is the required bond strength, expressed in Newton per square millimetres (N/mm²) sn
is the standard deviation; a value of 0,4 shall be used if sn < 0,4 4 Functional requirements for concrete pavements 4.1 General The appropriate functional requirements shall be specified. Jointed unreinforced concrete pavements shall not have visible cracks. 4.2 Strength of concrete pavements 4.2.1 General The strength of a concrete pavement shall be determined from cores, which have been cut from the full depth of the slab. The concrete strength shall be determined in accordance with one of the methods given in 4.2.2 and 4.2.3. The strength class shall be selected from a characteristic value given in 4.2.2 or 4.2.3. The characteristic strength shall be evaluated in accordance with EN 206-1. NOTE 1 Classes refer to the 28 day equivalent maturity strength. NOTE 2 The criteria given in Annex A may be used for the evaluation of core strengths throughout the whole of the constructed pavement. NOTE 3 Intermediate strength classes may be selected between those given in 4.2.2 and 4.2.3. NOTE 4 The different classes given in 4.2.2 and 4.2.3 are not directly correlated. SIST EN 13877-2:2005
