       Notes - general: Abstract: An investigation has been performed on three
                        pre-tensioned bridge beams hich are severly cracked.
                        The cause of cracking was thought to be alkali silica
                        reaction (ASR).  However, the investigation has shown
                        that the cause of cracking is uncertain. If the
                        cracking is due to ASR then it is shown that ASR has
                        little effect on the strength of a beam.
                        Recommendations are made for loading testing two of
                        the beams.  Testing of the third beam is not
                        recommended because it is unlikely that further
                        expansion will occur.  Hence, this beam is available
                        for other uses.
