摘要
Abstract
The correlations between temperature and density of 22 petroleum asphalt samples in the range of 0-180℃were studied.A mathematical model for volume correction factor was established by using linear equations between density,reciprocal of density,logarithm of density and temperature.The volume correction factors calculated by these mathematical models were compared with the volume correction factors obtained by looking up tables in ASTM D4311/D4311-15 and the measured volume correction factors.It is found that under the premise of knowing the relationship between temperature and density,the mathematical model established by using the linear equation between the reciprocal of density and temperature is the most accurate in calculating the volume correction factor,and the ASTM D4311/D4311-15 method has the largest error.On the basis of the relationship between the logarithm of density of petroleum asphalt and temperature,a mathematical model related only to the measured temperature and the reference temperature is established.This model is simpler,more accurate and more reasonable than the mathematical model in ASTM D4311/D4311-15.关键词
