Cold-mixed and cold-laid emulsified asphalt mixture and preparation method thereof

Номер: CN116589225A
Принадлежит:

The invention relates to the technical field of road building materials, in particular to a cold-mixed and cold-laid emulsified asphalt mixture and a preparation method thereof. Compared with the prior art, the emulsified asphalt can be stored stably for a long time, the mixture can be demulsified as soon as possible after being paved on a pavement, traffic can be opened as soon as possible, and the aggregate is wide in application range and suitable for any cold construction process of the pavement, such as micro-surfacing, sand-containing fog sealing layers and the like. The cement pavement changes white into black, is energy-saving and environment-friendly, breaks through the limitation of thermal insulation conditions in the transportation process of the traditional hot mix mixture and the strict limitation of temperature conditions in the compaction process, and is convenient to construct.

Light-guide light-gathering generating device

Номер: CN0101834548A
Принадлежит:

The invention discloses a light-guide light-collecting generating device comprising a light guide plate with high light transmittance, thin films with the effects of interference and diffraction and a light energy collector. Both sides of the light energy collector are glued with the thin films, light rays with different incident angles are irradiated behind the thin films at both sides of the light energy collecting part through the light guide plate, the thin films modulate the amplitude and the phase of the incident light and changes the transmission route of the incident light so that the deflection of light paths is realized, and the defected light rays enter the light guide plate, are conducted in the light guide plate through full reflection, and then are gathered on the light energy collector together with the incident light rays on the light energy collector. The light-guide light-collecting generating device has the advantages of simple structure, large receiving angle, low cost ...
