Due to increasing rapidly of the volume of traffic, vehicle maximizes, and overload is serious, vehicle channelization etc. so that bituminous paving face
Facing baptism, to this end, people start to be modified Colophonium, to meet demand, existing asphalt modification is many with rubber or tree
Fat carrys out modified pitch, but still can not meet needs, and the early damage situation such as rut, cracking, pit still can occur, this
Bright through substantial amounts of experimentation, by the mixture of rubber and resin is first carried out modification, then coordinate other to assist
Colophonium is modified processing by material again, changes the physical features of Colophonium, caking property, response to temperature and durability, it is possible to pole
Big improves Colophonium extension ability in uniform temperature environment such that it is able to adapt to more weather, further, it is possible to make to change
The film thickness of the asphalt binder after property is brought up to 28 μm by 5 μm of matrix pitch so that modified asphalt binder energy
Form thicker adhesive film in surface of aggregate, improve surface adhesion performance, can drop by adding a certain amount of adjuvant
The temperature sensitivity of low Colophonium, not only increase Colophonium ability of anti-deformation at high temperature, further improves Colophonium at low temperatures
Viscoelasticity and ductility, it is to avoid matrix pitch or single rubber and resin modified Colophonium often present under low temperature state
Vitrification brittle failure phenomenon.
The invention has the beneficial effects as follows: modified pitch of the present invention decreases the consumption of matrix pitch, reduces engineering cost.
The addition of modifying agent and adjuvant solves the poor high temperature stability that substrate often has, the problem that low-temperature ductility is little, and improves anti-
Ageing properties.Modified Colophonium finished product can reach national regulation requirement, can be used for the high road pavement construction of the multiple weather of Colophonium,
Easy and simple to handle, suitable large-scale promotion.
