The gradation of the combined RAP material is presented in Figure 1 The gradation was determined in accordance with Caltrans test method CT 202 Chemical extraction was performed to determine the percentage of asphalt cement content (% AC) in the RAP, following ASTM D2172 method B The maximum theoretical specific gravity (G mm) was.
YEAR 201 201 6 CCIL CORRELATION 6Extraction Instructions Page 1of 2 EXTRACTION AND GRADATION TEST (BC, , NB, NL and SK) One sample of hot mix asphalt identified as Material (A, C or E)-EXT- (N) and one sample of hot mix asphalt identified as Material (B, D or F)-EXT- (N) have been provided TESTING.
The normal expectation would be that the difference between two results on a split sample would be considerably less than this maximum acceptable range For gradations obtained from asphalt mix samples by ignition or extraction, AASHTO T 30 gives the following multi-laboratory precision, based on the percent passing range:.
