Soil Stabilization Construction Procedures - 3 PDH
This is an introduction to the factors to consider in inspecting and repairing steel bridges.
This course will help you to address a variety of bridge inspection situations that may be encountered.
This course provides an introduction to construction procedures for stabilizing soils.
1. CONSTRUCTION WITH PORTLAND CEMENT
2. CONSTRUCTION WITH LIME
3. CONSTRUCTION WITH LIME-FLY ASH (LF) AND LIME-
CEMENT-FLY ASH (LCF)
4. CONSTRUCTION WITH BITUMEN
Upon completion of this course you will:
• Learn how In soil-cement construction the objective is to thoroughly mix a pulverized soil material and cement in correct proportions with sufficient moisture to permit maximum compaction;
• Learn how bulk cement is normally trucked to the jobsite in bulk transport trucks or shipped to the nearest railroad siding in enclosed hopper cars. Compressed air or vibrators are used to loosen the cement in the hopper cars during unloading. Transfer to cement trucks is done pneumatically or by a screen or belt conveyor;
• Learn how in a mechanical cement spread, mixed-inplace construction system, a mechanical cement spreader is attached to the dump truck, and as the truck moves forward, cement flows through the spreader, which regulates the quantity of cement placed on the prepared soil.
• Learn how to properly analyze and design repairs that involve adding metal to steel bridge members and elements:
• Learn how members to be strengthened must be investigated for any decrease in strength resulting from temporary removal of rivets, cover plates, or other parts; and
• How to repair loose or missing rivets.
This course is intended for civil engineers and bridge maintenance managers interested in learning about bridge inspection and repair techniques.
Benefit for Attendee
This course will give civil engineers and bridge managers advice and recommendations on bridge repair techniques.
