nate felt strips and build them intolayers,-
, or reinforce asphalt mixtureswith saturated 4 structure, so
i'elt sides, also, the prior art teaches fibrous matter mixed with tar, pitch or bituminous substances.
In all the above the mixture's'have been .eliected with heated liquid or semi-liquid materials, so that the contents are saturated thoroughly and the mass becomes a saturated" mixture and consequently contains ,few" if any air cells. On the other hand the rigidity of the fibre for structural purposes is destroyed, and it does not act as a separate structural skeleton for the surrounding mass. Consequently, in warm weather expansion joints made by the old method become limpand flabby, because of their lack of structural r in penetration power, I am able to effect astructural skeleton within the matrix which supports the matrix in warmer temperatures.
I am also able to efiect cells or areas in the structure-which allow for compressibility, and because of the unsaturated materials or cellular granules the walls of the bituminous matrix surrounding the granules cannot adhere tog ether upon compress on and will, therefore, respond toexpansien upon release of the compression. Certain fibres, such as, mineral wool, cause the walls of the matrix toharden immediately where in contact, which also makes for a. stronger that there is a structural strengthening both by chemical action and by preserved rigidity 1n the fibrous matter which is unsaturated. I have efl'ected through this method the possibility of eif ectingseveral t esof strue-. ture, namely, a bituminous an fibrous mlx- -nous matrix.
which is alread 'known to the art in 11 serial no. 559,908. Divided and um application filed motel-'19, 1925. Serial No. sass-z.
ture efiecting a chemical change, stren then-- ing the structure, ,a bituminous and brous mixture strengthening the structure due to unsaturated. fibrous matter; a bituminous, cellular structure containing within the cells granules, such as, .cork, which in itself is cellular, screened: mineral wool'granules,
which are also cellular, treated wool granules ofcellular or fibrous matted matter, such as, excelsior, digested straw, flax, .etc.-, in an unsaturated state, or-at least not solidly saturated, due to penetration of the bitumi- This casepertai-ns to bituminous material 1n awarm, plastic state, having incorporated therein cellulargranules for the purpose of providing cells throughout the mixture. The granules are unsaturated with the bituminous material so that they may be free of any adhesive materialwhich would allow the separated areas of bituminous material r in a cellular state, and any other like form to adhere whencompressed, thereb filling ,thecells and destroying the expansi ility of the granules.
This cellular material reacts upon itself, inother words, one-granule reacts against another granule, having intermediate the difi'erent granules, walls of bituminous material. The usual mixer employed for this purpose may be used, and the warm bituminous material placed therein, and while in this statethe cellular material or granules,
as described, are incorporated in proportions depending upon theresilieney of the product required.
A series or group of products, which,
when under pressure will react upon each other and compress, but upon releaseof the compression the granules will resume their former shape, by reason of the fact that there can be no adhesion between the walls of the bituminous ,material, because of theinterference of the cells filled with unpenetrated cellular matter.- 4
The usual method of forming the material intosheets and in expansion joint sizes may be employed, as previously known to the art, it being the purpose of this invention to protect merely the prepared materlals 111 the manner outlined, and not to claim any of the machinery which, might be utilized, and
and reducing t The drawing illustrates an expansion joint consisting of bituminous material, (a) having incorporated therein relatively large sized granules (c) for the purpose of providing cells or areas (03) throughout the ma terial, which are at all timesfree of any adhesive. The walls of bituminous material surrounding the granules. are thus separated andprevented from adhering when the material is compressed, thereby leaving the granules freely compressible and expansible.
An expansion joint as outlined above willhave the following properties:
It will resist heat penetration. It will contain a skeleton structure to give it strength before installation in the crevice.
It will be subject to considerable compression and will re-expand' with much less elements distributed through the mass, said elements being unsaturated withthe ductilematerial andarra'nged in close relation to allow adjacent elements to act resiliently against each other,

ductile bituminous material andcork grin-1 ules distributed throughout said mass, said cork'graiiules being freely compressible and expansible within the bituminous material.
