<p>: A method of forming a traffic-regulating indicium on a pavement, comprising forming a primer layer on the pavement by applying thereto a heated composition in flowable state which is of such a nature that the viscosity thereof increases as the temperature decreases from the temperature of application of said composition to said pavement, the composition having such a viscosity upon application thereof to the pavement that the composition intimately contacts the pavement, and said composition being capable of rapidly attaining a viscosity in the range of about 103 to 104 cP when said composition has a viscosity below this range upon being applied to the pavement , this composition further being capable of undergoing an increase in viscosity on the pavement from the range to a higher viscosity of at least 105 cP within a period of about 30 seconds, and applying a marker tape to the primer layer when the viscosity thereof is substantially in the range to thereby preliminary bond the marker tape to the primer layer, the marker tape becoming more securely bonded to the primer layer as the viscosity of the primer layer increases from the range towards the higher viscosity. And, an arrangement for producing an indicium on a pavement.</p> |
