Survey on the application of recycled pavement materials and WMA mixtures in the U.S. As of 20:00 on November 22, 2015, the cumulative sunshine duration of Beijing since the beginning of November was only 31.8 hours, being the lowest in the same period since 1951, while the average value of the same period was 136.4 hours in the past. In addition, many places of northern China hit historical lows in sunshine duration. Except rains and snows, heavy haze that lasts for days is a major “sunshine killer”, and removing haze becomes an urgent “gray topic”. All industries are making efforts...
