1, and the cost is relatively high: the production process of usp low-temperature asphalt modifier and the cost of additives are relatively high, which leads to the relatively high price of modified asphalt.
2. Environmental impact: The production and use of usp low-temperature asphalt modifier will have a certain impact on the environment, such as the emission of harmful gases and the generation of waste.
3. High technical requirements for construction: usp low-temperature asphalt modifier has relatively high technical requirements, requiring professional construction teams and equipment, which increases the construction difficulty and cost.
