A computing platform is used to process the electronic signals and create a current pavement condition data point. The computing platform may compare the first electronic signal against a reference representative of a target condition of the portion of the pavement surface, determine if there is a condition variance, and determine whether any condition variance exceeds a predetermined threshold. If a condition variance exceeds a predetermined threshold, the computing platform may generate a condition control signal which is transmitted to a pavement surface modification system, and which operates to modify operation of the pavement surface modification system in order to reduce the condition variance.
