Question

1- Indicate total resistance equation and explain constituents?

2- What is a good efficiency factor for a front shovel working on a highway construction project?

3- Sketch typical compaction specification diagram and indicate optimum range?

please write it clearly.

Answer 1

1- question not stated correctly from which field. resistance equation for???

2- Efficiency factor depends upon:-

• Type of the shovel blade and the strata of soil.
• The length of the stretch and working time.
• The efficiency of the shovel operator
• The condition of the equipment
• layout of the highway.
• climatic conditions.

3- The optimum range depends upon the type of the soil and the compaction equipment to be used, for lab tests this can be found out in soil mechanics
