18、2018EN 122746:2018 (E)1 ScopeThis European Standard specifies test methods for determination the average rate of application of slurry surfacing in kilograms per square metre (kg/m2).This European Standard applies to slurry surfacing for roads, airfields and other trafficked areas.2 Terms and defini
19、tionsFor the purposes of this document, the following terms and definitions apply.2.1rate of applicationXtotal mass of slurry surfacing applied divided by the surface of the covered area, determined in kilograms per square metre (kg/m2)2.2rate of application without processing waterYmass of slurry s
20、urfacing applied (without processing water) divided by the surface of the covered area, determined in kilograms per square metre (kg/m2)3 PrincipleThe total mass of slurry surfacing mixture applied to a known area is measured. The mass is determined either by recording each of the mixture constituen
21、ts separately (see 4.1) or by weighing the slurry surfacing machine and determining its mass both before and after laying the slurry surfacing mixture (see 4.2)4 Procedure4.1 Methods based on the separate recording of the constituentsFor a given surface area covered, record the masses of the constit
22、uents: with the delivery tickets. Make an allowance for quantities of residual stocks where appropriate. with continuous recordings, if the slurry surfacing machine is fitted with continuously operating devices to weigh the mass or to measure the volume of the constituents (transform the volume reco
23、rdings into masses using the density of each constituent).Calculate the sum of the masses of the used constituents, M, in kilograms (kg).Measure the surface area covered, A, in square metres (m2).Calculate the rate of application X or Y, in kilograms (kg), using one of the following formulae:whereX
24、is the rate of application of slurry surfacing, expressed in kilograms (kg/m2);M is the sum of the total masses of all the used constituents, expressed in kilograms (kg);A is the covered area expressed in square metres (m2).4 BS EN 122746:2018EN 122746:2018 (E)whereY is the rate of application of sl
25、urry surfacing without processing water, expressed in kilograms (kg/m2);M is the sum of the masses of all the used constituents without processing water, expressed in kilograms (kg);A is the covered area expressed in square metres (m2).4.2 Methods based on weighing the slurry surfacing machineThe to
26、tal rate of application for slurry surfacing can be checked on site by weighing the slurry machine using a fixed or mobile system.Determine the quantity of slurry surfacing materials laid by a machine, M in kilograms (kg), by using the following formula:whereM1 is the mass in kilograms (kg) of the m
27、achine after layingM2 is the mass in kilograms (kg) of the machine before layingMeasure the surface area covered, A in square metres (m2).Calculate the total rate of application X, in kilograms (kg), using the following formula:whereX is the rate of application of slurry surfacing, expressed in kilo
28、grams (kg/m2);M is the sum of the masses of all the used constituents, expressed in kilograms (kg);A is the covered area expressed in square meters (m2).For weighing the slurry machine using a portable system, weighing shall be performed on ground with a resultant slope (crossfall and gradient) smal
29、ler than 3 % (under conditions according to the operating manual of the balance).The portable weighing system shall comprise at least two connected plates, so as to be able to weigh each axle at one time. The size of the plates shall be such that the double wheels can pass over them. The minimum cap
30、acity of the weighing system shall be 15 000 kg. The limit deviation shall be 25 kg for axles up to 2 500 kg, and 50 kg for axles up to 15 000 kg. The system shall provide a recording of the mass per axle as well the date and hour. A printer may be used to provide hard copies.5 Test reportThe report
31、 shall contain:a) reference to this European Standard;b) any deviation from the procedure described in the standard;c) date of application;d) location;5BS EN 122746:2018EN 122746:2018 (E)e) procedure used (4.1 or 4.2);f) masses of all used constituents, expressed in kilograms (kg);g) Sum of the mass
