Embankment fill is to be compacted at a density of 18KN/m. The soil of the borrow area is at a density of 15KN/m. What is the estimated no of trips of 6m³ capacity truck for hauling the soil required for compacting 100m³ fill of the embankment? (Assume that the soil in the borrow area and that in the embankment are at same moisture content)

Embankment is to be built with 15 km length of proposed road with 2 m height of road embankment. The cross sectional area of embankment and distance of borrow pit from embankment are 30 m² and 10 km respectively. Soil is to be compacted to 97 % of the max dry density. Information given as follows: (a) Results from laboratory compaction test: Max dry density-1.80 Mg/m³ Optimum water content=12% (b) Borrow material: Dry density-1.70 Mg/m² Water content-8% Calculate volume of additional water required for the entire volume of the embankment Final answer should be = 27, 486 m³
A truck is hauling earth from a construction site. The truck has the following specifications: Maximum allowable gross vehicle weight 37,800 lb Empty vehicle weight 10,800 lb Heaped capacity 12 yd 10 yd Struck capacity Haul time to dump area, including load, haul, return, and dump times 17 min Delay time 5 min/hr The soil has the following characteristics: Bank density Loose density 110 pcf 100 pcf The productivity, in bank measure (yd/hr), of this operation is most nearly: 38.8 (В) (C) (D) 35.3 32.3 29.5
Question 1: Earth whose in situ weight is 112 pcf, whose loose weight is 95 pcf and whose compacted weight is 120 pcf is placed in a fill at the rate of 250 cy/hr, measured as compacted earth. The thickness of the compacted layers is 6 inch. A compactor with a roller drum width of 84 inch is used to compact the material at a speed of 3.5 mph. Assume a 55 min hour operating efficiency. Determine the number of rollers required to provide the necessary compaction rate if eight drum passes are specified for each layer of earth. O 1 Roller O 3 Rollers O O Roller O 2 Rollers
In natural state, a soil weighs 3500 lb/cy. The same soil has a load factor of 0.83. a. What is the unit weight of the soil in its loose state? b. A contractor has seven (7) Caterpillar 725 articulating trucks available to haul this same soil to a project that requires 55,000 ccy of the soil. In the compacted state, the soil weighs 4300 lb/cy. Each Caterpillar 725 has a maximum haul capacity of 17 lcy. Currently the project schedule only accounts for each truck hauling no more than 550 loads to the site. Based on the maximum capacity of the Caterpillar 725, can this schedule requirement be met?
(a) Distinguish between consolidation and compaction. What similar result do the two processes have on a soil mass! لما
Two scrapers will deliver to the project 650 LCM per hour of fill material. The rolling width of the roller is 1.2m. 6 passes at 4 km/hr are required to obtain the required density. The fill material will be placed in 0.3m compacted lifts. Load factor (LF) = 0.8 and shrinkage factor = 0.85. Assume a 50-min job efficiency, determine the number of rollers required to support the scraper operation.
Q1. Discuss the following regarding compaction and consolidation a. Results of both b. Difference between both c. can compaction of earth be achieved by cosolidation? why/why not?
Earth-whose in situ weight is 112 lb/cf, whose loose weight is 95 lb/cf, and whose compacted weight is 120 lb/cf-is placed in a fill at the rate of 250 cy/hr, measured as compacted earth. The thickness of the compacted layers is 6 in. A compactor with a roller drum width of 84 in. is used to compact the material at a speed of 2.5 mph. Assume a 55-min hour operating efficiency. Determine the number of rollers required to provide the necessary compaction rate if eight drum passes are specified for each layer of earth.
6. It is required to transport a soil from a source location to the construction site. The specific gravity of the soil is 2.65 and the water content is measured as 10%. The capacity of the trucks, that will be used to transport the soil, is 20,000 kg. If the volume of soil placed in each truck is 9m³, what should be the minimum void ratio so the capacity of the truck is not exceeded.

QI/ A contractor excavates 10,000 m soil at moist unit weight of 17.5 kN/m' and moisture content of 10% from a borrow pit and transports it to a project site. The project has an area of 20,000 m2 to be filled with this compacted soil. If the required dry unit weight and moisture content of the compacted soil are 18.3 kN/m and 12.5% (assume there is no soil loss during transportation and compaction), what is the thickness of the compacted soil and how much water needs to be added?
