This European Standard shall be g

EN 13863-3:2004 (E) 4 1 Scope This document describes a method for determination of the thickness of a concrete pavement by measurements of cores taken from the full depth of the pavement. 2 Normativ
19、e references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12504-1, Testing concrete in stru
20、ctures Part 1: Cored specimens Testing, examining and testing in compression. 3 Apparatus 3.1 General Coring equipment capable of extracting cores from hardened concrete to the dimensions given in Clause 4 and in accordance with EN 12504-1. The measurement obtained by any one of the permitted proced
21、ures shall have an accuracy of 0,5 mm. The measuring apparatus used shall comply in accordance with specifications in the place of use. 3.2 Measuring equipment One of the following pieces of equipment shall be used to measure the dimensions of test cores: metal rule or tape, calliper gauge, approved
22、 suitable jig or other device in accordance with specifications in the place of use. 4 Test specimens Cores used as test specimens for thickness measurements shall be representative of the area of concrete in the pavement from which they are taken. Cores shall be taken with the axis normal to the su
23、rface of the pavement and the ends shall be characteristic of the upper and lower surfaces of the pavement. Cores that show abnormal defects or that have been damaged appreciably in the coring operation (for example, cores that are fragmented, split or curved) shall not be used. NOTE 1 The recommend
24、ed diameter of the cores is 100 mm or 150 mm. NOTE 2 To prevent undue damage to the pavement surface, cores should not be extracted at points where high stresses can occur such as corners of slabs and not within 0,5 m of any joint. The ideal locations for taking cores are between the quarter points
25、along a slab in a jointed pavement, and between two consecutive transverse cracks in a Continuously Reinforced Concrete Pavement and a Continuously Reinforced Concrete Roadbase. NOTE 3 When taking cores to check for compliance with the design the positions for cutting the cores should be agreed in a
26、dvance by the relevant parties. EN 13863-3:2004 (E) 5 5 Procedure Measurements on cores shall be made between the upper and lower surfaces, or between well defined construction demarcation lines in cases where layers of other materials are bonded to the concrete, using the apparatus specified in Cla
27、use 3. Measurements should be made, either with the core standing firmly on its top end and in a vertical position, approximately perpendicular to the upper plane of the core, or with the core laid on a level surface in a horizontal position and rolled as necessary to permit the taking of all measur
28、ements. The length of the core shall be measured at four points evenly spaced around the circumference of the core. The positions of these measurements shall be clearly marked on the core. The measurements shall be determined to the nearest 1 mm. The average of these four measurements shall be the l
29、ength of the core. NOTE Exceptionally, where cores are damaged, measurements to determine the pavement thickness can usually be made from measurements on the side of a cored hole. This situation can arise, for example, when concrete with a low strength is used, especially in a multi-layer constructi
30、on with a weak bond between layers; in these circumstances cores may fragment during coring. 6 Results The thickness of the concrete pavement shall be taken as the average length of the core determined by the procedure in Clause 5. The measurement shall be reported to the nearest 1 mm. 7 Test report
31、 The test report shall contain the following information: a) reference to this document; b) unambiguous identification of the cores; c) dates of receipt and testing of specimens; d) details of the measurement apparatus used; e) the individual measurements and the average value for the core; f) any d
