Steps to measure the rate of Spray of Prime Coat in Road Construction are:
- You have to take sample tray of suitable size. I would prefer use tray of Size 35 cm * 28 cm.
- Weight the tray in weighing balance. Say initial weight of tray= A kg
- Place the tray over the road on which prime coat is to be sprayed and hence the prime coat is sprayed over the tray.
- Let the prime coat dry for some time and weight the tray over which prime coat is sprayed. Say Final weight of Tray(with the prime coat)= B kg
- Calculations to be done:
- Area of tray = 0.35 *0.28 =0.098 sq/m
- Initial Weight of Tray= A kg
- Final Weight of Tray= B kg
- Specific Gravity of Prime Coat= 0.95
- Calculate increase in Weight= (B-A) kg
- Rate of Spray in Kg = (Increase in Weight)/(Area of tray)
- Unit of Rate of Spray in kg/sqm.(Kilogram per square meter)

Lime stabilization with deep injection :
yes definitely it is possible that the embankment settlement can be reduced at embankment junction by lime stabilization with deep injection
The process of injecting a lime slurry into the subsurface up to some depth of some feet it is one of the innovative and comparatively very good technique for an engineer as well as for labour.
The main purpose of constructing climb up to some depth is to fill voids with a chemical compound
Thank you.

In OPC, the main alkali is cal. Hydroxides formed from limestone, the cal. Carbonate. The second material in OPC is silica in the form of sio2 and aluminate to some extent. This proportion of silica and alumina wrt ca(oh) 2 mainly decides the properties of cement.
When fly ash or any other substances like slag, rice husk ash, quartz, or feldspar (all contains silica) is added to some extent with OPC – the result is PPC. This PPC takes a long time to harden, the hydration at a considerable rate even continues for months together. But after a prolonged period, it achieves qualities like good waterproofing, weather resistance, and strength equal to or greater than that of OPC, with a lower cost than 100%OPC.
This unique quality of OPC, that it achieves 90 % of its strength in 28 days, makes it vulnerable to replace lime or every cementitious material.
So to achieve the equal or more strength than OPC with less cost – activation of today’s pozzolanic material, the coal fly ash, is mixed or activated with sodium hydroxide before it is acted with cal oxide/hydroxide. Experiments with diff. Percentage of activated fly ash has shown very encouraging results with a higher strength but not before three months curing. Research is going on with diff. percentage of silica and aluminate with sod. hydroxide to achieve quick strength.
In future this sod. hydroxide may replace the requirement of limestone completely for the making of cement.

- QZSS(QUASI-ZENITH SATELLITE SYSTEM). It is made by Japanese.
- BEIDOU(1 & 2) -it is a satellite navigation system of China.
- GALILEO– this is a European positioning system which is divided into three parts i.e space, ground, the user.
- GLONASS– it is a Russian version of the positioning system has five versions till now.

GPS (Global Positioning System) and GLONASS (Global Navigation Satellite System) are two systems of satellites with the primary objective to provide an accurate positioning in terms of latitude, longitude and altitude to any reciever on the planet surface.
GPS is a system launched and maintained by the US while GLONASS by Russia. GPS was launched four years earlier than GLONASS. The latter began production in the USSR days back in 1976 and was launched in 1982. GLONASS after being refueled in Vladimir Putin’s precidency has put up all 24 geostationary satellites required to provide complete coverage. GPS on the other hand was launched with 22 and now has 31. GPS is overall considered to have a better accuracy though GLONASS has a better accuracy as we go closer to the poles.
