Description
Technical field
The present invention relates to bituminous composition and preparation method thereof technical field, more particularly to a kind of bituminous composition and its system
Preparation Method.
Background technology
The colloidal substance that the asphaltene molecules group that traditional pitch is wrapped up by resin forms, it appear that very strong
Oily state (i.e. malthenes).Colloid is divided into colloidal sol (referring mainly to liquidus density) and frozen glue (referring mainly to density of solid), and this takes
The certainly poised state between its composition.For pitch, the balance of two states is depending on asphalitine and the phase interaction of interlaminar resin
With, and by the strong influence of ambient temperature.In fact, its frozen glue state has been broken in the rise of asphalt temperature, make asphaltene molecule
Group develops into collosol state.Thus a key property of pitch is exactly that solid or semisolid are showed under normal temperature, but with temperature
Rise is easily dissolved.This significant heat sensitivity is the most important feature of pitch, and its main weakness.In fact, drip
Blue or green mixture should be able to keep its good performance under annual different condition of work.Significant heat sensitivity hampers pitch
Mixture shows good performance in high temperature and low temperature, thus pitch must be modified to enhance product performance.
Production Process of Modified Bitumen direct plunges into method, parent method, mechanical mixing method etc., existing bituminous composition, storage
Deposit stablize it is poor, for fuel and oil product dissolving and etch ability it is poor, high and low temperature performance is low, can not meet people's
Use demand.
