4.3.2 Mechanized Piling To compute piling time, when a rake or angled shearing blade is used, an equation to calculate the piling time per hectare, Tp, is Tp = (1/60) (B + M1N1 + M2N2 + M3N3 + M4N4 + DF) where the variables are defined as above. Table 4.2 shows the coefficients for piling when stumps have not been removed. TABLE 4.2. Production factors for piling in windrows. Tractor Factors Diameter Range, cm Min per cm of diameter for trees GHP 30-60 61-90 91-120 121-180 > 180 cm B M1 M2 M3 M4 F 140 185 0.6 1.2 5.0 - - 200 135 0.4 0.7 2.7 5.4 - 335 111 0.1 0.5 1.8 3.6 0.03 460 97 0.08 0.1 1.2 2.1 0.01 When piling is to include piling of stumps, increase the total piling time by 25 percent. EXAMPLE: Five hectares per km of right-of-way in hardwoods are being cleared for a road (extra width is being used to help the road dry after rains). Of the five hectares, 1.2 hectares per km will need to have the stumps removed. Tractor machine rate is $80 per hour. All material will be piled for burning. Work is being done by a 335 HP bulldozer. The average number of trees per hectare less than 180 cm diameter are in Table 4.3. There is also one tree per hectare with a diameter of approximately 185 cm. TABLE 4.3 Data for clearing, grubbing and piling example. Number of trees Diameter Range, cm Sum of tree diameters for trees <30 cm 30-60 61-90 91-120 121-180 > 180 cm N1 N2 N3 N4 D 1100 35 6 6 4 185 Tc = (X/60) (AB + M1N1 + M2N2 + M3N3 + M4N4 + DF) Tc = (1.3/60) [(1) (45) + (.2) (35) + (1.3) (6) + (2.2) (6) + (6) (4) + (185) (0.06)] = 2.34 hr/ha Tp = (1/60) (B + M1N1 + M2N2 + M3N3 + M4N4 + DF) Tp = (1/60) [111 + (.1) (35) + (.5) (6) + (1.8) (6) + (3.6) (4) + (185) (0.03) ] = 2.47 hr/ha Total tractor time/km = 3.8 (2.34 + 2.47) + 1.2(1.25) (2.34 + 2.47) = 25.5 hr/km P = 1/25.5 = .039 km/hrUC = 80 25.5 = $ 2039/km4.4 Earthwork The earthwork cost is calculated by estimating the number of cubic meters of common material and rock which must be moved to construct the road. The earthwork production rate is calculated as the cubic meters per hour which can be excavated and placed divided by the number of cubic meters per km to be excavated. Road construction superintendents can often estimate the number of meters per hour that their equipment can build road based upon local experience after looking at the topography. The engineer's method is to calculate the number of cubic meters to be excavated using formulas or tables for calculating earthwork quantities as a function of sideslope, road width, cut and fill slope ratios. Production rates for bulldozers and hydraulic excavators are available. For example, a 6.0 meter subgrade on a 30 percent slope with a 1.5:1 fill slope and 0.5:1 cut slope with a one foot ditch and a 20 percent shrinkage factor would be approximately 2100 bank cubic meters per km for a balanced section. An average production rate in common material (no rock) from an equipment performance handbook might be 150 bank cubic meters per hour for a 300 hp power-shift tractor with ripper. The tractor cost is $80/hr. The rate of excavation would be P = (150 m3/hr)/(2100 m3/km) = .07 km/hr UC = 80/.07 = $1143/km If the earthwork is not being placed or sidecast within 50 meters of the cut, the production rate for pushing the material to the placement location must be made. Scrapers or excavators and dump trucks may be used. Excavation rates in rock vary with the size of job, hardness of rock and other local conditions. Often there is a local market price for blasting. Estimates of blasting production can be made by knowing the size of equipment and the type of job. For example, a 10 cm track-mounted drill and 25 cubic meter per minute air-compressor may prepare 40 cubic meters per hour for small, shallow blasts and 140 cubic meters per hour for larger, deeper blasts including quarry development to produce rock surfacing. A major cost will be explosives. For example, 0.8 kg of explosive such as Tovex might be used per cubic meter of rock at a cost of approximately $2 per kg.4.5 Finish Grading Finish grading of the subgrade can be estimated by determining the number of passes a grader must make for a certain width subgrade and the speed of the grader. This number can be converted to the number of hours per hectare of subgrade. For