1. J Wielinski et al, (2009) WMA is much like HMA, but it is produced at lower
plant temperatures than conventional HMA. The objectives of these
demonstrations were (a) to demonstrate that WMA with reclaimed asphalt
pavement could be produced and placed at lower temperatures while
yielding mix properties and field compaction similar to those of conventional
HMA and (b) to construct field test sections so that WMA and HMA
performance could be compared side by side.
2. FCG Martinho et al. (2018) This paper focuses on the comparison of the
mechanical performance of three warm-mix asphalt (WMA) blends with
recycled concrete aggregate (RCA) or electric arc furnace slag (EAFS) as
substitutes of part of the aggregate . The evaluation was carried out in a
laboratory by means of testing specimens taken from experimental
pavement sections built in real production, laying and
compaction circumstances
3. C Hettiarachchi et al. (2018) Use of reclaimed asphalt pavement (RAP)
materials in warm mix asphalt (WMA) mixtures is getting popular around the
world due to economic and environmental benefits.

4. Jony, Al-Rubaie, & Jahad et al. (2011) , Considering the glass powder (GP)
as filler, several researchers found that the use of recycled GP does not
worsen mechanical and performance properties of asphalt mixtures. For
instance, it is indicated that replacement of limestone filler by GP resulted
in lower flow rate and higher stability
5. Ayman Ali et al, (2013) A study was conducted to evaluate the effect of
temperature reduction, foaming water content, and aggregate moisture
content on the performance of foamed WMA.Two asphalt binders (PG 70-
22 and PG 64-28), two aggregate types (limestone and crushed gravel), and
two nominal maximum aggregate sizes (12.5 mm and 19.0 mm) were used
in this study.The asphalt pavement analyzer test was utilized to evaluate the
rutting resistance, and the indirect tensile strength and the Modified
Lottman (AASHTO T 283) tests were utilized to evaluate the moisture
sensitivity of the asphalt mixtures.
6. Choudry J et al. (2021) uses glass powder and glass-hydrated lime as
alternative fillers in place of stone dust. It Resulted in reduction of cost of
the pavement to 33-35% and 21% more economical and exhibited better
laboratory performance. The use of this mix can also conserve 280 tons and
28 tons of conventional aggregate and binder.

8. Objectives of the Project Work
8
 To conduct various preliminary laboratory tests on all
materials as per standard specifications.
 To design and develop a Conventional Warm Mix Asphalt
(WMA) and the Warm Mix Asphalt with Blast Furnace Slag
replaced aggregates and waste materials replaced fillers as
per standard design method in the laboratory and to
conduct standard performance evaluation tests on the
developed mixes.
 To compare the performance of both mixes and to
recommend the suitable Warm Mix Asphalt mixture with
Blast Furnace slag and fillers for the patching of pothole.

9. Methodology
9
 The first and the foremost thing of the project is that
procurement of material such as aggregate, Binder, Blast
furnace Slag and waste materials as fillers.
 Preliminary laboratory test will be conducted as per
relevant code specifications.
 Next, development of warm mix asphalt mixture will be
conducted for the pothole gradation based on IRC: 116-
2014.
 The comparison between conventional WMA and WMA
with Blast Furnace slag and waste materials will be made
based on performance evaluation.
 At last, conclusions will be made for pothole patching with
optimum strength based on detailed resist analysis.
