The size of riprap to use for a given stream depends on the velocity of the water when the stream is at a bank full stage. Table 1 provides minimum size ranges for given stream flow veloci ties. 1. Reshape the streambank to a maxi mum slope of two feet of horizontal distance for one foot of vertical rise.

3/4" 2" CLEAN CRUSHED ANGULAR STONE 6" 2 • Backfill material used for embedment/anchoring and for surrounding areas will be ¾"2" particle size, clean, crushed angular stone. • Placement of backfill material for embedment and surrounding areas is best accomplished by using the long reach of an excavator or stone shooter/ conveyor system.
than rocks of a uniform size. Rock riprap sizes are specified by either weight or diameter. Stone should be hard, angular, weatherresistant; specific gravity at least Gradation: wellgraded stone, 50% by weight larger than the specified "150" The largest stones should not exceed .
1 m3 = – of crushed stone depending on the grading and degree of compaction. tonnes of Type 1 = 1m3; 1m3 of well compacted scalpings is heavier than 1m3 of 75mm clean stone, (consider the amount of air spaces!) 1 inch = or 1ft = ; 1 .

Blasting is the process where small angular or spherical particles are propelled at a part by compressed air, or mechanical high speed rotating wheels or water pumps . The blast media type, shape, size, density, and hardness, along with media acceleration and volume of media, combined with blasting distance from the workpiece, angle of

The selection of the correct stone infill is key to the performance of the system. If the correct stone is not used then the system will fail. The specification should be a 4/20 or 20/40mm stone clean angular stone in accordance with BS EN 1235. The clean stone infill allows water to .
Densities of various materials. Density of water at 0°C Density of water at 4°C Density of water at 100°C Density of ice Density of diamond Density of iron Density of copper Density of silver Density of gold Density of platinum
H The velocity and angular velocity at the bottom of the ramp can be calculated using energy conservation. The kinetic energy can be written as a sum of translational and rotational kinetic energy: K tot = K tran cm + K rot rel to cm = 1 2 mv cm 2 + 1 2 Icm w 2 where w is the angular speed of the rotation relative to the center of mass and Icm is the
Pit run gravel follows at tons per cubic meter, regardless of whether it is 2inch or 4inch. The heaviest of the crushed rock selections are Angular Rip Rap .
*Density Estimator Instructions: If you do not know the actual density, select the type of geology and product from the lists below and hit the "Estimate Density" button. An estimated density factor should then appear in the above density field.
