The second series of performance observation on
various road sections laid with Stone Matrix Asphalt
(SMA), Hot Mix Asphalt mixes using Waste Plastic and
Microsurfacing were undertaken during November/
December, 2011. Further work with regard to processing
/ analysis of 2 nd series of performance data is in progress
and third series of periodic observations are being
planned to be undertaken in the month of November
/ December 2012. Performance observations being
taken for time series data include (i) Assessment of
Pavement Surface Distress by visual observation (ii)
Measurement of Pavement surface roughness by
using Roughometer-II (iii) Deflection measurements by
using Benkelman Beam Method and (iv) Traffic volume
survey, 24 hours round the clock.
Further Findings/Conclusions/Supporting Data
Time series data collected for the two series of
observations reveal that pavement surface distress
and riding quality of test sections has not changed
significantly.

4. Zycosoil Nanotechnology Multilayer
Waterproofing Treatment of Soil and Asphalt
Concrete in Road Construction
Date of Start: March 2010
Date of Completion (Actual): June 2010
Zydex Industries, Vadodara, Gujarat
present Status and progress
Status: On-going continued long term evaluation
Year of Last Report: Year 2011
progress: Two post monsoon evaluations completed
Methodology
Soil base
Zycosoil (new name Terrasil for soil application) applied
on the compacted soil layers for making waterproofed
vapour permeable layer.
WBM / Carpet layer
Prime / Tack coat using Zycosoil (new name Terrasil)
solution with cationic bitumen emulsion and sprayed on
WBM/ Carpet layer for improved wetting, penetration,
bonding and quick set.
Asphalt layer
Zycosoil added in hot asphalt binder @ 0.1 Per cent by
weight of binder and mixed thoroughly with circulating
