Abstract
A method is shown for preparing cold-process bituminous coatings, in particular the preparation of wear surface dressings which method includes the steps of preparing a bituminous binder as a cationic emulsion of bitumen; preparing an aggregate comprising at least one first aggregate fraction; and forming said cold-process bituminous coating formed with at least said aggregate interpenetrated into said binder; characterized in that said step for preparing said aggregate comprises a step for coating said at least one first aggregate fraction with lime.
Claims25
A method for preparing cold-process bituminous coatings, in particular of wear surface dressings (WSD), comprising the steps of:
- (a) preparing a bituminous binder as a cationic emulsion of bitumen,
- (b) preparing an aggregate comprising at least one first aggregate fraction, and
- (c) forming said cold-process bituminous coating formed with at least said aggregate interpenetrated into said binder;
- characterized in that said step for preparing said aggregate comprises a step for coating said at least one first aggregate fraction with lime.
A cold-process bituminous coating composition comprising a bituminous binder initially as a cationic emulsion of bitumen and an aggregate, characterized in that said aggregate is an aggregate coated with lime.
