1, in the use of the paving machine, how to do a good job in the maintenance of hydraulic system? Answer: in the use of the paving machine, do a good job in the maintenance of hydraulic system, you can greatly reduce the fault. General should pay attention to the following points: (1) hydraulic oil in hydraulic tank joined the former, should use clean containers of oil, hydraulic oil must be after oil filter filter, then add the hydraulic oil tank; the replacement cycle of the hydraulic oil as the oil quality and (1000h changed once; replacement of hydraulic oil should be in the working temperature; in order to ensure good heat dissipation of the hydraulic system, should also regularly clean hydraulic oil radiator. (2) due to the asphalt paving machine construction environment is generally relatively poor, hydraulic oil filter replacement cycle should also be shortened (generally was750h is appropriate), replacing with a new filter element, when should be checked, prohibited the use of deformed, pollution or rusty filter. (3) in the daily start of the engine work, should be idle for some time after the operation, and then to control the implementation of components, so that the use of hydraulic pump. (4) due to the long-term use, the hydraulic system parameters will change, therefore, should be regularly check the hydraulic system parameter settings, to be adjusted in time.

we know commonly Bitumen Penetration as penetration grade bitumen. Firstly, It is a standard form of bitumen that we graded based on its hardness level. Secondly, we determine this grading through a penetration test. And Which we measures the depth a standard needle penetrates the bitumen under specific conditions. In conclusion The penetration value of bitumen is crucial as it indicates its suitability for various road construction applications, for instance.
The production of penetration grade bitumen involves a series of steps: Distillation: However, Crude oil is initially distilled in a refinery to separate the lighter fractions from the heavier ones. And It resulting in raw bitumen. Refining: In addition The raw bitumen undergoes further refining to remove impurities and to achieve the desired consistency.
Oxidized bitumen, often referred to as blown bitumen is a specialized form of bitumen. It is created through a process that significantly alters the properties of the standard bitumen, making it more suitable for various industrial applications. This type of bitumen is distinguished by its increased resistance to water and temperature changes, playing a pivotal role in road construction and waterproofing solutions. It is produced by bitumenoxidized company
Oxidized bitumen is produced by bitumenoxidized company , plays a significant role in road construction, including: Waterproofing Layers: Acts as an excellent waterproofing agent, preventing water ingress into the road base.
