| Abstract: | To apply waste rubber powder and SBS for asphalt modification shows not only great economic benefit, but also excellent road performance of composite modified asphalt. The skeleton-dense intermittently embedded-gradation is applied in test section of southern No.3 Ring Road project in Wuhan for proportion design, and the construction quality is strictly controlled. After more than a year＇s observation, no cracks and ruts are found. |
