Background technology
With the fast development of national bituminous pavement, it is functional is more and more paid attention to.High-viscosity modified asphalt is mainly used in antiskid draining wearing course (OGFC road surface), bridge surface waterproof layer, stress absorbing layer (concrete or steel bridge face waterproof), " paracetamol " improvement project (absorption of stress interlayer) as modified bitumen product of new generation.High-viscosity modified asphalt viscosity is big, and elastic recovery capability is good, and 60 ℃ of viscosity can obviously reduce the reflection crack expansion greater than 20,000 Pa.s, improves bituminous high-temperature behavior, low-temperature performance, damage by water evil performance, fatigue property.
Owing to have differences such as molecular weight, viscosity between properties-correcting agent and the pitch, make the high-viscosity modified asphalt difficulties in dispersion, in addition, owing to have vinylbenzene in the elastomerics, it dissolves difficulty in pitch, cause polymkeric substance not good to the bituminous modified effect, has influenced the performance of high-viscosity modified asphalt.
In order to solve the viscosity problem of asphaltum with high viscosity, each patent adopts the principal mode of thermoelastic gonosome (SBS, SIS, SEBS) composite petroleum resin as main body properties-correcting agent basically.SBS refers to that thermoplastic elastomer, SEBS refer to styrene-ethylene/butylene-styrene block copolymer, and SIS refers to styrene isoprene styrene block copolymer (SIS).
CN200510112315.6 discloses the composite modified asphalt that is used for OGFC of a kind of SEBS of comprising, petroleum resin, polyethylene wax, but the penetration degree that requires matrix pitch is 300, and that penetration degree is 300 matrix pitch is uncommon, therefore need to add a large amount of perfume oil or machine oil matrix pitch is in harmonious proportion, make troubles to technology.
CN200810207297.3 discloses the asphalt modifier with high viscosity of a kind of SIS of comprising, coumarone indene resin, amine hydroxybenzene, and its thermostability is relatively poor.
CN200510023227.9 has put down in writing a kind of asphalt modifier with high viscosity, is made up of SBS, petroleum resin, diatomite, though high-temperature behavior has improvement, but low-temperature performance is relatively poor.
But the asphalt modifier of these patents or asphalt modification method also exist and fail fully to solve properties-correcting agent dissolves difficulty in pitch problem.
