Apparatus and method of forming an anti-slip groove on roadway by using the non-cutting technology

Abstract

Disclosed is an apparatus and a method capable of forming the anti-slip groove in a variety of shapes without cutting concrete or asphalt pavements unlike the conventional cutting technology, with making use of a non-cutting type of pressurizing rotator ( 130 ) under the condition of predetermined temperature and pressure being maintained in such a manner that the pressurizing rotator is mounted to a lower portion of a grooving vehicle. The forming plate ( 132 ) is integrally mounted to a radial outer surface of the main body ( 131 ) by welding. A plurality of peaks ( 135 ) are formed on a surface of the forming plate ( 132 ), the peaks ( 135 ) being corresponding with a shape of the anti-slip groove to be formed on roadway. Alternatively, a plurality of peaks can be directly formed on a radial outer surface of the main body ( 131 ).
