PROVISIONAL SPECIFICATION.
Improvements in and connected with Asphalt, Concrete, and like
Structures and Constructions.
I, THOMAS WILLIAM HELLIWELL, of Brighouse, in the County of York, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new means and method of making, constructing and
laying asphalt or concrete used for covering railway arches, roofs, walls, floors,
cisterns, reservoirs, and other buildings or structures where suitable.
The asphalt or concrete used may consist of any kind of rock asphalt or bitumen,
Portland or other cement, tar, pitch, limestone, creosote or other suitable oil, irou
or steel borings all mixed together and made into a plastic substance, which is after-
wards spread in layers upon the structure intended to be covered, and between
each layer it is my intention to insert wire, or wire network of any suitable kind
so that on the several layers being compressed together, the, asphalt or concrete will
pass between the interstices of the wire or network and become thereby cemented so
as to form one solid homogeneous thickness notwithstanding the presence of network
between each layer.
or
The network above referred to may be composed of ordinary iron or steel wire
or of copper or any other suitable metal or material, and instead of using wire
network, I may use perforated sheets composed of metal, paper, or cardboard
narrow strips of metal or suitable lengths of wire may be used and arranged in any
convenient manner between the layers of asphalt to attain the same object. The
sheets of network or other suitable material to be inserted between the layers of
asphalt may be zigzag, corrugated or flat.
The composition, together with the intervening network, may be made in continuous
lengths or slabs, which can afterwards be made watertight by running asphalt
between the joinings of the slabs. ;
In making, constructing or laying of asphalt according to my invention the first
insertion of network may be zigzag or corrugated, the second insertion of network
may be flat, and the third, if used, may be again zigzag or corrugated, but the
méthod of arrangement in regard to the insertion of the network may vary according
to the class of work under operation and to the judgement of the manufacturer.

Improvements in and connected with Asphalt, Concrete, and like
Structures and Constructions.
I, THOMAS WILLIAM HELLIWELL, of Brighouse, in the County of York, Civil
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to a new means and method of making, constructing, and
laying asphalt, concrete, or other suitable material used for covering railway arches,
roofs, walls, floors, cisterns, reservoirs, and other buildings, structures, roads, or
grounds, where suitable. The asphalt or concrete used may consist of any kind of
rock asphalt or bitumen, Portland or other cement, tar, pitch, limestone, creosote or
other suitable oil, iron or steel borings, or any combination of said substances mixed
together and made into a plastic substance, which is spread in layers upon the

page_text: structure intended to be covered, and between each layer it is my intention to insert
wire, or wire network, of any suitable kind and design, and to compress together the
several layers of asphalt or concrete and wire network.
The network above referred to may be composed of ordinary iron or steel wire,
or of copper or any other suitable metal or material. Instead of using wire network,
I may use perforated sheets composed of metal, paper, or cardboard; or narrow
strips of metal, or suitable lengths of wire may be used, and arranged in any con-
venient manner between the layers of asphalt to attain the same object. The sheets
of network or other suitable material to be inserted between the layers of asphalt may
be zigzag, corrugated, or flat.
The composition, together with the intervening network, may be made in continuous
lengths or slabs, which are afterwards laid as required, the joinings thereof being made
watertight in any suitable manner.
In making, constructing, or laying of asphalt according to my invention, the first
insertion of network may be zigzag or corrugated, the second insertion of network
may be flat, and the third, if used, may be again zigzag or corrugated, but the method
of arrangement, in regard to the insertion of the network, may vary according to class
of work under operation, and to the judgment of the manufacturer.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The making, constructing, or laying of asphalt or concrete and other like substances
in layers or divisions, in combination with intervening network in manner substan-
tially as herein described.
