“…The second method of application is a potential source of glass microbeads because the excessive amount of glass microbeads, which is not bound to the paint, can be more easily distributed in the roadside environment. There are two types of paints used in the road marking systems, the water-based and the solvent-based (Asdrubali et al, 2013). The first ones have longer expected service life than the solvent-based paints, but they are less environmentally friendly because they contain high levels of volatile organic compounds that contribute to formation of ozone (Burghardt et al, 2016).…”

Glass microspheres are spherical glass particles that have many applications including composite polymer material technology, medicine, analytical chemistry, abrasive blasting, paints, and coatings. They are widely used in the production of road and pavement marking materials, such as traffic paints, thermoplastics, and preformed markings. The abundance of glass microspheres in terrestrial deposits and possibly in marine sediments, as well as their physical and chemical stability, would make them a good indicator of the Anthropocene in geologic records. The Anthropocene as an epoch of the geologic timescale should be identified by the presence of specific signals in strata formed during this interval. An ideal geologic indicator of the Anthropocene should be ubiquitous in different environmental settings and should have a strong preservation potential in future strata. In this study, road dust and river sediment samples were collected in the city of Kielce (south-central Poland) and examined for the presence of glass microspheres. A large number of microspheres in the road dust samples (800-2700 microspheres/kg) suggests that the microspheres released by degradation of traffic paints may be effectively transported from the road dust to river sediments. This is evidenced by the highest number of glass microspheres found in a river sediment sample collected near street stormwater discharge (1500-9600 microspheres/kg). The occurrence of glass microspheres in the river sediments collected at about 500 m from the road where reflective traffic paints are used (200-500 microspheres/kg) suggests that these are likely to be subjected to fluvial transport.

“…Sathyanarayanan et al [28] predicts the failure of given markings with a Weibull distribution. Asdrubali et al [29] proposed the first known preventive replacement strategy for urban markings while respecting the NF EN 1436 rules [5]. Chimba et al [30] proposes a different degradation model based on a Markov chain.…”

The maintenance of road infrastructure is a classic social challenge, especially in the context of a decreasing maintenance budget and the advent of autonomous vehicle traffic. Road markings need an accurate replacement strategy to guarantee that the markings remain perceptible. The retroreflective luminance of markings is currently dynamically quantifiable only by using a retroreflectometer such as the Ecodyn from MLPC. The main objective of this research is to construct a performance-based approach for retroreflective marking replacement adapted to a given road network. This approach involves three main tasks: localize the strategic area based on past inspections, determine an adapted decay model for a given area, and evaluate the economic impact of replacing markings. This paper focuses on the first task. We apply the Agglomerative Hierarchical Clustering (AHC) method to a given dataset to obtain a suitable markings line segmentation. Markings whose retroreflective luminance exhibits similar evolution over time are interpreted to belong to a specific area of the road network. When no follow-up replacement has occurred, a replacement detector deduces the date at which markings were laid from the clusters. The broken center line of the French National Road 4 illustrates the proposed approach; the road is divided into 5 clusters and 34 lifecycles. A study of markings laid in 2008 and replaced in 2012 shows important variations in the decay of the retroreflective luminance as identified by the clustering approach. Even for a single road, an optimal replacement strategy for retroreflective road markings is necessary and is composed of several local maintenance strategies.

“…When properly applied, coldplastics dry within 20-30 minutes and with correctly selected glass beads provide high retroref lectivity. Coldplastics are used mainly on high-traffic roads and on pedestrian crossings (Asdrubali et al, 2013). They can be extruded at thick layers or as structured markings for lines and also applied by hand.…”

“…Green Public Procurement (GPP) criteria for outdoor paints and varnishes is extended to road marking materials as well. 3 A ssessment of ef fects of various road markings has not produced definitive results as to which road markings maximise safety benefits (Asdrubali et al, 2013). Field of driver attention is changing depending on the construction characteristics of the road, the traffic conditions, and the vehicle speed, generally decreasing with increase if the speed and increasing when reducing speed (Thurston, 2009).…”

Horizontal road markings are one of the essential safety features of modern roadways. All of the utilised systems consist of a pigmented coating containing partially embedded retroreflective elements such as glass beads. In addition to durability and functionality of the road marking, ease of application and effect on human health and environment are primary considerations for their selection. Road marking systems can be divided into plural component materials that cure due to chemical reaction occurring at the site of application, thermoplastics that require heat for application, and paints, drying upon evaporation of the dissolving medium. The focus of this paper is on road marking paints with a special emphasis on contemporary waterborne materials. Over 100 years old solventborne technology furnishes paints that afford consistent application properties under a variety of conditions such as lower temperatures and high humidity. Their environmental and human health impact is significant and durability quite poor. Modern waterborne paints are based on acrylic resins and incorporate developed in the 1990s quick-set chemical mechanism for drying. Under favourable weather conditions, they dry faster as compared to solventborne. However, their known weakness is risk of washout in case of rain and sluggish development of washout resistance at marginal application conditions like high humidity and low temperature. Impact of waterborne paints on human health and environment is very significantly minimised as compared to other materials. Their durability is significantly higher as compared to solventbased paints. Analysis of characteristics of waterborne road marking paints and preliminary results from their trial application in Croatia are presented herein. Based on the presented comparison with solventborne materials, after results from test application become available, intelligent decisions regarding future use of waterborne road marking paints in Croatia and other countries that have not embraced this technology shall be possible.
