1 Scope This European Standard specifies test methods for determining the rates of spread and accuracy of spread of binder and chippings of a surface dressing on a section of road at a given time. It is also applicable to surface dressings on airfields and other trafficked areas. The test methods are used on site to check the ability of binder sprayers and chipping spreaders to meet the intended rates of spread and tolerances and coefficients of variation. The test methods for measuring the rates of spread and accuracy of spread of binders and chippings are not applicable to combined chipping-binder spreaders.
