SOIL COMPACTION
Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio.
•The principal reason for compacting soil is to reduce subsequent settlement under working loads
• Compaction increases the shear strength of the soil.
• Compaction reduces the voids ratio making it more difficult for water to flow through soil. This is important if the soil is being used to retain water such as would be required for an earth dam.
• Compaction can prevent the build up of large water pressures that cause soil to liquefy during earthquakes.

This code covers welding fabrication requirements applicable to welded highway bridges. It is to be used in conjunction with the AASHTO Standard Specification for Highway Bridges or the AASHTO LRFD Bridge Design Specifications.
This code covers the welding requirements for AASHTO welded highway bridges made from carbon and low-alloy constructional steels. This 2002 edition contains dimensions in metric SI Units and U.S. Customary Units. Sections 1 through 7 constitute a body of rules for the regulation of welding in steel construction. Section 9 of the previous edition has had its provisions distributed throughout the 2002 edition. Sections 8, 10, and 11 do not contain provisions, as their analogue D1.1 sections are not applicable to the D1.5 Code. Section 12 contains the requirements for fabricating fracture critical members.
