Improved Rice Method for Determining Theoretical Maximum

Rice method. This necessitates the use of a supplementary (dry­ back) procedure that is even more prone to testing errors. There is a need to improve the Rice method to avoid these problems. Two dense-graded asphalt paving mixtures (representing low-and high-absorption aggregates) and one AC-20 asphalt cement were used.
