EN 12274-4:2003 (E)3ForewordThis document (EN 12274-4:2003) has been prepared by Technical Committee CEN/TC 227 "Road materials", thesecretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by August 2003, and conflicting national standards shall be withdrawn at the latest byDecember 2005.This European Standard is one of a series of standards as listed below:EN 12274-1, Slurry surfacing - Test methods - Part 1: Sampling for binder extraction.EN 12274-2, Slurry surfacing - Test methods - Part 2: Determination of residual binder content.EN 12274-3, Slurry surfacing - Test methods - Part 3: Consistency.EN 12274-4, Slurry surfacing - Test methods - Part 4: Determination of cohesion of the mix.EN 12274-5, Slurry surfacing - Test methods - Part 5: Determination of wearing.EN 12274-6, Slurry surfacing - Test methods - Part 6: Rate of application.EN 12274-71, Slurry surfacing - Test methods - Part 7: Shaking abrasion test in suitability of mineral aggregates toslurry mixes.EN 12274-81, Slurry surfacing - Test methods - Part 8: Visual assessment.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.1 ScopeThis European Standard describes a test method for determining the minimum cohesion of a slurry surfacing mixwhich enables the set time and trafficability time to be determined.This European Standard applies to slurry surfacing to be used in surface layers.NOTEFor some course mixtures the precision is poor due to loss of aggregates comes up, a comment will be made in thereport.
