A method for compacting a surface of granular materials is disclosed. The method is applicable to wheeled compaction equipment such as pneumatic-tire compactors, drum-type compactors and asphalt compactors. The propel system includes a controller programmed to send a first at least substantially constant propel command that propels the compaction equipment in a forward direction. The controller then changes the speed of the compaction equipment by providing a second varying propel command that may increase or decrease the speed resulting from the first command. As a result, the speed of the compaction equipment oscillates.
