STONE MATRIX ASPHALT PROPERTIES RELATED TO MIXTURE DESIGN
The objectives of this Stone Matrix Asphalt (SMA) study were to: (1) find the interlaboratory average values and the standard deviations of voids in mineral aggregates (VMA), theoretical maximum density and optimum asphalt content; (2) develop a draindown test and evaluate the effects of various factors on draindown of asphalt in SMA mixes; (3) develop a comparison of laboratory densities of SMA mixes prepared by a gyratory machine to those prepared by the mechanical Marshal hammer; and (4) develop a method to evaluate stone-on-stone contact in SMA mixes.
According to Mazhai Oil Field's hostile sandstone reservoir factors,we introduce HD surfactant.Laboratory tests indicate that the HD surfactant suit high salt and high temperature oil floor,and can improve effectually oil quality.6 well times of injection well Permeability control jobs were completed,the cumulative increased oil was 2937t.Thus HD surfactant suit Mazhai Oil Field.So HD is a good oil displacement agent.
