It draws studies have shown that the cementation of fissures is highest one kind of cost performance in all slits maintenance method.Common gap-grouting material currently on the market
Mainly there are three categories：Heat use pitch class, colod-application pitch class and functional tree lipid, wherein it is hot with pitch class due to its is cheap,
It requires low reason most widely used operating personnel, accounts for about the 85% of gap-grouting material, colod-application pitch class application is taken second place, functional resin
Class application is minimum.But there are two significant deficiency needs to overcome for this currently used three categories material：Gap-grouting material is easy when high temperature
It is extruded crack and is traveling vehicle and take away；Gap-grouting material easily cracks with sides of fracture generation again when low temperature.The two significant deficiencies
Producing reason is：Gap-grouting material chassis less construction itself does not have intensity substantially, is not had at crack and transmits load force
Effect, so when high temperature road surface expands, gap-grouting material is just extruded crack and fails；Gap-grouting material and sides of fracture adhesiveness
Energy difference is the main reason for causing gap-grouting material to crack again with sides of fracture.
Since alkaline bone material is in alkalinity, pitch is in acidity, so can generate very strongization between alkaline bone material and pitch
It learns key effect and keeps the adhesive attraction power between it very strong, this is also why current most bituminous paving is using alkaline bone
The reason of material.Gap-grouting material common currently on the market noted earlier is all blanket, is there is no a kind of gap-grouting material
It is researched and developed for alkaline bone material asphalt pavement crack, this is also that gap-grouting material is caused to be repaired with alkaline bone material asphalt pavement crack
A bad major reason of maintenance effect.
In view of common gap-grouting material currently on the market, there are the significant deficiencies of self-strength difference and adhesion property difference, and simultaneously
The characteristics of not being directed to alkaline bone material bituminous paving carries out the special designing of gap-grouting material.The present invention proposes that invention is a kind of for alkalinity
The matrix type gap-grouting material of aggregate bituminous paving.Such gap-grouting material is designed for alkaline bone material bituminous paving, by adding
The more carboxyl organic matters entered improve the adhesive attraction with bituminous paving neutral and alkali aggregate；More carboxyl organic matters can also by with it is useless
The effect of old rubber powder and skeleton conditioning agent forms skeleton structure.Such matrix type gap-grouting material for alkaline bone material bituminous paving
Two significant deficiencies for improving common gap-grouting material at present simultaneously, are a kind of pavement seam filling materials with broad prospect of application
Material.
