What is the CBR value for sub grade in rigid pavement road construction?
-
Rigid pavements because of their nature, allow for a larger variation in subgrade material (in terms of strength), unlike flexible pavements. That is why rigid pavements can be built over almost any kind of soils with appropriate ground improvement. The general range for CBR is 2% to 14% or 15%. IfRead more
Rigid pavements because of their nature, allow for a larger variation in subgrade material (in terms of strength), unlike flexible pavements. That is why rigid pavements can be built over almost any kind of soils with appropriate ground improvement.
The general range for CBR is 2% to 14% or 15%. If it is found below 6%, then the code specifies some necessary subgrade improvement before laying the concrete slab directly over it.
Also, the CBR could be increased up to say 40% or 50% by ground improvement, and still, the subgrade may be fit for rigid pavements.

River sand M sand Shape is round & smooth Shape is cubical, angular & rough texture Less cement paste is reqd to make concrete Req’s more water & cement Sand has high cost but using it makes work economical Sand is cheaper but using it will make it increased cost Contains less microfine particles Contains more microfine particles Doesn’t affect any property, best choice Affects strength & workability of cocrete Moisture content present Less or no moisture content Strength is less High comp strength & flexural strength but should be well graded. Slit & over-sized materials& marine products present should be removed by washing & screening. No slit & over-sized materials & marine products Used for RCC, plastering & Brick or block laying work Diff grades is used for diff works.

can we consider drum mixing of concrete same as batch mix or nominal mix?
-
Yes. Of course. The method of mixing is not relevant to batching. So long as the quantities and proportions remain what they need to be, drum mixing or hand mixing, both are batch mixing. In fact, in the industry, mostly drums are used for mixing concrete because they save time and labour.

If the slump test fails for concrete then immediately reject that concrete because high amount of water can decrease the durability of the concrete. But dont add water if the slump test fails.
