Hi everyone, I m from Hong Kong. this is my first post in this forum and i would like to ask about the advantages of herringbone bonded brick pavers, compared to i) stretcher & ii) basketweave bond pattern. i would appreciate if you could answer the following questions:

1) is it true that herringbone bonded brick pattern can take heavier imposed loadings compared to i) and ii)? is it particularly more suitable for areas with vehicular traffic?
(if yes, can you explain more, such as regarding the loadbearing behavior?)

2) is it true that herringbone bonded brick pattern can spread the imposed loadings more evenly, compared to i) and ii)? if yes, why?

3) besides BS 7533, is there any papers explaining the technical advantages of using herringbone bond brick patterns for pavement construction over other patterns?


thanks very much for your help. and pls pardon my english because i m not a native speaker.

regards,


Jomos

These questions are more than answered on the main website.

You're right that herringbone is better for loads but the only explanation I can give is that compared to other patterns with herringbone each block interlocks better with its neighbour, sorry I'm not engineering proficient to explain it better.

Taken from the section 'Paving Layer' on this page
http://www.pavingexpert.com/blocks2.htm
A fully interlocked 'Herringbone' pattern should be used for areas to be trafficked by vehicles whenever possible or practical. Other patterns are fine for foot-traffic areas such as paths and patios.

search through the previous posts in the brew cabin i am sure the basket weave subject has come up before the gaffer (site manger/owner) has explained in perfect detail the reasons/advantages/problems with various different paving layouts

sounds like this is for a commercial or government project and your an architect or specifier / engineer.

i would say if you want a definitive answer then contact tony and pay the man, this is his bread and butter. if your a student etc then this might help.

so doing a bit of research because i'm bored and things like this interest me and i'll be dammed before i watch celeb big brother

interesting read incorrect details in there about bedding sand used to joint the pavers but interesting read about petroleum penetration compared to concrete

more to follow reading....

interesting read about installation of a high street in canada,out of date but i enjoyed reading it.

quote: A herringbone pattern in the streets
offered the greatest degree of interlock for
the pavers (Figure 8).

third paper i have read that states this but no one goes into detail or quotes a source for it, very bad paper writing no siting of evidence etc.

south african study: cost comparison of interlocking modular paving and remix asphalt

another interesting read this one more general block paving well worth a read gents.

the main strength in herringbone is the lack of straight joints i.e. no straight joint longer than 300mm
this offers the greatest degree of interlock

there is no search results for "basket weave" apart from this thread.... :(

jomos have a look here about 3/4 of the way down
if you need to specify for car parks or high trafic areas you want these W or S shaped blocks they give the highest degree of interlock
the more interlock the less chance of creeping or rutting which we have all seen too often with stretcher bond or basket weave
all the best
