The present disclosure relates to a road marking paint composition for painting a coating a road substrate adapted for accelerated cure by exposure to UV light.

A road marker system for dispensing a plurality of markings at a uniform distance on a road. wherein the road marker system comprises a frame. wherein, the frame is configured to attach a spraying assembly to a vehicle and position the spraying assembly at a visible distance from a vehicle driver. A chain assembly comprises a plurality of sprocket wheels with a chain wrapped circulating around the plurality of sprocket wheels. A circulating striker assembly is attached to an exterior portion of the chain. wherein, the circulating striker assembly is configured to circulate around the chain as the chain circulates around the plurality of sprocket wheels. The road marker system further comprises a valve nozzle release having a paint bottle.

A mobile platform for assessing and modifying pavement surfaces. An emitter generates electromagnetic waves towards a portion of a pavement surface. A condition sensor receives electromagnetic radiation from a first portion of the pavement surface and generates a first electronic signal representative of a current condition of the portion of the pavement surface. A location sensor generates a second electronic signal containing location data corresponding to the first portion of the pavement surface. A computing platform processes the electronic signals and creates a current pavement condition data point. The computing platform may compare the first electronic signal against a reference representative of a target condition, determine if there is a condition variance, and, if a condition variance exceeds a predetermined threshold, generate a condition control signal which is transmitted to and operates to modify operation of the pavement surface modification system in order to reduce the condition variance.

An automatic and intelligent spraying device for traffic marking intelligent. The spraying device for traffic marking includes a fixed bottom plate, a coating storage tank, a control box provided with a controller, an armrest, a row of nozzles, a speed sensor, and a driving motor. The coating storage tank is connected with coating pipes equipped with an electromagnetic valve. The fixed bottom plate is provided with a driving motor and rotating wheels. The driving motor drives the rotating wheels to move. The speed sensor is electrically connected with the controller and the driving motor. The controller controls a speed of the driving motor according to speed information detected by the speed sensor. The controller controls the driving motor, and controls the row of nozzles to spray according to a preset spray marking and spray pattern through the electromagnetic valve.

This application provides an intelligent two-dimensional traffic marking spraying device, to reduce the construction amount of workers, improve the construction quality and the work efficiency. The intelligent two-dimensional traffic marking spraying device includes a baseplate, a coating storage tank, a control box, a armrest, a row of nozzles, a speed sensor, a drive motor and four rotary shafts. When spraying traffic marking, the builders first select the marking, then set the next base point, and turn on the main switch. The coating contained in the coating storage box enters into the nozzle and sprays out. Meanwhile, the solenoid valve opens and closes at the corresponding position through the feedback information of the speed sensor and the control of the controller, so as to achieve the purpose of spraying two-dimensional traffic marking.

Trafficked pavement substrates utilize markings to segregate traffic (e.g., divide lanes traveling in the same direction, divide sides of the road traveling in opposite directions). A dry polymer modified cement mixture may be used to provide the markings. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water. The location of the lines is identified, and the dry polymer modified cement mixture is applied onto the identified areas as a thin layer. The dry polymer modified cement blend may include polymers to provide colored markings. Glass beads may be embedded into the dry polymer modified mixture before it cures to retroreflect light shined thereon. The trafficked pavement substrate may have troughs formed therein and the dry polymer modified cement markings may be formed therewithin so that the markings are flush.
