A inflexible pavement is taken into account to be any pavement method that includes as one aspect portland cement concrete, both non-reinforced or bolstered. This 1984 guide offers information for the layout of military airfield inflexible pavement at U.S. military mobilization installations. This handbook is proscribed to military airfield pavement layout standards for airplane in the course of a mobilization scenario.

The width of JRC pavement will generally be controlled by the concrete paving equipment and will normally be 25 feet, unless smaller widths are necessary to meet dimensional requirements. c. Limitations to JRC pavement design procedure. The design procedure for JRC pavements presented herein has been developed from a limited amqunt of investigational and performance data. 05. 5 percent steel reinforcement in figure 3-1 regardless of the percent steel used. (3) The maximum width or length of JRC pavement slab will not exceed 100 feet regardless of the percent steel used or slab thickness.
The cement 4-1 EM 1110-3-142 9 Apr 84 content may be all portland cement or a combination of portland cement and up to 25 percent fly ash or other pozzolans. e. Maximum size coarse aggregates should fall between 3/8 and 3/4 inch. The percent of coarse aggregate (of the total aggregate content) can vary between 25 and 60 percent. 4-4. Thickness determination. The required thickness of JFC pavement will be a function of the design concrete flexural strength R, the modulus of soil reaction k, the thickness hb and flexural modulus of elasticity Efs of stabilized material if used, the aircraft gross load, the volume of traffic, the type of traffic area, and the allowable vertical deflection.
