Densely Graded Basecourse (DGB) is a well graded base course material with a typical nominal top size of 20mm.
DGB materials are manufactured under controlled conditions promoting consistency and resistance to distortion. For DGB compliant with RMS specifications 3051, please contact the Graymont’s sales team. Further information and technical data is available upon request.
