LABORATORY STUDY ON DRAINDOWN OF ASPHALT CEMENT IN STONE MATRIX ASPHALT

Draindown of asphalt cement is one problem encountered so far with stone matrix asphalt. A simple test to quantitatively measure draindown was developed in this study. A round robin study was conducted to measure the variability of the test method and a detailed experiment was carried out to find the effects of the percentage passing the 4.75 mm (No. 4) sieve, stabilizer, filler, and asphalt content on draindown. Results of the round robin study showed that the proposed test method is a good test to distinguish between mixes with and without draindown potential. Draindown of asphalt cement was found to be affected significantly by type of filler, the percentage passing the 4.75 mm (No. 4) sieve, the asphalt content, and the type and amount of stabilizer.
