Why didn't Hongyun Street in Hanshou County build asphalt road?

The asphalt road was not conducive to the development of the city and was stopped by the local government. Reason:

1, the asphalt mixture is estimated to have less asphalt, low asphalt-aggregate ratio and poor adhesion between asphalt and aggregate.

2, low temperature construction, low degree of compaction, asphalt surface internal porosity is too large.

3. The silt content of aggregate exceeds the standard, and the aggregate particles are wrapped by dust, so the asphalt film cannot be bonded to the aggregate particles.
