrease in performance. Therefore, the temperature of the primary asphalt should be scheduled between 175 and 180°C. In addition, the usage of travel asphalt decreases for a long time during high temperature storage, so it is assumed that the temperature of around 130°C can be controlled for long-term storage, which will not affect the policy. . We have equipped the boiler with a clear and detailed temperature indicator that can directly influence temperature control in a good way.

2) Damaged. The mill is the key equipment in oxidized asphalt the whole process. Two high-speed cutting mills are produced for vehicle asphalt, and the vacancy of the grinding disc can be adjusted according to the particle size obtained by the micro-investigation experiment. Because if the vacancy is too large, the SBS mixture particles cannot be small, and the SBS and asphalt mixture cannot be uniform, which will affect the product quality; if the vacancy is too small (less than 1 mm), the resistance force will increase the temperature of the asphalt, which can cause the asphalt to age. We use the process of flow operation of two mills, grinding through two different vacancies between the two mills, on the one hand to reduce the number and possibility of oversized particles, on the other hand to reduce the conflict, and change the asphalt because of the aging temperature too high.

(3) Product control: Preparing for postpartum (warehousing) and postpartum (warehousing) testing and recording original data in detail, each batch of products must pass inspection and certification before being transported to the highway section. Assuming the product cannot be inspected, it is piped to a premix container for processing.If you have any other questions, please contact  oxidized asphalt us for details or contact us directly.
