温拌布敦岩沥青混合料路用性能研究

A Research on the Pavement Performance of Warm Mix Buton Mastic Asphalt

复合改性沥青混合料是采用布敦岩沥青(BMA)及温拌剂复合改性而成的一种沥青混合料,将它与常规BMA及常规温拌沥青性能进行比较,得出该复合改性沥青混合料可以大大降低拌和温度、节约能源、保护环境,还可保证良好的路用性能。以布敦岩沥青作为改性剂能明显提高沥青混合料的高温稳定性,但对低温性能影响很小。

Compositing modified asphalt mixture is a kind of asphalt mixture which uses Buton Mastic Asphalt（BMA） and warm modifier compound modification.It is proved that the composite modified asphalt mixture technology can greatly reduce the mixing temperature,save energy and protect the environment,and can guarantee good road performance.Employing Buton Mastic Asphalt as modifier can obviously increase the high temperature stability of asphalt mixture,with little impact on low temperature performance.
