J-1.Recycled Concrete Aggregate, a SustainableOption from Demolition Concrete Waste- A
Percentage Replacement MethodAUTHORS:
Praveen Mathew
Jeevan Jacob
Leni StephenThomas Paul
(2014)
OBJECTIVE:
To find out the percentreplacement that offers a betterstructural property in comparison
with the conventional concrete.Selected Replacements:
0% (NAC),
20% (RAC 20),
30% (RAC 30) and
40% (RAC 40)
CONCLUSION:
1. Recycled aggregate is anidealsubstitute for the naturalaggregate in structural concrete.
2. Maximum Values ofstrength were obtained at40%replacement.

J-2.Performance of Rigid
Pavements containing RCAAUTHORS:
GREGORY D/ CUTTEL
MARK B/ SNYDER
JULIE M/VANDENBOSSCHE
MONTY J/ WADE
OBJECTIVE:
1. To identify the material andpavement design factors thathave resulted in both Goodand Unacceptableperformance.
2. Field study focused on thecauses of pavement distressesassociated with the use ofRCA in PCC surface layers.
CONCLUSION:
1. Comparable Pavementperformance between recycledand conventional PCC pavements
was especially common whenthere weresimilar amountsofnatural aggregates in the PCCmixtures.
2. Recurrent D-crackingwas notobserved on any of the surveryedprojects.
3. Recurrent ASRappeared to
present in small localized areas inone of the project as soon as 9years after construction.

J-3. RECYCLED CONCRETE AGGREGATE INCONCRETE PAVEMENTS: A FIVE YEAR STUDY
ON ITS EFFECT ON PAVEMENT PERFORMANCE
AUTHORS:
Federico Irali
Aleks Kivi
James T. SmithSusan L. Tighe
Cesare Sangiorgi
(2013)
OBJECTIVE:
The objective of this researchproject was to evaluate thelong-term performance ofconcrete pavements withdifferent percentages of RCAthrough the construction offull scale test sections that wasinstrumented with varioussensors to analyze andmonitor pavement responses
over time.
CONCLUSION:
1. Four experimental concretepavement sections, eachcontaining a different percentage
of RCA in the concrete mix, were built at the CPATT test track in2007 and all remain in very goodcondition after being subjected totraffic loading for more than fiveyears.
2. It suggest that the increased useof waste concrete in the form of
RCA is feasible in concretepavements, if performancecomparable to virgin materials can
be expected

J-4.USE OF RECYCLED
AGGREGATE CONCRETEAUTHORS:
M'/ T"!ha' R
So$a.a$e
D'/ S"$i& S/ Pi*+&ia'
OBJECTIVE:
1. To find out the % usefeasible for construction.
2. To reduce the impact ofwaste materials onenvironment.
3. To carry out different testson recycled aggregates &natural aggregates & comparetheir results.
4. To find out the ways of costsaving such as transportation,excavation etc.
CONCLUSION:
1.Use of recycled aggregate up to30% does not affect the functionalrequirements of the structure as
per the findings of the test results.2. Various tests conducted onrecycled aggregates and resultscompared with natural aggregatesare satisfactory as per IS 2386.
3. Due to use of recycled aggregatein construction, energy & cost oftransportation of natural resources
& excavation is significantly saved.
