AdvertorialSynergy introduces new MOBA Infra-red technologyReal time asphalt segregation monitoringAsphalt segregation is one of the leadingcontributors to the premature failure of hotmix asphalt pavements.While asphalt manufacture is a highlycontrolled process the logistics of delivery tothe job site and final lay down by the asphaltpaver can introduce significant variablesresulting in excessive segregation. Thesevariables include loose material which hascollected at the sides of the truck duringtransportation, cold asphalt in the paver’sreceiving hopper, larger aggregates collectingduring the beginning and end of the batchingprocess at the plant, and excessive hand workafter lay down.Identifying segregation on a real timebasis while the asphalt is being laid providesthe best opportunity to highlight problemareas and avoid further failures and costlyremedial work.According to many international researchpapers, material segregation can be identifiedby use of thermal imaging. A new systemnow available in Australia from the Germanmanufacturer MOBA provides asphaltcontractors with a method of detectingsegregation in real time.The MOBA PAVE-IRTM system producesa complete thermal profile for the entireproject utilising an array of infra-redsensors fitted to an integrated system onthe asphalt paver’s screed. In addition todisplaying real-time data to the operatorvia a colour touch screen interface, projectfiles are stored and can be down loaded andtransferred to the office for review usingMOBA Pave Project ManagerTM softwarefor quality analysis and problemarea identification.52 ROADS JUNE/JULY 2012MOBA is a leading manufacturer ofasphalt paving technologies which aredistributed through Synergy PositioningSystems in Australia.“Synergy is a specialist asphalt pavingconsultancy with over 30 years experience,”said Synergy’s director, Mike Milne.“Assisting in the control of asphalt paversto achieve high survey tolerances with ourpatented paving grade control systems,we specialise in airport runways, majorroading projects and sport field constructionthroughout Australia and the Pacific.“The quality and reliability of MOBA productsover the past 20 years has been phenomenaland the new PAVE-IRTM system is yet anotherexample of MOBA’s leadership,” Mr Milne said.The new PAVE-IRTM system is now availableto paving contractors and regulating bodies forsale on a consultancy basis.For more information contact, Mike Milne on1800-980-353; Synergy’s Brisbane office on (07)3801-2242; Auckland office on (09) 444-6039;or go to www.synergypositioning.com.au.
