Beyond the critical importance of protecting human health and preventing contagious disease, properly designed and produced manholes ensure the safety of workers who handle precast products, and in the long run guarantee quality precast products that comply with accepted industry practices and prevent unnecessary increases in cost to the consumer.

These standards play a pre-eminent role in all aspects important to the effective standardization of concrete asrm, including material specifications, test methods and installation practices. The owner of the project for which these products are specified herein is cautioned to require inspection at the construction site.

Experience has shown, asttm, that the successful performance of this product depends upon the proper selection of the product strength, type of foundation and backfill, and care in the field installation of the manhole products and connecting pipes. Aggregates shall conform to the specificationexcept that the requirements for gradation shall not apply.

Under the jurisdiction of Subcommittee C We have no amendments or corrections for this standard. Risers and Conical Tops. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials and water as will produce as homogeneous concrete mixture of such quality that the products will conform to the test and design requirements.

Aggregates shall conform to the specificationexcept that the requirements for gradation shall not apply. Work Item s – proposed revisions of this standard. To improve the testing of manhole section gaskets, the discussions in C led to c47 profile wall gasket, a connection with no notch that can be reset in the manhole.

Note 2—This specification is a manufacturing and purchase specification only and does not include requirements for backfill, or the relationship between field load conditions and the strength requirements of the c4778 products and appurtenances.

ASTM Manhole Specifications

This specification covers the manufacture and purchase requirements of products used for the assembly and construction of circular vertical precast reinforced concrete manholes and structures used in sewer and water works.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM C and joint materials C opened up new manufacturing standards for joint materials as gasket material technology evolved. The following specifications apply to manhole connectors and joints: The scope of C includes structures used in precast sewer, drainage and water works.

The emergence of the Clean Water Act established the basic structure for regulating astmm of pollutants into the waters of the United States and regulating quality standards for surface waters.

As the voice of the U. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials and water as will produce as homogeneous concrete mixture of such quality that the products will conform to the test and design requirements.
