CT 234 & 235 RSP Samples Announced

Today Caltrans announced that the next set of RSP samples will be testing labs' proficiency in CT 234 (Uncompacted Void Content of Fine Aggregates) and CT 235 (Percentage of Flat and Elongated Particle in Coarse Aggregate).  These samples will be distributed in May of 2012.  A check for $250 must be mailed to Caltrans by April 15, 2012 in order to register for the sample.  If you did not receive this announcement and have a laboratory that performs CT 234 and/or CT 235 you should contact the Caltrans RSP program at

Good luck!
