       Notes - general: A petrographical examination has been made of the
                        morainic sand fine-aggregate used in Ralumac slurry
                        seal surfacing.  It was found to have a complex
                        petrographical composition which, however, can be much
                        simplified as predominantly angular particles of
                        quartz and limestone present in about equal
                        proportions.  This composition possibly explains why
                        the sand is an effective fine aggregate - the  quartz
                        confers a skid-resistance matrix microtexture, and the
                        limestone provides good adhesion to bituminous binder.
