TEMA: Horizontalna signalizacija i obeležavanje puteva

Kako mrzim te farbe za horizontalnu signalizaciju...kad ce vise poceti da koriste hladnu plastiku

Thermoplastic
One of the most common types of road marking based on its balance between cost and performance longevity, thermoplastic binder systems are generally based on one of three core chemistries: hydrocarbons, rosin esters or maleic modified rosin esters (MMRE). Thermoplastic coatings are generally homogeneous dry mixes of binder resins, plasticizers, glass beads (or other optics), pigments, and fillers. Their use has increased over paints mainly due to the performance benefits of increased durability, retro-reflectivity, and a lack of VOC solvents.
Thermoplastic markings are applied using specially designed vehicles. The thermoplastic mix is heated in trucks to about 200 °C (400 °F) before being fed to the application apparatus. This is often a screed box or ribbon gun. Immediately after the thermoplastic has been applied, glass beads are laid onto the hot material so that they embed before the plastic hardens. These beads provide initial retro-reflection. As the marking wears during use and the initial beads are lost, the beads mixed with the binder are uncovered, providing long term reflectivity. Most thermoplastic is produced in white and yellow colors, but other colors such as red may also be produced.[citation needed]

Plastics were introduced in the late 1960s and early 1970s.[citation needed] Commonly referred to as tape or cold plastic, this product is heavy-grade material with reflective beads embedded in the plastic. It is commonly used to mark crosswalks, stop bars, and traffic guidances such as turn lanes, HOV lanes, train crossings, pedestrian crossings, taxi lanes, bus lanes, and bike lanes.

Preformed Thermoplastic—Preformed thermoplastic pavement markings are applied using a propane heat torch and are used primarily because of their durability and cost-effective service life. Cut and ready to position onto an asphalt or concrete pavement surface, the most common applications of preformed thermoplastic pavement markings are found at intersections as transverse markings such as stop lines, legends, crosswalks, arrows, bike lane symbols, and accessibility symbols

Inace , dosta ulica u beogradu je oznaceno hladnom plastikom.

Ređe i noćno farbanje puteva nemoguće

Ređe, kao i noćno farbanje gradskih saobraćajnica, u Novom Sadu trenutno nije moguće.
Dugotrajnije smese kojima bi se obeležavala horizontalna signalizacija, za dužinu novosadskih puteva nisu isplative, tvrde za Radio 021 u gradskom preduzeću "Put", koje je zaduženo za ovaj posao. Takođe, farbanje nije moguće tokom noći, kaže portparolka JKP "Put", Jelena Stojsavljević.
"Ovaj posao se mora raditi tokom dana, budući da su potrebni posebni temparaturni uslovi. Znate i sami da smo do skoro imali temperaturu tla ispod plus pet stepeni, što je veoma bitno za farbanje horizontalne signalizacije. Imali smo i dosta kiše, veoma vlažan vremenski period, očekivali smo lepo vreme i temperature vazduha iznad 10 stepeni", objašnjava portparolka JKP "Put".
Noćni radovi izbegavaju se i iz razloga bezbednosti radnika, a Jelena Stojsavljević objašnjava da se kada je toplije može raditi noću, ali samo na bulevarima, jer se u manjim ulicama Novosađani žale na buku mašina kojima se na asfalt nanosi farba. Ona dodaje da radnici rade tokom vikenda i praznika, a plan je da prolećno farbanje svih važnijih saobraćajnica bude gotovo pre Poljoprivrednog sajma, ali će to zavisiti od vremenskih prilika.
Farbanje se potom nastavlja u manjim ulicama, a različitim tempom trajaće do polovine novembra. Pred početak školske godine, obavezno se rade pešački prelazi u blizini svih novosadskih škola. (D.S.)
