Anderson Asphalt is one of a few companies world-wide with the ability to provide machine laid bridge deck surfacing of mastic asphalt.

This material has been specially developed for steel decked suspension bridges, which are often exposed to vibration and movement due to temperature variations, traffic loading and high winds. Not only is mastic asphalt highly flexible, it is also resistant to cracking, skid resistant and less likely to harden as a result of aging. Selection of only the best materials available provides the excellent durability. Surfacing life of more than 20 years is not unusual.

The Company used mastic asphalt on the surfacing of the Tsing Ma Bridge, one of Hong Kong's predominant landmarks and which opened in April, 1997.

Anderson Mastic (China) Limited was formed to provide mastic asphalt in Mainland China - such as for the Jiangyin Bridge on the Yangtze River.

Anderson Asphalt is at the frontier of the industry and demonstrated by its capability with respect to mastic asphalt. Similarly, with Stone Mastic Asphalt (SMA), is material has been demonstrated to be an excellent wearing course material, as a result of its interlocking framework of aggregate, thick binder film and the use of cellulose fibres. Compared to ordinary asphalt, SMA resists rutting, deformation and low temperature cracking and has enhanced noise reduction ability, good surface texture and excellent durability.
