Abstract: A truck having a road oil spreader is equipped with an apparatus for simultaneous application of oil and paving fabric to the road surface. The apparatus includes an assembly for engaging a roll of paving fabric comprising adjustable cone arms mounted on a collapsible boom that rotatably hold the core section of the fabric roll. The fabric is drawn over an idler shaft and beneath a series of longitudinally aligned brushes. The shaft and brushes are connected to each opposing end of the oil spreader by a removable outwardly extending side framework. The framework includes joint and connection means that permit longitudinal and angular adjustment of the idler shaft and brushes. As oil is sprayed over the road surface, the fabric unrolls and becomes embedded in the oil by action of the brushes pushing the fabric into the oil-coated surface.

Abstract: A marking system indicates the location of lanes which are to be defined on a running track that has a given width and selected degree of curvature. A pivot is established at a fixed distance from the lanes to be marked. A boom assembly disposed laterally across the track carries a plurality of lane-marking devices individually spaced therealong. That assembly is supported for movement along the track. One end of the boom is propelled by a propulsion unit, and an alignment unit is coupled to the other end of the boom for enabling alignment movement relative to the pivot. A cable leads from the outer end of the boom over the inner end thereof and to the pivot for enabling alignment. Numerous detailed features contribute to an attainment of accuracy measured in fractions of an inch.

Abstract: This invention regards a method for assuring high retro-reflecting capability and long service life for horizontally-installed roadway-marking strips. The same method also provides for making marking strips that are already installed visible in rainy weather. This invention also concerns the relative equipment for applying the method.

Abstract: A pavement line striper is provided which has a pair of spaced apart front wheels and a pivotable rear steering wheel. Paint spray guns may be mounted closely adjacent to one or both of the front wheels. One of the front wheels is laterally movable to allow for the painting of parallel stripes of selectively variable spacing. Two guns may be mounted on one side for vertical and horizontal spraying of a curb in one pass or for closely spaced parallel lines. The guns remain closely adjacent the wheels to minimize uneven thickness of the lines when spraying on uneven terrain. The rear wheel is lockable against pivoting movement and indicia markings are provided to permit selection of a radius for curved lines.

Abstract: A preheater for melting a slab of thermoplastic marking material preparatory to applying a melt therefrom onto a paved surface has a heated slab receiver formed with a side wall oriented between 70.degree. and 82.degree. with respect to a reference ground plane upon which surface a slab may be flushly supported for heating and melt down.

Abstract: In the illustrated applicators, one of a series of pavement markers is individually dispensed from a carrier web by stripping the web back from the marker while moving the marker into wedging contact between a spring-loaded roller and the pavement. While doing so, the carrier web is kept taut between a brake shoe where it exits a magazine and an overdriven takeup roll which is locked against rotation while the marker is being moved into the wedging contact. Each pavement marker has a flat base which preferably bears a pressure-sensitive adhesive that releasably adheres the marker to the carrier web and bonds the marker to the pavement.

Abstract: This invention concerns treatment of the heat-fusible materials by use of a fusing agent, according to which a fusing agent capable of producing red hot "embers" by combustion is applied to the surface of a worked object such as a sign formed from a heat-fusible material and worked at a construction site or to the area to be newly worked, and then said fusing agent is ignited and burned so that the combustion heat of the resultantly produced "embers" is directly conducted to the material to be worked to thereby remove the fused material from the worked area or fuse and affix the material to the working area.

Abstract: A raised marker is produced by inserting molten resin material, which has been premixed with a hardner or catalyst, into an open mold so that the resin conforms to the shape of the mold. The mold, prior to the time the resin cures or sets up, is inverted and placed on the pavement so that the resin, itself bonds to the pavement surface. The mold may be removed or remains as a permanent shell for the marker. A parting agent is used when the mold is to be removed. Color pigments and/or inserts in the form of glass beads or other reflective elements may be incorporated in the resin. Mechanism is shown for automatically filling and depositing the molds.
