Experimental Investigation and Applied Research of Permeable Marking for Porous Asphalt Wearing Course

CODEN: ACEMF9

Abstract

Porous asphalt wearing courses are a type of high-performance wearing course with technical features such as high skid resistance and low noise, as well as abilities that inhibit water mist during rainy weather conditions, prevent skidding during high-speed driving, and alleviate dazzle light during night driving. With the gradual popularization of this high-performance wearing course in China, the problem of its matched markings has become a growing concern. Hot melting scrape coating markings are commonly used in porous asphalt wearing course designs. However, this marking technology has associated problems. For example, its application often blocks the pores of the porous asphalt and causes surface water to gather on rainy days. It also attenuates the functional properties of porous asphalt. Additionally, material consumption increases because of marking infiltration. The proposed permeable marking technology addresses issues of performance concerning drainability, high skid resistance, and all-dimensional and all-weather reflection. Technical problems, such as pore blockage from ordinary markings, are successfully resolved by using an active bicomponent marking material through its reaction into membranes and in combination with rotating-coating type or discontinuous-extrusion type marking application technology. From the laboratory and in situ tests, it was determined that adhesion, reflection in the dark, wet driving conditions, and pavement skid-resistance value from the marking are improved.
