Feature Project - Determining the amount of RAP in HMA in OntarioThisprojectiscarriedoutthroughthepartnershipwiththeMinistry of Transportation Ontario (MTO), theOntarioHotMixProducersAssociation (OHMPA),DBA Engineering Ltd., and Natural Sciences andEngineeringResearchCouncilofCanada(NSERC).
The research involved a comprehensive laboratoryinvestigation on the long term performance of theRecycled Hot Mix (RHM) with 20% and 40%RAP content and compares the resultswith controlmixtureswithoutRAP.ConventionalSuperpave12.5mm surface coarse mixtures were designed withfourdifferentbindersperformancegrade:PG58-28,
PG58-34,PG52-34,andPG52-40.

CIR and CIREAMJanki’sgraduateresearchscopeexploresthefieldandlaboratory performance ofCold In-placeRecycling(CIR)treatmentwithemulsifiedasphaltincomparisonwiththeperformanceofColdIn-placeRecyclingwithExpandedAsphaltMixture(CIREAM).
Both CIR and CIREAM meet the criteria fora sustainable pavement because of the safe,efficient, economic, and environmentally friendlycharacteristics. They allow an in-place reprocessand reuse of existing road materials, without off-sitetransportation.CIRandCIREAMhasshowntoconservearound62%ofaggregate,andreduce52%ofcarbondioxideand54%ofnitricoxideandnitrogendioxide compared with a traditional rehabilitationtechnique (mill 100mm and place 130mm HMA).StudiesshowthatCIRandCIREAMcanreducethecostof42%ifa50-yearperiodwitha5%discount

For the labperformance, JankiwillbecarryingouttestsonmixedsamplesobtainedfromSouthernandNorthernOntario.Tests suchasDynamicModulus,Fatigue Beam and Thermal Stress RestrainedSpecimen Tests (TSRST) will be carried out forperformanceevaluations.
Samples of Dynamic Modulus Testing
For thefield testing, different sections of roadwayswhich have used these technologies will behighlighted. Firstly, a pavement distress evaluationfor the designated sections would be conducted.In addition, samples would be extracted from thedesignated sections to be evaluated for TensileStrengthRatio(TSR)andretainedstability.
Once field and lab data has been collected, anevaluation and statistical analysis will be carriedout with the data. It will include development ofguidelinesforusageandevaluatebestpractices.Thiswouldbeofgreatvalue for furtherdevelopmentofthesetechnologiesintheindustry.
