Estimating Percent Sand in a Soil
มุมมอง 855 ปีที่แล้ว
The Soil Syringe Method was developed by Amster Howard as a way to determine the percent of sands and the percent of fines in a soil.
Diggability of Flowable Fill
มุมมอง 5K8 ปีที่แล้ว
The excavation of 30 day old flowable fill is shown. Flowable fill should have a compressive strength between 20 and 80 psi (150 to 600 kPa) so that it can be easily excavated for repairs, future installations, etc.
Mounding (Why Not To)
มุมมอง 958 ปีที่แล้ว
The ill-advised method of mounding used to install pipe is shown. The pipe is supported on each end on a mound of soil. This is done to place the pipe at a certain elevation. Since it is practically impossible to compact beneath the pipe, a loose zone between the mounds results. The mounds may end up as hard spots creating point loading on the pipe.

Spread Test for Flowable Fill
มุมมอง 6K8 ปีที่แล้ว
Illustrates the procedure in ASTM D 6103 " Flow Consistency of CLSM." A 3-inch by 6-inch cylinder is filled with flowable fill and raised. The mixture consistency should result in an 8- inch to 12- inch diameter patty.

Creating Lack of Support in Pipe Haunch
มุมมอง 6410 ปีที่แล้ว
Demonstrates how the angle of repose of crushed rock creates a void in a pipe haunch when the rock is dumped in beside the pipe. Without shovel slicing or compaction, the void means there is not support for the pipe in the haunch area. Note that when the slope of the crushed rock contacts the pipe, no more rock is able to move under the pipe
