What is the important of Proctor Compaction Test?
Can a slab over a trapezoidal cross drain with slope of 1:3 be placed and whether the slab will be stable for road
Sir, Basically slope morphology impacts road drainage and ultimately road stability. Therefore we can placed culvert in each draw. Side slope for rural road where embankment height is less than 3m should be 1:3

See lessHow to calculate admixture for transporting concrete for long distances to delay setting time in case of long-distance transportation in transit mixers?
The admixture which we use in the concrete for delaying its setting time then such type of admixtures are called as retarders. Gypsum is a retarding agent which we add in the cement during its manufacturing process. Gypsum is work as a starting agent as well as it restricts soundness in the cement.Read more

Apart from gypsum of various admixtures already listed in some previous post.
The chemical name of gypsum is calcium sulphate.
Thank you.

Difference between granular sub-base and wet mix macadam in payment structure: The wet mix macadam mostly consists of laying spreading and compacting of clean, crushed, well-graded granular material that is prepared and approved granular sub-base.

The wet mix macadam mostly consists of laying spreading and compacting of clean, crushed, well-graded granular material that is prepared and approved granular sub-base.
Single compacted wet mix macadam player shall not be less than 75mm.
Whenever we are using vibrating compacting equipment then compacted depth of a single layer of the course of the subway may be up to 200 mm.
Wet mix macadam shall be prepared in an approved of water macadam mixing plant.
Here replacing the aggregate fraction should be retained on 22.4 mm sieve with materials of passing from 22.4 and written on 4.75 mm.
While the addition of water, the evaporation loss shall be considered the mixed material shall be uniformly wet and segregation will take place.
See lessSir, Can we place column in the clear span of a beam without mid column support as shown in the figure. I was ...
Yes, you can do that. These are called hung columns. These are columns, having no foundation/ footing, rest over beams, or slabs. These are also termed as hanging columns/ floating column. They can not transfer load directly to the foundation or footing. Load from these columns is the point load onRead more

Meaning of Reinforced soil: Reinforced soil is simply a combination of compacted earth fill with the tensile reinforcement for creating an earth structure.
Advantages of reinforced soil:
- Less quantity of earth fill is required.
- The construction can be directly done on the soft ground.
- The structures can be quickly built as compared to any other conventional methods.
Limitations of reinforced soil:
- One of the biggest doubts about reinforcing soil is its durability.
Thank You.

You can use Self Compacted Concrete to use for narrow columns. It also used where the reinforcement is heavy and process of compaction is not available/difficult to compact.

See lessWhy Back Sight is also called as Plus Sight?
Back Sight: Backsight is simply a first reading which is taken after setting up the instrument. Why the backsight is also called plus sight: Only because the reading is taken of known elevation to continue taking foresight reading. Thank You.

Compaction test of soil is carried out using Proctor’s test for understanding the compaction characteristics of different soils with change in moisture content. The ability for compacting a soil depends on the water content of the soil. Thus, water acts as a lubricant between the soil grains however as its content increases the water may occupy the entire pores. Since it is relatively incompressible in comparison to the air it may restrict compaction. Proctor compaction test is used to determine the optimum moisture content during compaction which gives the greatest soil density.
