MODIFICATION AND ASSESSMENT

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.

The present disclosure involves processes for assessing and modifying pavement surfaces using a mobile platform. An emitter associated with the mobile platform generates electromagnetic waves directed towards a portion of a pavement surface. A condition sensor associated with the mobile platform 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.
