Influencing factors of dynamic viscosity for multigrade asphalt cement
Based on the test principle,sample preparation,test process and other aspects,the possible influencing factors of dynamic viscosity test for multigrade asphalt cement were researched,the results showed that temperature,sample amount and homogeneity may affect the result.The relevant regulations should be strictly observed during the actual operation.At the same time,for high viscosity asphalt,include multigrade asphalt cement,the test details such as endpoint judgment in the specification need to be further improved.
