June 6,1944 Operation Overlord, the Normandy invasion - like William the Conqueror's before it or the Inchon landing afterwards - will long be studied as a classic in military planning, logistics, and operations. Overlord depended to a remarkable degree upon the use of air power in virtually all its forms. A half-century ago, aircraft were primitive vehicles of war compared to the modern attackers of the Gulf War era, with their precision weapons, advanced navigational, sensor systems, and communications. Yet, the airplane still had a profound impact upon the success of the invasion. Simply...

This manual establishes criteria for improving the engineering properties of soils used for pavement base courses, subbase courses, and subgrades by the use of additives which are mixed into the soil to effect the desired improvement. These criteria are also applicable to roads and airfields having a stabilized surface layer. This manual prescribes the appropriate type or types of additive to be used with different soil types, procedures for determining a design treatment level for each type of additive, and recommended construction practices for incorporating the additive into the soil.

This manual provides criteria and guidance for the design of structures to resist the effects of earthquakes. It takes a general approach for the seismic design of buildings, including architectural components, mechanical and electrical equipment supports, some structures other than buildings, and utility systems. Primary emphasis is given to the equivalent static force design procedure.

This manual was prepared to provide guidance in the use of pressure grouting as a means to correct existing or anticipated subsurface problems. Information on procedures, materials, and equipment for use in planning and executing a grouting project is included, and types of problems that might be solved by pressure grouting are discussed. Methods of pressure grouting that have proven to be effective are described, and various types of grouts and their properties are listed.
