The influence of weather factors on asphalt paving      

In most construction sites, weather factors are within the scope of consideration only when the construction period is tight. However, in hot asphalt paving, weather factors will have a greater impact. At low temperatures, or the distance between paver and mixing station is too far, will lead to lower temperature of paving material, so that it is not suitable for paving.

1, depending on the use of different types of asphalt, when the paving material dumped into the hopper before the temperature is less than 120 degrees, paving layer in the compactor after compaction, it is difficult to achieve the desired density.

2, since the ambient temperature will lead to rapid decline of paving temperature, we suggest that you should not wear paving when the temperature is lower than 3 degrees or below 6 degrees centigrade.

3, the bond layer contains more aggregates, these aggregates are conducive to paving insulation, so it can be paved at zero degrees Celsius temperature.

4. The paving of the base can even be carried out at -3 C, but it should be ensured that there is no frost or snow at the bottom.

5, whether suitable paving can not only consider the environmental temperature: also should take the foundation temperature into account, if the foundation temperature is too low, also will cause the paving material to quickly cool down, it is difficult to achieve the expected density.

6. It is not recommended to spread on wet or even muddy subgrade. Hot asphalt contact with wet foundation will produce water vapor and form pores. Therefore, reducing the bearing capacity and compaction effect of paving materials will also have adverse effects on the suspension of the screed.

7, when paving asphalt, because of its boiling point is too high, but not likely to form water vapor.
