How Many Days is the Maintenance Period for Asphalt Pavement?
1 Answers
Asphalt concrete pavement surface does not require curing. Generally, traffic can be opened once the surface temperature drops below 60 degrees after compaction. Below is relevant information on asphalt pavement maintenance: 1. Maintenance precautions: While ensuring the original pavement structure standards, maintain the original structural strength. Asphalt pavement needs frequent removal of debris such as soil, stones, and gravel, especially at junctions with other types of pavement, where cleaning should be intensified. Mixing mortar or concrete on the pavement is prohibited to avoid contamination, which can lead to uneven surfaces or reduced skid resistance, adversely affecting traffic. 2. The optimal timing and cycle for preventive maintenance of municipal roads: The first stage is the initial usage phase after construction, during which the asphalt continuously oxidizes or wears over time; the second stage occurs after the asphalt road has been in use for some time, showing minor cracks or slight potholes; the third stage, building on the second, sees further development of defects leading to aggravated pavement damage, with large-scale cracks, even cracking and subsidence, rendering the road impassable for normal vehicle traffic.
