Claim 1

A method of providing a traffic surface with both anti-slip and retro-reflective characteristics, comprising a first step of applying to the surface a first coating of paint, a second step performed before the first coating has set, of distributing solid particles on the first coating to sink partially into the first coating, a third step, performed subsequent to said second step, of applying a second coating of paint, said second coating of paint being applied over the particles and the first coating to lock the particles into the first coating with the particles projecting from the second coating, and a fourth step performed before the second coating is set, of distributing retro-reflective beads over the second coating to sink partially into the second coating between the projecting particles for bonding the beads into the second coating with the beads projecting from the second coating, the beads being smaller than said particles and the particles projecting from the second coating by more than the beads to overshadow the beads.

Claim 2

A method of providing a traffic surface with both anti-slip and retro-reflective characteristics, comprising a first step of applying to the surface a first coating of paint, a second step performed before the first coating has set, of distributing solid particles on the first coating to sink partially into the first coating, a third step, performed subsequent to said second step, of applying a second coating of paint, said second coating of paint being applied over the particles and the first coating to lock the particles into the first coating with the particles projecting from the second coating, and a fourth step performed before the second coating is set, of distributing retro-reflective beads over the second coating to sink partially into the second coating between the projecting particles for bonding the beads into the second coating with the beads projecting from the second coating, the beads being smaller than said particles and the particles projecting from the second coating by more than the beads to overshadow the beads.

Claim 5

A method of laying down a friction surface on a part of a traffic substrate of an aircraft-movement area, comprising the steps of priming said part of the substrate, applying a first coating of paint to a controlled thickness to the primed-part of the substrate, the priming step rendering said part of the substrate non-porous to the paint, distributing friction particles evenly on the first coating before the first coating has set, the friction particles being of a particle size to sink only partially into the first coating, applying a second coating of paint of controlled thickness to the first coating to lock the particles into the first coating with the particles projecting from the second coating, the thicknesses of the first and second coatings being controlled in relation to the particle size of the particles to leave substantially one third of each particle projecting from the second coating, the method including a further step performed before the second coating is set, of distributing retro-reflective beads over a defined region of the second coating to sink partially into the second coating between the projecting particles for bonding the beads into the second coating with the beads projecting from the second coating within said region, the beads being smaller than said particles and the particles projecting from the second coating by more than the beads to overshadow the beads within said region.

Claim 6

A method of laying down a friction surface on a part of a traffic substrate of an aircraft-movement area, comprising the steps of priming said part of the substrate, applying a first coating of paint to a controlled thickness to the primed-part of the substrate, the priming step rendering said part of the substrate non-porous to the paint, distributing friction particles evenly on the first coating before the first coating has set, the friction particles being of a particle size to sink only partially into the first coating, applying a second coating of paint of controlled thickness to the first coating to lock the particles into the first coating with the particles projecting from the second coating, the thicknesses of the first and second coatings being controlled in relation to the particle size of the particles to leave substantially one third of each particle projecting from the second coating, the method including a further step performed before the second coating is set, of distributing retro-reflective beads over a defined region of the second coating to sink partially into the second coating between the projecting particles for bonding the beads into the second coating with the beads projecting from the second coating within said region, the beads being smaller than said particles and the particles projecting from the second coating by more than the beads to overshadow the beads within said region.

Claim 7

A method of laying down a friction surface on a part of a traffic substrate of an aircraft-movement area, comprising the steps of priming said part of the substrate, applying a first coating of paint to a controlled thickness to the primed-part of the substrate, the priming step rendering said part of the substrate non-porous to the paint, distributing friction particles evenly on the first coating before the first coating has set, the friction particles being of a particle size to sink only partially into the first coating, applying a second coating of paint of controlled thickness to the first coating to lock the particles into the first coating with the particles projecting from the second coating, the thicknesses of the first and second coatings being controlled in relation to the particle size of the particles to leave substantially one third of each particle projecting from the second coating, wherein the distribution of the particles on the first coating is limited to only part of the first coating to delineate a region of the superimposed first and second coatings that is free of the distributed particles, and wherein the method includes a step performed before the second coating is set, of distributing retro-reflective beads within said region to sink partially into the second coating for bonding the beads thereto with the beads projecting from the second coating within said region, the beads being smaller than said particles and the particles projecting from the second coating by more than the beads to overshadow the beads within said region.

Claim 8

A method of laying down a friction surface on a part of a traffic substrate of an aircraft-movement area, comprising the steps of priming said part of the substrate, applying a first coating of paint to a controlled thickness to the primed-part of the substrate, the priming step rendering said part of the substrate non-porous to the paint, distributing friction particles evenly on the first coating before the first coating has set, the friction particles being of a particle size to sink only partially into the first coating, applying a second coating of paint of controlled thickness to the first coating to lock the particles into the first coating with the particles projecting from the second coating, the thicknesses of the first and second coatings being controlled in relation to the particle size of the particles to leave substantially one third of each particle projecting from the second coating, wherein the distribution of the particles on the first coating is limited to only part of the first coating to delineate a region of the superimposed first and second coatings that is free of the distributed particles, and wherein the method includes a step performed before the second coating is set, of distributing retro-reflective beads within said region to sink partially into the second coating for bonding the beads thereto with the beads projecting from the second coating within said region, the beads being smaller than said particles and the particles projecting from the second coating by more than the beads to overshadow the beads within said region.
