I-J-K

I.S.A.
International Symbol of Accessibility. The correct term for what is often referred to as a “handicap symbol.” This familiar wheelchair design is used worldwide to denote areas designed to facilitate access for those with disabilities. (See also A.D.A.)

Infra-Red
Asphalt surface repair process which uses radiated heat to soften existing pavement. Most commonly the pavement is then raked and additional hot mix added. When raking is completed the area is re-compacted. This allows fast repairs with less new material and facilitates repairs in weather to cool for conventional methods. Not appropriate for areas of base failure or requiring structural repair. May also be used to soften pavement for texturing or decorative processes such as Street Print®.

Joints
An asphalt joint is the area where two different “pulls” of asphalt meet. This area is usually highly visible after the paving operation and is sometimes referred to as a “seam.”
