Small roller is used for paving construction materials such as paving material asphalt mixture gradation macadam and roller concrete material etc. It is key equipment for constructing all grade highway and municipal road ditch lower channel airport square dam parking area and exterior layer.

Operator manipulation technique has great influence on engineering quality in highway construction except for using various switches buttons highway pavement width wider maintaining direction error is particularly very tense. Commonly used methods are lime sprinkle guide lines small roller guide chain along a reference line can also be used locally. The external contour of curb stone is selected as baseline which can guarantee the distance plate between plate side baffle and edge of road stone.

Practice confirms that small roller rollers show obvious results reducing scraping and touch containment. Not only does careful guide rod chain alignment line but also careful parking must be placed parallel to track and route. Besides initial adjustment stage steering wheel isn't too big 10 degrees should be appropriate return again play to ensure steady direction development.

If mini roller adopts hanging line method on bottom layer and middle layer while middle surface layer and upper layer can be paved with non contact electronic balance beam datum or contact leap balanced float balance roller paving result will be better.
