I am talking about case in middle east. 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. Dick Engineer and international traveler interested in construction techniques, problems and proper design.
In my opinion, the standard is very minimal and the demands of the specifiers and contractors over-ride the of the ASTM standard. What is common practice in US? Students Click Here Join Us! The use of pavers made using a wet cast method is not common because the wet cast units are probably not cost effective.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This abstract is a brief summary of the referenced standard. Are you an Engineering professional?
Thank you Mr Dick. To my knowledge, the the units you have visualized are not the typical “interlocking concrete pavers” that the specification written for, which is for heavy loads wheel loads than can be carried if installed properly.
Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. I am working in Kuwait. Download Now White Paper: 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. There are also very few if any manufacturers that meet the standards for the installation requirements. Link to Active This link will always route to the current Active version of the standard.
Kindly share your experience and knowledge. Promoting, selling, recruiting, coursework and thesis posting is forbidden. There are some features incorporated in the design of the paving units are not even addressed in C In your case, the ASTM contains a requirement that the the length to thickness of the unit be less than 4. The compressive strength is far below the level of the usual manufacturing equipment.
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 were used.
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. Which abrasion resistance test is more recommended for concrete unit pavers? Close this window and log in. The Eng-Tips staff will check asfm out and take appropriate action.

Thanks for your valuable comments. The specification also offers guidelines for physical requirements, sampling and testing, visual inspection, and rejection of specimens. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
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.

BS mention specifically about face mix concrete pavers. As you said,Tensile split strength has little effect if the pavers are of interlocking type.
