Road construction work training. At Rajasthan ajmer.

1. Summer internship at
patel infrastructure
Duration: 2/6/2019 to 15/6/2019
Site Location :- sathana (kgbot 2)
ajmer rajasthan

2. Base camp

3. Date 3rd to 7th June
• 5 days were allocated for understanding laboratory
experiment.
• Ongoing experiment were explained by engineers in
working hours.
• Mainly for concrete, aggregate, soil, and bitumen

4. Soil tests
• Grain size analysis text
• Proctor compaction test
• California bearing ratio test
• As property of soil changes by different locations tests
were carried for that portion
• And for each location optimum moisture content and
maximum dry density is find out

6. Concrete and aggregate test
• For concrete : compression test were carried out and for
aggregate impact test is carried out
• Cubes were casted at working site and bring to laboratory for
curing and to test at 3, 7, & 28 days
• At time of testing senior engineers come for verification of
strength of cube

7. Bitumen test
• At time of internship we learned DBM (Dense bitumen
macadam) test and grain size analysis test for bitumen
• From DBM test we can find out optimum bitumen content

8. From 8th to 12th June
• Next 5 days we went for on site road construction it was
of widening of existing road
• At site leveling of original ground level is done by auto
level instrument
• Site engineer explained how to do surveying and
levelling and to how to use the instrument .
• And earthwork is carried out

9. GSB layer
• After the Earth Work the Sub-Base of the road is
constructed with Granular sub-base (GSB) and
compacted in layers not exceeding 100mm.

10. WBM Base-Course
• Once the Sub-Base is prepared, the base course is required to
provide the strength to the road.
• Generally, the base course is constructed with the help of stone
metal and other suitable materials.

11. WBM Base-Course
Water Bound Macadam (WBM) base course is constructed with graded aggregate
in two or three layers as per the design. Thereafter, binding material is applied
and sprinkling of water is repeated

12. From 13th to 15th june
• Last 3 days we went for observation of bridge construction
• At site construction of bridge girder is done.
• Placing of reinforcement and form work was carried out that
time.
