Durable debris and alkaline resistant preformed thermoplastic runway pavement marking compositions
Disclosed are PP/PE copolymer backbone based pre-manufactured thermoplastic airport signage compositions primarily applied in relatively large sections onto airport runways, taxiways, and additional paved surfaces. The composition provides alkali resistant formulations comprising at least 6 weight percent PE/PP, 20 weight percent binder resin with between 5 and 15 weight percent of a tackifier resin, between 2 and 12 weight percent titanium dioxide with an optional organic dye, wherein the intermix is at least 30 weight percent of the composition and wherein the intermix is an inorganic filler that greatly reduce or eliminate debris resistance when compared to other polymer backbone compositions.

Expediently Installable Traffic Calming System
A traffic calming system is provided that can remain in place on the ground without additional attachment while a vehicle grazes or traverses it. The traffic calming system includes a variety of modular units that can be laid out in any desired pattern as needed to direct a flow of traffic. The modular units can be connected together in an arrangement such as for a roundabout or splitter island. The modular units can be arranged individually as lane markers, such as for a bicycle lane or pedestrian lane, or to outline a roundabout or splitter island.

Roadway surface compositions and pelletized binder materials thereof
A composition for applying onto a road surface and methods for making thereof is disclosed. The composition comprises a binder material of at least a styrenic block copolymer and a resin, which can be pelletized. The SBC is selected from a styrene-isoprene-styrene rubber (SIS) and styrene-isoprene/butadiene-styrene (SIBS); or styrene-ethylene/propylene/styrene-styrene (SEPSS), styrene-ethylene/butylene/styrene-styrene (SEBSS) and mixtures thereof. The binder can be used in road marking compositions or surface treatment compositions when combined with other components such as pigments, glass beads, anti-skid media, fillers, waxes, elastomer/plastomer, and plasticizers.
Reconfigurable one piece water permeable paver
A reflective and directional water permeable paver system, which has a plurality of connection cells and is configured to support traffic, includes a marker insert. The marker insert has a continuous body wall with at least one tensioning marker rib extending from the continuous body wall. The marker insert has an insert head. The insert head diameter extending beyond the continuous body wall of the marker insert. The marker insert body diameter is substantially equal to the inner wall diameter of at least one of the connection cells.

LUMINESCENT RAISED PAVEMENT MARKER
A raised pavement marker (RPM) is sized and configured to comply with Department of Transportation requirements and includes a main body with a top side, opposite angled side faces, opposite ends and a bottom surface structured to be bonded to a road surface. A sheet substrate is coated on a top surface with multiple layers of a photoluminescent composition containing one or more rare earth materials that emits a highly visible glowing light in dark or near dark conditions for at least 6 hours when fully charged. The sheet substrate is inserted within a recessed pocket on the top side of the RPM with the photo-luminescent top surface facing up and is covered by a transparent acrylic lens that is electronically welded to the main body to provide an integral one piece sealed structure. The opposite angled side faces may be fitted with prismatic reflective lenses.
