![]() “ – – ” Parameter not determined, usually due to missing data.The "no data" icon is the result of an NWISWeb status code: The colored portion of the icon will represent the precipitation amount for that time interval. Half colored icons designate gage data that appears to be logging correctly but is over 1 hour and 15 minutes older than the NWISWeb time stamp at the top of the Rainfall page.Hourly and Daily values are calculated from the last time a gage value was updated, which is not necessarily the time this web page was updated. * For precipitation values less than 0.01 inches, the USGS gage symbol is white and the NWS overlay is transparent. The application speed depends on the type of application and goes up to 6 km/h.Legend colors apply to both USGS gage and National Weather Service precipitation overlays (at full opacity). This avoids settling and catching of solid parts and prevents unnecessary wear of mechanical parts. Continuous circulation of the thermoplastic material inside the equipment. It can be activated while extrusion is in process and is only slightly detectable on the line in the form of a moderate thickening of the layer. Pneumatically controlled quick cleaning system for removal of solids left in the extrusion slot. Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven. The shutters have no contact with the high tensile steel drum and therefore wear is minimalized and lifetime is prolonged. The number of dots/meter is 15-35 dots and is controlled by the LineMaster. The diameter of dots can be chosen between ø18 and ø 45 mm depending on the chosen drum. Consequently, the Dots will settle on top of the line with sharp edges, securing the optimum retroreflection. In other words, the material consumption will be predictable according to the adjustments and will not be as influenced by the type and condition of the road surface.īy using two sets of shutters the base line has time to cure slightly before the Dots are applied. Therefore, if the surface is rough or uneven, the line is the same as it follows the imperfections. The extruder also uses a different application method by extruding an even layer of material on the road surface. An alternative to the rib line equipment is the Borum thermoplastic extruder with which you can apply various flat and profiled markings. The rib line equipment is a good solution if you are only going to work with flat fixed-line width markings and rib line application. Generally, thermoplastic is recommended for areas with high traffic density and/or areas with low lighting as e.g. Thermoplastic markings cure quickly and adhere strongly to the road surface. Thermoplastic material has a long-life duration with high retro-reflectivity capabilities due to being able to pre-mix glass beads in the material. The base line is recommended to be as thin as possible when combined with ribs (approx. The total height of line with rib is usually between 8 to 15 mm depending on the material. This allows you to apply ribs over a line in one pass. RIB LINE FUNCTIONThe screed box is also equipped with a rib function. If you do not need to switch the line widths often, you have the option to only change the application opening based on your width requirements instead of changing the whole box! This makes the application equipment more cost-efficient!The thickness for the application of flat lines is usually between 2 - 4 mm.The usual application speed for applying ribs over a flat line is 1-3 km/h, while for screed application of flat lines it is up to 5 km/h. Other sizes are available upon request.The equipment is constructed with one main application box covering a range of line widths, either 0 - 20 cm or 20 - 30cm. The screed box equipment is mounted directly on the side of the material tank.The Borum thermoplastic screed box is available in the following widths: 10, 12, 15, 20, 24, 25, 30 cm. This means that material consumption will depend on the road surface. The material coming out of the box will fill up any holes, pores, or other types of road imperfections. The material pressure is by gravity only and this is how the material is poured in the marking box. ![]() The contact points determine the line width. With this type of screed application, the box is dragged with constant contact to the surface. The screed box can apply flat lines, long flex, and ribs over a line in one pass.
