In 2013, my country's asphalt production modified asphalt reached 19,935,100 tons, an increase of 9.7% year-on-year. It can be said that asphalt production is increasing every year. Asphalt is also often used, but after investigating the phenomenon of asphalt, we admit that there will be some cracks in the asphalt pavement.


The asphalt does not meet the requirements of the proper climatic environment and quality on site, and has a high resistance to deformation, which causes the asphalt layer to swell at high temperatures. The soil is meaningless, and the subsoil compacts unevenly, resulting in uneven subsoil settlement.


(Under the influence of external movements, especially under the pressure of multiple super-tonnage vehicles, the asphalt pavement is differentiated and activated. Due to factors such as favorable conditions of different ethnic groups, poor soil quality, and asphalt pavement density, the initial structural assumptions have not been fully proved and Consider. The original asphalt pavement data does not meet the standard requirements, and the pavement strength does not seem to meet the requirements of locomotives. Semi-hard materials, water mills, exposure time after the implementation of semi-hard modified asphalt foundations and other factors. Natural asphalt


The natural asphalt plant tells you why there are cracks after paving? In the initial theoretical experience, bitumen with high viscosity, low consistency and low damping is preferred for early measurement of crack appearance. The nature of bitumen and bitumen is the least cause for response to bitumen measurements.


--The strength of the original paver increases, the traffic flow is not satisfied, the bus load increases significantly, the asphalt pavement is prematurely aged, and the asphalt is damaged and active. Traffic stopped quickly.


Yes, the formation oil strengthens the bond with the substrate surface to resist the fracture, which is useless. The most important data types have a significant effect on cracks in the asphalt layer. The smaller the intrinsic expansion of the substrate, the smaller the surface crack.


Basically, it is assumed that the natural bitumen or other bitumen used has cracks, which is constituted by the above-mentioned reasons. As can be seen from the above, asphalt is important in all aspects of equipment, materials, etc. Ready. D. The product has been improved for successful implementation.If you have any other questions, please contact us for modified asphalt details or contact us directly.
