In your case, the ASTM contains a requirement that the the length to thickness of the unit be less than 4. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Standard Specification for Solid Concrete Interlocking Paving Units
Thanks for your valuable comments. Work Item s – proposed revisions of this standard.
Dear All, Kindly help me with your expertise knowledge in the below questions. What is common practice in US? I am sure they have had units tested in a lab somewhere that may have an acceptable machine to test such a long unit if the ASTM standards asfm used. I agree with you that the standard is very minimal, but when we deal the subject in construction contracts,though we specify the product with manufacturer name,the reference to International standards becomes mandatory.
Local sellers, however, should be consulted as to availability of units having the desired features. Join your peers on the Internet’s largest technical engineering professional community. I am talking about case in aastm east. If yes which standard is referred for this type of pavers? There are also very few if any manufacturers that meet the standards for the installation requirements. Click Here to join Eng-Tips and talk with other members!
Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. BS mention specifically about face mix concrete pavers. Dick Engineer and international traveler interested in construction techniques, problems and proper design.

This can effect the applicability of this factor based on the testing of the sample you referred to. Perhaps the supplier you mentioned can address the variation if they are active in writing the ASTM standard. I am working in Kuwait. The compressive strength is far below the level of asfm usual manufacturing equipment. ASTM Standard for Concrete Unit pavers sudhirvasan – If you refer to a standard ASTM cc936 others in your specifications, make sure you understand the specification and note the requirements that are excluded satm waived for your specific use.
Red Flag This Post Please let us know here why this post is inappropriate. The Eng-Tips staff will check this out and take appropriate action. There are some features incorporated in the design of the paving units are not even addressed asrm C This specification is intended for interlocking concrete pavers used in the construction of paved surfaces and awtm from cementitious materials, aggregates, chemical admixtures, and other constituents such as integral water repellents.
The psi compressive strength requirement is very low and a manufacturer could not afford to make the minimal units because this would require compromising other factors including handling and installation.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Thank you Mr Dick. How important is the split tensile strength test for concrete pavers? Defense manufacturing is all about project manufacturing and project accounting. Is there any ASTM standard which has mention about face mix type 2 layer semi dry cast concrete pavers?
The tensile splitting test is of no value since the pavers never see a similar loading because of the restraint and effects of the surrounding units. This paver is a long one, size mm x 72mm x mm,which has great potential for tensile splitting. In my opinion, the standard is very minimal and the demands of the specifiers and contractors over-ride the of the ASTM standard.
A typical concrete brick could be 12, psi. Engineer and international traveler interested in construction techniques, problems and proper design. The face layer does present some problems regarding determining durability testing, but does not preclude the use of a face layer, since it is a standard for type of construction material. To my knowledge, the the units you have visualized are not the typical “interlocking concrete aatm that the specification written for, which is for heavy loads wheel loads f936 can be carried if installed properly.
