Description
Technical field
Prevent conservation technology field the present invention relates to bituminous paving, the new spray-up of the very thin maintenance guarantor of espespecially a kind of novel nano and
Its construction technology.
Background technology
Early experience learns that bituminous paving is completed to construct and be used under normal driving conditions, after several years, even if road
Face is not there is a phenomenon where serious blow but road surface can still start slight fatigue cracking, loss fine aggregate occur, and causes it
Seepage of water is also cracked with road surface and is improved, and surface gathered water can enter pitch and mix by crack or fine aggregate injury region/undisguised place
It closes in material, double influence further accelerates the damage on road surface, however is damaged initial stage, and road surface is in normal period can be just
Often traveling, if but miss and most preferably remedy the phase, then it can lead to the pavement destructions such as more serious check crack, cracking, pit-hole.
To solve the above problems, enforceable effective ways include micro-surface area, thin cover etc., and most suitable method is mist
Sealing covers, expense are also cheaper；Mist sealing is suitable for the diseases such as surface generation infiltration, oil-poor, microscopic checks and aging is tight
The asphalt pavement of highway maintenance of weight, is a kind of express highway Preventive Maintenances of Asphalt Pavement, is set using special
For the oil-type mist sealing material that will have excellent permeability, equably spread is on bituminous paving, to play waterproof and inhibition
Loose effect prevents road surface aging, ensures the effect of traffic safety, avoids Moisture Damage, reaches protection pavement structure, extends road
The purpose of face service life.
Therefore, mist sealing covers are that sexual valence is relatively high in bituminous pavement preventive maintenance, early prevention maintenance is most effective
Measure, be also widely applied, but in application practice, the either common mist sealing of mist sealing, reducing agent mist sealing are also
It is the sealing of mist containing sand, all there are two great defects, is on the one hand that used material adhesion can be poor, causes to be laid on
It is also easy to fall off after bituminous paving；On the other hand it is the construction depth reduction on former road surface, i.e. frictional force reduces, and there are larger safety
Hidden danger.
