A roadway subsurface sensor system includes roadway housings arranged to define a surface to carry vehicles. Each roadway housing has a sensor assembly having a housing, and sensor layers received by the housing. Each roadway housing also has a drainage layer under the sensor assembly. An uppermost sensor layer from the sensor layers is to provide the surface to carry vehicles. The roadway subsurface sensor system further includes a management controller coupled to the sensor layers. The management controller is configured to process sensed data from the sensor layers.

A method or applying a fast curing epoxy traffic marking composition is provided in which curing agents are coated on a carrier such as glass beads or porous silica. These carriers are dropped onto the epoxy coating and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface.

A method of airfield markings assessment and scheduling predictive maintenance periodically measures characteristics of individual portions of an airport's runways, and identifies the measured locations. The periodic individual portion measurements the airfield's runways and such measurements at similar airfields' runways are used to determine projections of how long the runway's individual marking portions will separately comply with FAA's marking requirements and the results used to schedule a predictive maintenance program which periodically removes and replaces less than all of the runway's markings.

In some embodiments, a directional surface marking may provide directional messaging to users based on their direction of travel on a base surface, such as a roadway, walkway, or interior flooring, as non-limiting examples. In some aspects, the directional messaging may comprise different colors, text, or symbols, wherein a user may view different directional messaging on a directional surface marking dependent on direction of travel. In some embodiments, directional surface markings may comprise a profile layer, wherein the profile layer may comprise a plurality of profiles, which may allow for an application of directional messaging.

A roundabout for vehicular traffic is provided from a plurality of modular blocks arranged in a generally circular roundabout pattern and affixed to a roadway or ground surface at an intersection of vehicle roadways. Roundabouts can be formed in any desired diameter. In some embodiments, the modular blocks can have a trapezoidal plan shape laid out in concentric rings. The trapezoidal shaped blocks can be cut from a length of board having a constant width and thickness. The modular blocks can be provided as a kit of parts delivered to worksite at an intersection of vehicle road-ways where a roundabout is desired. Splitter islands, sidewalks, and curbing of blocks having appropriate shapes can also be provided.

These carriers are dropped onto the epoxy coating and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface. This enables the application contractor to open a marked roadway in a quicker manner with less motorist disruption.
