The Key Technology Research On Radar Detection And Treatment Of Void Concrete Pavement

Common diseases include cement concrete pavement panels fractured, deformedpavement seams flaking off the air pump mud, potholes, etc., and fractured, dislocationand potholes and other diseases slabs almost empty, suggesting a concrete pavementmaintenance and improvement of essential research techniques. Research in this areajust to stay in the earlier research methods and theoretical study of the content of thedistance from the application of part of the implementation still exist. Therefore,continue in-depth study of cement concrete pavement issues, focusing on analysis of thebottom plate void detection methods, evaluation criteria and treatment techniques andother issues, the further development of cement concrete pavement, with greateconomic and social benefits.In this paper, the above research status, relying Sichuan Province cement concretepavement overhaul of key technology research projects launched studies, mainly in slabvoid detection theory, assessment principles, analysis of the effect of treatmenttechnology aspects, as follows:①Describes the electromagnetic wave propagation characteristics and geologicalradar works, made of old cement concrete pavement void radar detection system andmethod for selecting and setting parameters void detection radar detection plate at theend, come to surface radar detection slabs empty steps.②Through the study of GPR image feature extraction and object recognitiontheory, cross-sectional view of the detection data obtained were processed and imageinterpretation, feature extraction of radar cross-sectional view of normal road pavementand void.③Void deflection detection methods for geological radar and recommendedspecifications, technical and economic comparison showed radar detection cementconcrete pavement engineering applications with better results.④From the scope of application, recommended test methods to detect radarconcrete slabs empty proposed technical requirements, instrument parameters, testprocedures, the results of radar cross-section image recognition void criterion.⑤Presents two end plates suitable for road void treatment technology: impactcrusher programs and MHB program. Through the process of compar ing the effects of different construction, proposed indicators and criteria void treatment bottom platequality control, draw their scope.
