The function of giving play to the semi-rigid material the road construction is more and more obvious, and the semi-rigid basic unit has old intensity, stability is good and characteristic that rigidity is great, have already become mainly form at the basic level in road construction of our country, therefore probe into the formation mechanism of the semi-rigid basic unit, project characteristic and construction craft.
This text material from various places to carry on analysis and research with performance primary and secondary relation of main factor to two gray broken stone emphatically, mix and not different to collect to different grade material two dust of content stabilize all way of broken stone go on comprehensive appraisal with performance, optimization design and science that it is this material have constructed and offered the useful basis. And the semi-rigid material to that some other kind are common: Cement stabilize broken stone, cement soil form basic unit or bottom material of basic unit make up and design, intensity and rigidity, doing and drawing back the characteristic, warm performance which drew back the characteristic and appraising.
Subject problem that exist go on analysis and development prospect go on, expect employ, in our country road to semi-rigid material finally.
