Sustainable Alternative Materials in Unbound Granular LayersThe use of sustainable alternative materials asconstructionaggregatehas increasinglybeen takingon greater importance in the pavement industry,as natural aggregates are growing in scarcity indevelopedurbanareasandsubstantialsuppliesexistof recycled concrete aggregate (RCA), reclaimedasphalt pavement (RAP) and other post-consumermaterials.Itiscrucialtoproperlycharacterizethesematerialssothattheirpropertiesareknownforbothcurrentandfutureengineeringapplications.
One such project at CPATT centers on thecharacterizationoffoamglasslightweightaggregate(LWA), conducted in partnership with FoamynaCanada Inc. and with support from the OntarioCentresofExcellence(OCE).Initiallaboratoryworkproceeded in 2015, including grain size analysis,crushed particle content, flat and elongated partialcontentandMicro-DevalabrasionresistancetestinginCPATT’sJohnJ.CarrickLaboratoryattheUniversityofWaterloo.InJanuary2016,freezingandthawingresistance testingwascarriedoutonsamplesof thefoamglassLWAmaterials.

Another research project ongoing at CPATT isexamining the potential use of RCA and RAP asaggregate inGranularBType IImaterials.OntarioProvincial Standard Specification (OPSS) 1010permits the use of RCA, RAP and other recycledmaterials in a range of granular fill classifications,but currently specifically prohibits their usage in
Granular B Type II. This research is being carriedout in partnership with the Ontario Ministry ofTransportation(MTO),AggregateRecyclingOntario(ARO),andanumberofprivate-sectorcontributorsincludingLafargeCanadaInc.(adivisionofLafargeHolcim),SteedandEvansLtd.,R.W.TomlinsonLtd.,andNelsonAggregateCo.
Acombinedfieldandlaboratorytestingprogramwascarriedout in2015on a rangeofGranularBTypeII test blends incorporating varying proportions ofnatural aggregate, processed RCA and processedRAP.Fieldtrialsincludingtestpadconstructionandexamination proceeded in the summer of 2015 atquarrysitesownedbyR.W.TomlinsonLtd.inOttawa,ON and NelsonAggregate Co. in Burlington, ON.This was followed by laboratory testing conductedprimarilyattheLafargeCanadaInc.InnovationandTrainingCentre(ITC)inToronto,ON,whichincludedgrain size analysis, standard and modified Proctor,permeability, California Bearing Ratio (CBR) andresilientmodulustesting.
More recently, this project was presented at theFebruary2016combinedconferenceof theOntarioGood Roads Association (OGRA) and the RuralOntario Municipal Association (ROMA), held atthe Royal York Hotel in Toronto, ON. This wasfollowedby successful acceptance andpresentationof a paper on the field testing program at the June2016annualconferenceoftheCanadianSocietyforCivilEngineering (CSCE) inLondon,ON.Anothertechnical paper on the laboratory testing programhas been accepted for publishing and presentationat the2016annualconferenceoftheTransportationAssociation of Canada, to be held in Toronto, ONfromSeptember25-28.

High Modulus Asphalt Concrete Mix DesignAn on-going project at CPATT is the developmentof high modulus asphalt concrete mix designtechnology based on Ontario’s conditions such asclimate,trafficloading,andavailabilityofmaterialsandspecifications.
Highmodulusasphaltconcrete,orEnrobéàModuleÉlevé (EME) in French, represents a category ofasphaltmixeswhichhasaveryhighstiffnessmodulus(dynamic or complex modulus) together withexcellentresistancetoruttingandtofatiguecracking.Itwasdevelopedinthe1980sinFrancetoaddresstheproblems of rutting and premature fatigue crackinginflexiblepavements.TheuseofEMEmixesinthepavementstructurewouldleadtoabetterdistributionof stresses and strains in the different layers of thepavement.
Basically, the high stiffness of EME mixes comesfromtwocomponents:
1. reinforcedgranularstructure;and2. hardasphaltcement.

Inthisstudy,theCompressivePackingModel(CPM)isusedtoaddressthefirstcomponent.CPMhasbeendeveloped and used for high performance cementbasedconcretematerials.Therefore,itisbeingusedinthefieldofasphaltconcreteforthefirsttime.Forthe second component, highly polymer modifiedbinderisutilizedinordertopreventfromprematurefatigue and low temperature cracking of asphaltconcretes.Theaggregatemorphologicparametersarealsodeterminedusingtheaggregateimageanalyser.Thepurposeof this test is toevaluatetheeffectsofaggregateshapesonperformanceofEMEmixes.
