Reasons for degranulation of newly paved asphalt pavement
1. Improper construction technology
Improper construction techniques are one of the main causes of degranulation of newly laid asphalt pavement. When paving, if the construction is not carried out in accordance with the standard requirements, for example, the base layer is not prepared in advance, the mix ratio is not strictly followed, etc., it will cause the asphalt pavement to be degranulated.
2. The density cannot be reached, the bearing pressure cannot be reached, and the compaction is insufficient.
3. Environmental and temperature factors
Environmental and temperature factors can also affect new asphalt pavement. For example, construction in a humid, cold environment, or construction in hot weather may affect the adhesion and lead to degranulation of the asphalt pavement.
Solution
1. Do a good job in construction technology
Before paving, the base layer must be treated, such as removing debris and broken concrete, to ensure the smoothness and quality of the base layer. Reasonably control the mix ratio of asphalt materials and maintain the viscosity of asphalt. Reinforcement and uniform compaction ensure that the asphalt pavement can be firmly bonded to the base layer.
2. Choose materials with reliable quality
It is recommended that you choose asphalt materials with guaranteed quality, and check the quality standards of the supplier's materials when purchasing to ensure that the quality of the asphalt materials is reliable.
3. Use seal coating materials for covering.
New asphalt pavement should be maintained and inspected regularly
1. Timely maintenance is key to protecting your newly paved asphalt pavement. When the road surface is contaminated, damaged or has any problems, it must be repaired and maintained in time to prevent the problem from expanding.
2. Regular inspections can detect problems on the road surface in time and take measures to repair them. It is recommended that routine inspections be performed at least once a year to ensure the quality of your new asphalt pavement.
