What Is: Blacktop?
Blacktop (or asphalt) is a material commonly used to surface roads and parking lots as. It is a mixture of concrete together with asphalt and other minerals. Different types of asphalt concrete have different characteristics in terms of surface durability, tire wear, braking efficiency and roadway noise. The laying of Blacktop must be done while the asphalt is sufficiently hot, near 300 degrees Fahrenheit. Factors that cause Blacktop surfaces to deteriorate over time include construction quality, environmental factors such as heat and cold, and use. The life of Blacktop or Asphalt concrete can be prolonged through good design, construction and maintenance practices
