For example a mix containing 189 -inch NMS stone should be placed at a compacted depth of at least 1- 189 to 2 inch If a 189 -inch top-size mix is placed at 1 inch compacted depth the mat may pull and tear and the stones may be broken by the rollers Thus the depth of paving does influence the ability to obtain proper compaction...

The aggregate with rounded shape has the minimum percentage of voids ranging from 32 to 33 It gives minimum ratio of surface area to given volume and hence requires minimum water for lubrication It gives good workability for the given amount of water and hence needs less cement for a given water cement ratio...

Aug 09 2016 0183 32 We think fine soil particles are so fine and are packed closely so they should have less void ratio but in actual things are not always the same the way we look at it In actual fine grained soil have more void ratio as compared to the coarse g...
