آسفالت رنگی در زندگی روزمره کاربردهای مختلفی دارد. Moxon
آسفالت رنگ روشن را برای سطح سد در فرانسه به کار برد. آسفالت رنگی از
طریق منعکس کردن نور ماوراء بنفش از سطح به عنوان روپوش آب بند گرم به
کار می رود، بنابراین در نور ممتد خورشید دما را 5 تا c ْ 10 کاهش می

Abstract
Colored asphalt pavement can create
better visual setting as well as improve the safety and smoothness
of driving. In this research, colored asphalt samples with various
amounts of dye are examined to study the surface color changes at
different aging periods. Distributions of surface colors on the
samples are analyzed in both the RGB and HSI color spaces. Two
types of dyes, green and red, with five different ratios are mixed
with clear asphalt to make colored asphalt samples. The samples are
exposed to ultraviolet light in the QUV tester for five different
aging spans. Results show that the amount and type of dye added,
and the different aging spans affect fading in the colored asphalt.
Results also indicate that clear asphalt mixed with 5% or more of
dye is capable of manufacturing better-colored asphalt. Finally,
colored asphalt with red dye showed better resistance to
ultraviolet light.