example, a 120 hp grader may require about 10 hours of productive machine time without delays per hectare of subgrade or 0.1 hectares per hour. The production rate for final grading of a 6.0 meter subgrade would then be, P = (0.1 ha/hr)/(0.6 ha/km) = .17 km/hr If the grader cost is $30/hr, the unit cost of grading is UC = 30/.17 = $176/km Similarly, the rate of pulling ditches per kilometer can be estimated.4.6 Surfacing Surfacing costs are a function of the type of surfacing material, the quantity of surfacing material per square meter, and the length of haul. Local information is the best guide in constructing surfacing costs due to the wide range of conditions that can be encountered. Natural gravel from streams may require only loading with front-end loaders directly to dump trucks, transporting, spreading, and may or may not be compacted. Laterite may be ripped by crawler tractor, loaded by front-end loader, transported, spread and grid-rolled with a sheeps-foot roller to produce a sealed running surface. Rock may have to be blasted, loaded into one or more crusher(s), stockpiled, reloaded, transported, spread, and compacted. The costs for each of these operations can be developed by estimating the equipment production rates and machine rates. EXAMPLE: A relatively complex surfacing operation requires developing a 20,000 cubic meter solid rock source (26,400 cubic meters in the road prism) to surface 26.4 km of road including shooting and crushing rock, loading, transporting, and spreading rock as follows. To open up rock source, use data from clearing and common excavation: (a) To clear and excavate to rock: Equipment Machine Hours Machine Rate Cost Tractor 27 72.00 1944.00 Cost per cubic meter solid rock = $0.10 (b) To drill and blast at a production rate of 140 cubic meters per hour Equipment Machine Hours Machine Rate Cost Drills 1.0 60.00 60.00 Compressor 1.0 55.00 55.00 Explosives 0.8 kg $2.0/kg 140 m3 224.00 339.00 Cost per cubic meter solid rock = $2.42 (c) To crush 225 tons per hour (2.6 tons/solid cubic meter): Equipment Machine Hours Machine Rate Cost Tractor 0.5 72.00 36.00 Loader 1.0 90.00 90.00 Crusher 1.0 90.00 90.00 Stacker 1.0 15.00 15.00 Generator 1.0 20.00 20.00 251.00 Cost per cubic meter solid rock = $2.90 (d) To load, transport, spread 20,000 cubic meters of rock. 1 truck 3 loads/hr 20 tons/ld m3/2.6 ton = 23 m3/hr If 4 trucks are used: Equipment Machine Hours Machine Rate Cost 4 trucks 870 50.00 43,500 Loader 218 90.00 19,600 Tractor 218 72.00 15,700 Grader 30 60.00 1,800 80,600 Cost per cubic meter solid rock = $4.03 The total unit cost of per cubic meter of rock spread on the road is Activity $/m3solid $/m3prism $/km Develop pit 0.10 0.08 74 Drill and blast 2.42 1.83 1833 Crush 2.90 2.20 2197 Load, transport, and spread 4.03 3.05 3053 9.45 7.16 7157 Equipment balancing plays an important role in obtaining the minimum cost per cubic meter for surfacing. In some areas, market prices for various types of surfacing may exist and tradeoffs between aggregate cost, aggregate quality, and hauling distance will have to be evaluated. Since surfacing is often expensive, a surveying crew is sometimes added to stake and monitor the surfacing operation.4.7 Drainage Drainage costs vary widely with the type of drainage being installed. The costs of drainage dips (water bars), culverts, and bridges are often expressed as a cost per lineal foot which can then be easily applied in road estimating. Local values for cost per lineal foot for culverts and different types of bridges are generally available. If not, constructed costs can be made by using time study data. EXAMPLE: A 45 cm culvert, 10 meters long, is being installed. Experience indicates that a small backhoe and operator, and two laborers can install 3 culverts per day. The culvert crew uses a flat-bed truck to transport themselves and the pipe each day. To install 3 culverts: Equipment Machine Hours Machine Rate Cost Backhoe 6 60.00 360.00 Truck 9 12.00 108.88 Pipe Cost 30 meters $15/meter 450.00 918.00 Cost per lineal meter of culvert = $30.60 per meter Alternatively the cost could be stated as $306 per culvert or if there were an average of 4 culverts per km, then $1224 per km

Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other
