灰分对TLA改性沥青性高低能影响研究

特立尼达湖沥青(TLA)中含有约35%～37%的矿物质细颗粒(灰分)。由于灰分密度比纯沥青密度大,TLA改性沥青成品在储存和运输过程中易产生灰分离析,从而导致其使用性能劣化。为此,文章结合佛山-环城际快速干线TLA改性沥青路面的施工,围绕灰分对40%TLA改性沥青混合料的性能影响进行了系统的理论分析和室内试验,从而提出灰分的控制指标及施工建议。

Impact on High Mental Deficiency of Modified Pitch of TLA of Ash Content

Contain about 35%7% of the detailed particles of mineral substance in TLA (ash content). Because the density of ash content is more big in density than the pure pitch , TLA is changed the sex pitch finished product is apt to produce the dust to separate and analyse in the course of storing and transporting, thus cause its serviceability degradation. For this reason, gentle the chapter combines FoShan- the construction on border fast arterial TLA modified pitch road surface around the city,mixes 40% of the T...
