Soil Compaction Test

Soil compaction is the major area of geotechnical engineering. Soil is composed of multiple pores present on its surface, while the soil is mainly composed of gravel, sand, rocks, etc. The arrangement of these rocks and gravels is such that they build up voids (spaces) between them, which allows spaces for the roots of the plants and crops to spread and absorb the required amount of nutrients. Soil compaction is a major problem primarily caused by human activities, micro-organisms, and other multiple factors.

Question

5. Estimate the cost of compacting 3700 CCM using a roller compactor based on the following information:
The number of passes required = 10
Width compacted per pass = 2m
Compactor speed = 7km/h
Compacted lift thickness = 0.3m
Job efficiency = 55min/h
Cost per hour = $150

Expert Solution

Step 1: Given data

compacted volume=3700 m³

compacted thickness=0.3m

width of compacted per pass=2m

compactor speed=7kmph

job efficiency=55min/hr

cost per hour=150$

number of passes required=

Aggregates from a material storage site are required for the embankment of a roadway. The porosity of the aggregates at the storage is 75% and it is desired that these be compacted until a porosity of 20% is reached. The section of current interest for the embankment is 8m wide, 1.2m compacted thickness and 220m long. Compute the total cost if each truckload of aggregates to be transported will cost around 3550.00 and each truckload has a capacity of 7m3.
