Performance Evaluation of Melting-Blown Color Pavement Method

With the improvement in standard of living as well as economic growth, unlike the past, the importance of environmental and aesthetic aspects of construction structures is now greatly emphasized out of change of environment recognition. In particular, color pavement is generally applied to walks at park, sidewalk, bicycle path, parking lot and etc. in order to improve the appearance of cities. Similarly, as for roadway(car lane), color pavement is applied to crosswalk, road in front of school, section with high accident rate and etc. in order to inform clearly drivers of dangerous section. In addition, in order to smooth transportation, dark red color pavement is applied to bus lane which prohibits other cars except for bus from entering or no parking/stopping zone, and its application is expanding continuously. Color pavement applied to roadway should meet requirements such as color retention, security of skid resistance and durability. However, current color pavement technique applied in Korea doesn't satisfy above requirements because of separation of aggregate, suspension of pigments, decoloration of surface and so on, accordingly cost of social loss has been increasing. To solve these problems, construction technique should be developed for securing excellent construction property through workmanship and mechanization equipment to guarantee durability with innovative improvement of materials. Through this development color pavement technique should be secured corresponding to social needs. Based on melting-blown road marking paint technique, this study examined manufacturing of advanced ultra-thin layer color pavement composite and construction technique which increases durability and skid resistance by mixing rubberbased resin and hard aggregates based on road marking paints, and evaluated performance of pavement technique suggested in this study. As a result, composite satisfied standard of quality in melt-type road marking paints, and skid resistance experimented before and after construction resulted that skid resistance was improved after construction (applying this composite). In addition, water permeability maintained more than 80% before and after applying meltingblown advanced ultra-thin layer color pavement, accordingly it is considered that there is no problem to maintain its function when applying it to porous pavement block.
