SUMMARY OF THE SECOND CHAPTER : SOIL TESTS FOR HIGHWAY PURPOSES

Soil engineering is vital within civil engineering. The properties of a soil influence and affect a structure when being built and as a result the soil must be tested before designing

We end this chapter of "soil tests for highway purposes" with our 8 posted tests , and our next stop is " Mix Design of Concrete ACI 211"

As the drum rotates , a shelf plate picks up the sample and the steel spheres, carrying them around until they are dropped to the opposite side of the drum,causing an impact-crushing effect.The contents then roll withi the drum with an abrading and grinding action until the shelf plate impacts and the cycle is repeated.After the prescribes number of revolutions,the contents are removed from the drum and the aggregate portion is sieved to measure the degradation as percent loss.
