Conclusion
.Asphalt is used for construction materials products road and sidewalk by producing rubber matoy currently is often used for crude oil as the core.Although the current engineering materials have developed rapidly, but in how some types, such as paved road that relies on a large barrier properties of water. And able to withstand the act to the material surface."Asphalt" material is the value for application. The research. Asphalt used in asphalt performance is the most AC type 60 / 70 qualified to withstand the heat and strong high.Asphalt is a material with a value more than other materials. Because if we counted if at cost more but age increasing use is worth to use
