Highway Research Record No. 39 - Indian Roads Congress

progress: Govt. of Gujarat has instructed this office
for extension of this scheme with laboratory study
using more samples from other regions of Gujarat.
Accordingly the testing of samples from all the regions
was completed. Evaluation and analysis of testing part
and report are under progress.

2. Zycosoil Nanotechnology Application in Leh
Road, BRO
Date of Start: March 2011
Date of Completion: April 2012
M/s Zydex Industries, Vadodara, Gujarat
present Status and progress
Status: Ongoing/Completed: On-going continued
long term evaluation
Year of Last Report: Year 2011
progress: One post snowfall evaluation completed
Scope and objectives
Zycosoil additive mixed with hot asphalt binder for
improving asphalt-aggregate bonding, eliminating
moisture sensitivity (anti-stripping) and to improve
compaction and workability.
Methodology
Zycosoil added in hot asphalt binder @ 0.15% by weight
of binder and mixed thoroughly with circulating pump.
The hot modified asphalt binder (VG 10) was mixed
with heated aggregates in drum mix plant at site.
Significance / Utilisation potential
•
•
•
•
laying and compaction of asphalt concrete was
found to be better and no sticking was observed on
the compactor’s roller. It took 4 passes as against
8 passes in conventional material, for same amount
of compaction.
Asphalt coating on aggregates found to be a very
uniform coating and mixture was found shiny.
Field lab test report:
Stripping value at 0.1 Per cent to 0.15 Per cent
dosage was found 90 to 100 Per cent.
ROAD RESEARCH IN INDIA 2011-12 13
• Better bonding
and improved stability laboratory
test samples of Zycosoil mixed asphalt – concrete
mixture.
•
Zycosoil mixed easily in hot melted asphalt tank.
Further findings / supporting data
The site visit was observed in May 2012. The surface
was found in good condition without potholes or
cracks.

3. Zycosoil Nanotechnology in Road
Construction
Date of Start: March 2012
Date of Completion (Actual): April 2012
Zydex Industries, Vadodara, Gujarat
Present Status and Progress
Status: Completed
Year of Last Report: 2012
progress: First monsoon observation and evaluation
done
Methodology
Terrasil solution [ratio 1:500 (Terrasil : water)] applied
over WBM/ stone base and left to dry for 30 minutes.
Cationic bitumen emulsion SS 1 mixed with Terrasil
solution (Terrasil: water: SS1 emulsion ratio 1:400:100)
and sprayed @ 2 ltr/sqm. It was observed that the prime
coated surface dried within 30-45 minutes.
Zycosoil modified Tack coat applied over dried prime
coat surface (Hot tack-coat grade 60/70 using Zycosoil
@ 0.1 Per cent by weight of bitumen) followed with chip
carpeting done.
Sealcoat done using Zycosoil @ 0.1 Per cent by weight
of bitumen binder.
Significance / Utilization potential
i. Faster setting time for Prime coat to enable
immediate tack coat application and asphalt
layers on the same day as well road can be
opened to traffic immediately.
ii. Protection against infiltration of water through the
bituminous layer.
