Abstract
The engines of economic growth depend on good infrastructural facilities, as good roads are the life line of country to
meet ever increasing demand of users. In India, the sustained efforts need to be made with respect to quality and
quantity of roads in terms of load carrying capacity; performance of pavement, durability, length and economy is
needed. The construction of roads using hot mix asphalt increases pollution, hence the dire need to come out with a
fruitful solution is utilizing warm mix asphalt which is a fast emerging new technology and has potential to reduce
the energy consumption i.e. lowering the mixing and compaction temperatures. Warm mix asphalt can reduce
production temperatures by about 30º C to 40º C. Hot mix asphalt mixtures are generally prepared at 160°C or
greater temperatures depending mainly on the type of binder used. Study of literature shows very few experimental
laboratory research done in the area of warm mix asphalt technologies. In this study, an attempt is made to evaluate
the changes in engineering properties of the CRMB 60 with and without warm mix adhesion (zycotherm). Also
Marshall Mix design is carried out on CRMB 60 with and without warm mix adhesion in suitable dosages of 0.125%
and 0.15% at lower temperature as per the provisions of codal practice, without any compromise with quality. The
impression of tests proposes the powerful urge to move WMA into the standard of clearing items as the creation
temperature is brought down profiting the asphalt development proficiency and bringing down pollution levels as
well.
Keywords: Zycotherm, Marshall Stability, warm mix asphalt, Hot mix asphalt, CRMB 60.
1. Introduction
1
Warm Mix Asphalt (WMA) is a quick rising new
innovation which has a capability of upsetting the
creation of black-top mixtures. Expanding concerns on
environment, rising vitality costs, a worldwide
temperature alteration, and nursery impact, coupled
with expanded development costs prompted the
advancement of new advancements by the Asphalt
business to create Asphalt Concrete (AC) asphalts.
Broad examination is being carried out to assess the
effect and execution of these new innovations. Warm
blend added substances specifically Zycotherm
measurements in 0.125% and 0.15% is utilized with
CRMB 60 to lessen the blending and compaction
temperature is a sensible, temperate way to deal with
meet execution standard for asphalt today. The
innovation can decrease creation temperatures by as
much as 30 percent, this will diminish fuel utilization
by no less than 20% and essentially lower discharges
at the hot-blend plant as well as at the clearing site, yet

it delays the administration life of the road by
enhancing the execution and sturdiness of the bitumen
asphalt down, and compaction of asphalt mixes at
significantly lower temperatures compared to Hot Mix
Asphalt (HMA).
2. Literature Review
Rohith N. & J.Ranjitha (2013) uncovered that The
Warm Mix Asphalts (WMA) is adjusted Hot Mix Asphalt
(HMA) which is delivered, laid and compacted in
temperature which is lower than traditional HMA. The
WMA is created by blending synthetic added
substances to the ordinary blend to enhance the
asphalt execution. In this study an endeavor is made to
compare the Marshall properties of WMA created with
the concoction added substance: ZycoTherm and HMA
for Dense Bituminous Macadam (DBM) Grade 2. The
received blending temperatures for HMA was
155°C,130°C and 115°C and the blending temperatures
for WMA was 130°C and 115°C, with an added
substance measurement rate of 0.1% by weight of the
cover. The ideal fastener substance was to be figured
out exclusively for the mixture for diverse blending
temperatures and added substance measurements
