METHOD FOR MEASUREMENT AND REGISTRATION OF ROAD SURFACE COATING OPERATION DATA AND FUNCTIONAL COMPLEX FOR ITS REALISATION Russian patent published in 2010 - IPC E01C23/07 G01B5/28 G01C7/04 

FIELD: construction.

SUBSTANCE: investigated parametres of road surface are at least physical-chemical indices of coating layer of dispersed system (DS) created on road surface. Analysis of chemical composition of DS disperse phases is carried out in mode of spot test by spectral-optical methods simultaneously by several functionally similar but structurally different subsystems of functional complex (FC). Final result of spot test is generated on the basis of averaging of identical indices independently produced by method of structurally different subsystems. Monitoring and measuring system uses at least the following components: subsystem of optical identification and registration of investigated physical-chemical indices, including thickness of coating layer, which is organised on the basis of pulse source of optical radiation, sent at the specified angle to surface of investigated coating layer, and receiver of reflected radiation; the first and second subsystems of spectral spot test, every of which is organised on the basis of internal optical gas analyser (G) and pulse optical radiators of wave length ranges that vary for each subsystem, and waves are facilities for transformation of phase condition of coating layer DS substance (in zone of this layer exposure to generated specified radiators of radiation flows) into dust-, gas-, steam-like mixture. Mixture is transported into G chambers. In FC subsystem of organisation of investigated substance chemical analysis is used in laboratory conditions. Results of this analysis are used to correct averaged results of spot test.

EFFECT: improved accuracy and validity of measurement results with increase of efficiency.
