Several studies have shown that the long-term performance of asphalt pavement near a longitudinal joint can be predicted by the material density near the joint just after construction. However, the asphalt material near a joint is less homogeneous than the material in the middle section of a lane...
PURPOSE: To dissolve asphalt in an organic solvent, measure density of the solvent with an oscillation densitometer and exactly measure the density of asphalt in a short time in addition to simple operation. ;CONSTITUTION: A desiccating agent is filled and a glass tube (specimen cell) 4 whose...
