Abstract:Specifications apply to construction of portland cement concrete pavements and bases under normal conditions for both highways and airports. Standards and specifications of several other organizations arc incorporated by reference. Sources and acceptance standards for materials are given, as well as ma-terials testing procedures and procedures for test of concrete strength to be used as a basis for proportioning of mixtures. Specifications for the materials a nd construction of soil foundations for concrete pavements and concrete bases are included. Provision is made for use of foundations stabilized by a cementing agent, but materials and construction of such arc beyond scope of this specification. Materials, dimensions, setting, and removal of forms are treatrd. Construction methods are specified for forming joints, installation of joint seal and load transfer devices, and placing of reinforcement. Concrete propor-tioning based on design for minimum strength is covered in detail; proportioning based on fixed cement content is allowed. Other sections cover production of high-early-strength concrete and the handling and mixing of materials. Detailed requirements are given for placing, finishing, and curing of pavement concrete. Check of thickness of finished pavement is cited as basis for adjustments in payment to contractor. Protection of finished pavement, opening it to traffic, and public use of thoroughfare during construction are also specified.
