Utilization of construction equipment:
In our projects construction equipments have been used intermittently,
utilization of output can be judged using the time and ratio of
equipment use as an index. However, there in few projects which
provided concrete data which on the demand and analyzed by us. As
exercised out put ratio is seven of the ten schemes is reported that
construction equipment was used sufficiently and appropriately.
1. Floor Saw & Diamond Blade (cutting of the asphalt surfacing)
2. Compressor & Tools (Surfacing & scabbling)
3. Pan type mixer (mixing, screed & transition strip
4. Heavy duty drill (drilling holes for anchors)
5. Small drill (fixing the anchors)
6. Selection of small hand tools
7. Minimum 8kva Generator
All tools are depend on project

SBR Latex Polymer for Bounding And Strength
Today's increasing loads, greater traffic volume and the need for better, longer-
lasting roads demand better service from paving materials. Asphalts modified with
SBR Latex Polymers offer the best method of improving binders for highway, street
and airport paving and maintenance projects. SBR Latex Polymers were created
specifically for modifying asphalt binders. SBR easily blends with the asphalt to
form a homogenous reinforced composite.
SBR Polymers provide:
Optimized visco-elastic properties
Increased resistance to rutting and shoving
Increased resistance to low temperature cracking
Increased resistance to load-associated fatigue cracking
Reduced temperature susceptibility
Reduced reflective cracking
Minimized aging effects
Reduced stripping and raveling

and other heavy structure.
Lifting Jacks for Change Bridge Bearing Pads
Bridge maintenance is undertaken to extend the life of the structure and to ensure that it
functions as designed, thus ensuring public safety. This Operational Statement applies
only to: deck sweeping and washing to remove traction material (e.g., sand and salt
residue), cleaning of all bridge components (substructure, superstructure and deck), the
removal and application of protective coatings, deck wearing surface replacement, the
removal of debris to protect piers and abutments, and structural repairs involving no
Aims of maintenance plan:
• Maintain safe passage for bridge way users.
• Protect the asset value of the bridges.
• Ensure consistent standards of maintenance across relative to road usage.
• Ensure expeditious movement of traffic by complying with the Traffic Management
• Facilitate technical and financial monitoring in order to establish trends in Bridge
• Provide a framework for reviewing policies and standards and for developing
• Implement the principles outlined in the Code of Practice for Maintenance
Concrete repair replaces defective, damaged, or deteriorated concrete;
restores structural function; protects the surface or underlying concrete from
aggressive environments; and restores any lost performance requirements.
Concrete repair problems are diverse in nature. Each condition requires a
clear understanding of what is expected of the repair including appearance,
protection needs, and load carrying requirements.
Critical to successful concrete repair is
proper surface preparation of the area being
repaired. This includes complete removal of
concrete around and below the reinforcing
steel and preparation of the substrate.
Combined, these techniques ensure
maximum bond between the new repair
material and the existing substrate, resulting
in effective, long-lasting repairs.
An effective repair strategy must draw from
a variety of repair materials, each having an
installation technique that best suits both
the material and the strategy.
At Structural Preservation Systems, we have
the expertise to utilize specialized
techniques applicable to surface repair
Expansion Joint Fixing
Whether you're fixing of expansion joint material, the application method for repair is
always the same. Expansion joints are an integral part of concrete structures. They
are built into deck systems to control the stresses of volume changes in concrete.
Depending on the type of construction (cast-in-place, precast, etc.), joints are
installed to isolate ramps, buildings, and large expanses of deck surface. They may
also be needed to provide free rotation of deflecting members. Most joints open and
close according to daily and seasonal fluctuations in deck surface temperatures.
Joints provide a natural place for water, salts, and debris to collect. They also
present a hazard to pedestrians who may trip over them. To prevent these
problems, joint seals can be installed. Seals must be designed for the intended
movement of the joint, as well as for water tightness, wheel action (traffic,
equipment), pedestrian safety, and reparability.
We construct broadly encompasses the issues relevant to the process of road
construction and maintenance, including the design, contracting, implementation,
supervision, and maintenance of roads and related structures, such as bridges and
Road Safety Paints:
The light emitting paint is nonconventional source of energy. The light emission is
guaranteed lifelong. These paint may be termed as illumination source with least
installation cost, no operating cost & maintenance free. It is absolutely safe,
nonradioactive & nontoxic.
Other than Paints, Inks, Vinyls & Color
Transfers we also undertake job work of road
marking, lane marking & zone marking for
indoor & outdoor areas. We also offer signage
& hoardings as per customer's specification.
We have our infrastructure with digital cutters,
fabrication & paint shop.
Light Emitting Paint for Road
We offer light emitting paint for road. There is great scope
for this paint in infrastructure projects like road, highways,
express highways, bridges, tunnels, etc. Quiet high number
of accidents takes place due to poor lighting. The present
hot melt plastics & fluorescent paints used for lane marking
and road marking are visible only when light fall on it in a
particular angle. Whereas light emitting paints offer great
visibility in the dark. It avoids many of mishaps and
accidents. Also the the fluorescent paint looses its luster
within short period.
On the contrary light emitting paints offers illumination for long period. The lane marking
strips, zebra crossings, direction indicator arrows, STOP signs at signal are being
painted with light emitting paints. The anti crash barriers installed at sides of the
highways are painted with black & white strips of light emitting paints, adding safety in
the dark too. Various curves & obstacle at ghat sections & hilly terrains can be easily
indicated in dark with light emitting paints. All these infrastructure projects spend huge
expenditure on street lighting for installation, maintenance & operating cost. Light
emitting paints is maintenance free solution with no operating cost & minimum expense
on installation. Street lights operated by photoelectric switches often malfunction in urban
areas causing collision of vehicles against dividers, side railing, pillars & post.
We trust that the above reporting on the status of the
recommendations is useful, and are pleased to see that most of
the recommendations of its initial report are part of current
operations, as reflected in its strategic planning process and
implementation through its operational plan. We believes that as
work with the collaborated organizations reaches finalization, the
continuing long-term operational stability of the organization is
an important part of ensuring its successful global responsibility.
