Abstract
Abstract A method of joining and sealing asphalt planks in butting relationship, using a preformed bituminous strip having substantially permanent non-hardening, pliable, yieldable characteristics for enabling the planks to shift due to shrinkage of the planks themselves, shifting of the ground or other base thereunder, or shifting or change in dimensions for any other reasons.

A METHOD OF JOINING ASPHALTIC PLANKS TO FORM A SUBSTANTIALLY PERMANENTLY WATERTIGHT RESEVOIR OR THE LIKE, COMPRISING THE TEPS OF: POSITIONING A PLURALITY OF ASPHALITIC PLANKS OF RELATIVELY STIFF MATERIAL ON A BASE, WITH THE EDGES OF THE PLANK IN SUBSTANTIALLY BUTTING NON-OVERLAPPING RELATIONSHIP TO THEREBY FORM A PLURALITY OF LONGITUDINAL AND LATERAL SPACES BETWEEN SAID EDGES; PLACING A PRIMER ON THE UPPER SURFACES OF THE PLANKS ADJACENT THE LONGITUDINAL AND LATERAL SPACES BETWEEN THE EDGES OF THE PLANKS, AND APPLYING SEALING STRIPS OF SUBSTANTIALLY PERMANENTLY NONHARDENING YEILDABLE SOLVENT-FREE BITIMUNOUS MATERIAL EACH OF SAID STRIPS HAVING A STRIP OF WOVEN FIBERGLSS ON ITS UPPER SURFACE, ON SAID PRIMED UPPER SURFACES AND EXTENDING ACROSS EACH OF SAID LONGITUDINAL AND LATERAL SPACES TO FORM A SEALED WATERTIGHT JOINT BETWEEN EACH OF THE ADJACENT PLANKS WHICH DOES NOT CRACK AND WHICH YEILDS TO ACCOMMODATE SHIFTING OR OTHER RELATIVE MOVEMENTS OF THE PLANKS WHILE MAINTAINING THE SEALED JOINT.

Claim 3
Dependent Claim
17 words
The method set forth in claim 1, wherein: said primer is an asphaltic base in a solvent.
Claim 4
Dependent Claim
29 words
The method set forth in claim 1, wherein each of the planks comprises: a central asphaltic core; and upper and lower reinforcing layers on each side of said core.
Claim 5
Dependent Claim
17 words
The method set forth in claim 1, wherein: said asphaltic planks are staggered relative to each other.
Claim 6
Dependent Claim
72 words
The method set forth in claim 1, wherein the composition of said sealing strips comprises: from about 45 percent to about 95 percent of petroleum derived bitumen residual having a Saybolt-Furol viscosity at 210* Fahrenheit of from abouT 50 seconds to about 250 seconds; and with essentially all of the remainder an additive selected from the group consisting of finely ground inorganic silicates, vegetable fibers, mineral fibers, rice hulls, and mixtures thereof.
Claim 7
Dependent Claim
50 words
The method set forth in claim 1, wherein: each of said asphaltic planks has its upper and lower surfaces protected by a releasable silicone coated sheet prior to installing same; and said sheets are removed at the site for installation of said planks to form the reservoir or the like.
