Abstract
A detectable warning system comprising a mat substrate comprising a first acrylic material and a texture layer comprising a plurality of texture elements formed from a second acrylic material disposed on a top surface of the mat substrate. The mat substrate comprises a plurality of raised portions. The first acrylic material comprises an acrylic cement and an acrylic admix. The second acrylic material comprises the acrylic cement and the acrylic admix. The second acrylic material defines a plurality of texture elements on the mat substrate.
Claims25
A detectable warning system comprising:
- a mat substrate comprising:
- a first layer comprising cement, an acrylic material, and aluminum oxide;
- and
- a second layer comprising cement and an acrylic material but not aluminum oxide;
- wherein:
- the cement used in the first layer is the same as the cement used in the second layer;
- and
- the acrylic material used in the first layer is the same as the acrylic material used in the second layer;
- and
- a texture layer disposed on a top surface of the mat substrate, the texture layer comprising a plurality of texture elements formed from a second acrylic material;
- and
- wherein:
- the mat substrate comprises a plurality of raised portions;
- the second acrylic material comprises cement and acrylic material, wherein:
- the cement used in the second acrylic material is the same as the cement used in the first layer and the second layer;
- and
- the acrylic material used in the second acrylic material is the same as the acrylic material used in the first layer and the second layer;
- the plurality of texture elements comprise texture elements that are of a variety of different sizes and shapes positioned about the top surface of the mat substrate.
A method for making a detectable warning system comprising:
- providing a mat substrate comprising a plurality of raised features uniformly positioned about a top surface of the mat substrate on a support surface of a fabrication facility;
- preparing a texture element mixture;
- and
- forming a texture layer by applying the texture element mixture as a plurality of texture elements to the top surface of the mat substrate;
- wherein:
- the mat substrate comprises a cement and an acrylic material;
- and
- the texture element mixture comprises a cement and an acrylic material.
A mat substrate comprising:
- a top surface comprising a plurality of raised portions;
- a first acrylic layer comprising a cement, an acrylic material, and an oxide material;
- and
- a second acrylic layer comprising the cement, an acrylic adhesive, and the acrylic material;
- wherein the first acrylic layer defines the top surface and the second acrylic layer is configured to be positioned below the first acrylic layer when the mat substrate is in an operable position;
- and
- the first acrylic layer is harder than the second acrylic layer.
A mat substrate comprising:
- a top surface comprising a plurality of raised portions;
- a first acrylic layer comprising a cement, an acrylic material, and aluminum oxide;
- and
- a second acrylic layer comprising the cement, an acrylic adhesive, and the acrylic material, but not aluminum oxide;
- wherein the first acrylic layer defines the top surface and the second acrylic layer is configured to be positioned below the first acrylic layer when the mat substrate is in an operable position.
