Description
Technical field
Patent of the present invention belongs to hard pitch technical field of modification, is specifically related to a kind of composite modified hard pitch and preparation method thereof.
Background technology
Increase is carried and traffic channelling is day by day serious and by the impact of the factor such as Pavement Design and megathermal climate along with the increase of the volume of traffic, automobile shafts, there is the diseases such as serious rut, cracking and spalling in bituminous pavement, wherein rut phenomenon has become one of the most serious collapse mode of current bituminous pavement, has had a strong impact on bituminous pavement traffic safety, service level and work-ing life.
At present, the rutting resistance improving asphalt mainly contains following two kinds of modes, and one is prepare low-grade gilsonite by techniques such as straight run, oxidation and solvent extractions, but prepared pitch low-temperature performance is generally poor; Another prepares modifying asphalt by interpolation properties-correcting agent to improve its rutting resistance, but conventional modification price general charged is higher, and higher to its technical requirements, therefore on promoting the use of, has limitation.
Hard pitch is as the low-grade heavy traffic paving asphalt of one, there is low penetration degree, high softening-point, there is good high-temperature stability, to the high temperature rutting resistance improving asphalt, there is the advantages such as good effect high stiffness, high viscosity, simultaneously cheap, raw material sources are extensive, simple and easy to get, thus concerned.But in the prior art, US4371401 proposes and uses that penetration degree is 5-201/10mm, High Modulus Asphalt Mixture prepared by the softening temperature gilsonite that is 70-90 DEG C and specific aggregate.CN104711014A proposes employing straight run-deep drawing-oxide compound technique and has prepared high temperature Rut resistance and the low temperature cracking resistance ability that No. 20 gilsonite can improve bituminous pavement.Although above technology improves the rutting resistance of bituminous pavement to a certain extent, but owing to not carrying out any processing and modification to it, except having hard feature, other side is difficult to meet its service requirements, reasonable high-temperature behavior may be had in the early stage, but not there is good low-temperature performance, antifatigue and the performance such as anti-aging.Therefore, the raising of road pavement overall performance is limited.
Hard pitch is prepared by the mode of modification, as CN101492570B has prepared a kind of hard road bitumen compositions with gilsonite, tenderizer, properties-correcting agent and matrix pitch, it has excellent high-temperature behavior, anti-fatigue performance and the adhesivity with aggregate, but analyzes less to low-temperature performance.CN20110132518 uses rubber powder and the composite mode of SBS to prepare composite modified low grade pitch, and prepared modifying asphalt has good high-temperature behavior, but high temperature viscosity is large, mobility is poor.Contriver relate to the preparation of the composite modified hard pitch of SBS/ rubber powder at paper " preparation of composite modified hard pitch and microtexture ", but its preparation technology and performance also exist some defects, especially all need further improvement in low-temperature performance and hot storage stability.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of composite modified hard pitch is Rut resistance, cracking resistance, antifatigue, the composite modified hard pitch that ageing-resistant, temperature flowing is good; Another object of the present invention is to provide the preparation method of composite modified hard pitch, and step is simple, easy handling.
