Augmented Reality (AR) emerges as a pivotal tool in the landscape of civil engineering, offering a multitude of benefits alongside notable considerations. By seamlessly blending digital information with the physical environment, AR has redefined how engineers conceptualize, plan, and execute infrastructure projects.
The capacity of AR to provide real-time contextual information directly within the field has streamlined construction processes, enhanced design visualization, and improved stakeholder engagement. Through AR-enhanced project planning, engineers can mitigate errors, optimize workflows, and foster collaboration among teams, ultimately leading to more efficient and cost-effective project outcomes.
However, it is imperative to acknowledge the challenges associated with AR adoption, including initial investment costs, technological limitations, and concerns regarding data security and privacy. Despite these hurdles, the potential of AR to revolutionize civil engineering practices cannot be overstated.
As AR technology continues to evolve and become more accessible, its integration into civil engineering workflows will likely become more commonplace. By embracing AR with careful consideration of its benefits and limitations, engineers can harness its transformative power to drive innovation, sustainability, and progress in infrastructure development for years to come.

3. INTRODUCTION
• Under PMGSY, the rural road network has experienced a considerable
growth. The good quality roads being constructed, immensely contribute in
the progress of the country.
• Quite often these roads get damaged due to overloaded vehicles, inadequate
drainage facility and water logging problems.
• The technology developed by IIT KHARAGPUR, known as CELL FILLED
PAVEMENT, has proved to be very promising solution for this issue. It
provides long lasting concrete pavement at low initial cost which are almost
maintenance free.
• Cell-filled concrete pavement is made up of a plastic cell formwork that is
poured over a compacted subgrade or sub-base and filled with concrete or
stones .
4. LITERATURE REVIEW
• Structural Evaluation of Self Filled Concrete Pavement Sahoo (2018) - Constructed
250 meter long PCCP pavement over 150 mm compacted thickness of moorum sub-base
to test its feasibility on field for low volume roads.
• The premixed cement concrete mix used for filling the pockets of plastic cell was mixed
in the proportion 1:1.5:3 (cement: fine aggregate: coarse aggregate) by volume.
• The result obtained from the investigation showed that the elastic modulus of cell filled
concrete layer were in the range 2486 to 6850 MPa and that of foundation layer (sub-base
and sub-grade) were in the range 123 to 161 MPa which are sufficiently high for low
volume roads.
5. PLASTIC CELLS
• plastic cells can be made from reclaimed high density
polythylene (HDPE) sheets of thickness 0.22mm to about
0.25mm.
• Plastic sheet manufacturers can supply rolls of strips 50mm
to 100mm wide depending upon the depth requiremnt.
• Waste low density polyethylene(LDPE) is available in plenty
and the recycled LDPE sheets of thickness 0.3.to 0.35 mm
can be used for making the formwork of cells.
• Readymade formwork of cells also can be obtained from the
market.
• Iron spikes of about 200mm long are used to keep the cell
walls taut.
