title: Low temperature properties of UV aged asphalts containing layered double hydroxides modifier.
abstract: BACKGROUND
  In recent years, ultraviolet (UV) ageing of asphalt has attracted worldwide attention from researchers in the asphalt field. The UV radiation can result in the ageing of asphalt and thus influence its performance. So far, a variety of UV blocking materials have been investigated.
  
  
  OBJECTIVE
  In this paper, layered double hydroxides (LDHs) were introduced as the UV blocking materials into three different asphalts (S70, S90 and SBS modified asphalt).
  
  
  METHODS
  The low temperature properties, such as equivalent breaking point (EBP) and fatigue factor were tested and applied to estimate the UV blocking effects of LDHs on asphalts.
  
  
  RESULTS
  The experimental results demonstrated that LDHs could effectively reduce the ageing index of S70 and S90, and lower the degradation rate of SBS modifier.
