For the performance detection of asphalt, but specification has no the marshal piece on half-flexible pavement material both at home and abroad at present
The relevant regulations of forming method and step.At present in laboratory, conventional two methods prepare half-flexible pavement material Marshall
Test specimen, a kind of method are to be molded porous asphalt matrix test specimen using conventional Marshall die trial, after cooling directly
Grouting material is poured into, grouting material is stripped after condensing with ingot stripper, the bullet between Marshall die trial and base due to routine
Property sealing is bad, easily causes slurries to leak outside in filling process, causes grouting material in porous asphalt matrix
In can not fill closely knit, and during demoulding, due to the particularity of semi-flexible test specimen structure, the huge active force of ingot stripper holds
It is easily caused in test specimen and produces micro-damage, serious even can causes grouting material mutually to be peeled off with asphalt, after having a strong impact on
The result of continuous experiment.The conventional another method for preparing half-flexible pavement material marshal piece of testing crew is had a rest using horse
You are molded porous asphalt matrix marshal piece by compaction test apparatus, are first stripped after cooling, then in test specimen surrounding
And bottom parcel plastic sheeting, cement-based grouting material is poured into from test specimen upper surface, film is torn i.e. after grouting material condensation
It can obtain semi-flexible material marshal piece.Though this method can protect grouting after test specimen from ingot stripper active force influence,
But this method complex steps, time and effort consuming, film parcel test specimen imprecision cause spillage phenomenon can also occur in filling process.Fill
After pulp material condensation during plastic sheeting is removed, film easily sticks together with grouting material, it is not easy to removes film
Totally, the result of follow-up test is influenceed.
