Technical field

The present invention relates to road rehabilitation fields, more particularly, to a kind of asphalt roads restorative procedure.

Background technique

Winter temperature rapid drawdown, under extraneous load action, asphalt roads works as pitch due to being influenced by temperature decline variation The part stress of road cracks when being more than Tensile strength, causes road surface to be destroyed, is repaired.

When general asphalt roads is repaired, needs to use hot in-place recycling technology method and repaired, will be damaged first Road surface heated, scarifying, mixes a certain amount of new pitch, new pitch mixture, regenerative agent etc., then through it is hot mix and stir, pave, It the processes such as rolls and carries out reparation road surface, but asphalt roads meets when temperature declines again after having repaired and is still easy to freeze It splits, causes maintenance cost higher, therefore, there are also improved spaces.

Summary of the invention

In view of the deficiencies of the prior art, the present invention intends to provide a kind of asphalt roads restorative procedure, have The advantages of reducing maintenance cost.

To achieve the above object, the present invention provides the following technical scheme that

A kind of asphalt roads restorative procedure, comprising the following steps:

S1. asphalt is configured；

S2. the road surface being damaged is destroyed to form crushable layer；

S3. asphalt is injected, specific as follows:

Asphalt is backfilled in crushable layer；

S4. it is compacted, specific as follows:

Crushable layer is compacted to form compacted lift；

S5. asphalt road surface, specific as follows:

Asphalt is laid on compacted lift to form bituminous pavement；

S6. it flattens, specific as follows:

Flatten bituminous pavement；

The asphalt includes the component of following mass fraction:

100 parts of pitch；

200-300 parts of coarse aggregate；

100-200 parts of fine aggregate；

10-20 parts of dipentene；

3-5 parts of silicon nitride；

15-30 parts of tert-butylhydroquinone.

It is to be broken by backfilling the asphalt especially prepared in crushable layer by using above-mentioned technical proposal Asphalt natural cooling in layer is further continued for asphalt mixture to form bituminous pavement, when bituminous pavement is by repairing Afterwards, when bituminous pavement chance winter temperature sharply declines again, bursting by freezing is less likely to occur asphalt roads, so that asphalt roads is without more Secondary reparation, so that maintenance cost is lower；

By the way that tert-butylhydroquinone is added in asphalt, so that the bituminous pavement of asphalt preparation is crisp Point decline so that bituminous pavement is not easy to crack, and then reduces the case where bituminous pavement after repairing frequently is repaired because of bursting by freezing, drop The number of low reparation, to reduce maintenance cost.

By the way that silicon nitride is added and cooperates at a specific ratio with tert-butylhydroquinone, so that tert-butylhydroquinone drops The better effect of the brittle point of low asphalt, so that the brittle point of asphalt further declines, so that bituminous pavement is less It is easy to crack, preferably it is suitable for severe cold area, applicability is wider.

By the way that dipentene is added in asphalt as regenerative agent, promote asphalt regenerative effect, certain journey The reinforcement intensity of asphalt on degree, so that Stability of Asphalt Concrete Pavement is preferable.
