Joint-filling adhesive and road-joint repairing process applying same

Abstract

The invention discloses joint-filling adhesive and a road-joint repairing process applying the same. The joint-filling adhesive is characterized in that the joint-filling adhesive is prepared from themain components: petroleum asphalt, petroleum resin and alkyd resin with the proportion being (2-2.2):(1-1.5):(0.1-0.3), and in operation, the temperature is controlled to 180-195 DEG C all the time.A special hot-melting kettle provides high-temperature joint-filling adhesive in operation, the temperature is controlled to be 180-195 DEG C, and the mean temperature difference is within + / -3 DEG C, so that the complete filling of telescopic joints can be ensured; simultaneously, the joint-filling adhesive adopts petroleum asphalt, petroleum resin and alkyd resin as main components, the viscosity of the joint-filling adhesive can be controlled to be 360-390mPa.S, and the fluidity is better. The road-joint repairing process applying the joint-filling adhesive has the beneficial effects thatfast repairing for small joints of roads is realized, the service life of the road is prolonged, and the maintenance cost is reduced; simultaneously, due to dustless operation, the operation environment is greatly improved.

Description

【Technical field】 [0001] The invention relates to road maintenance and repair materials and the technical field, in particular to a gap filling glue and a road gap repair process using the same. 【Background technique】 [0002] All kinds of cracks on the cement pavement will affect the appearance of the road and reduce the service life of the pavement. There are problems and other problems that cause cracks in the road surface, which in turn causes water on the road to enter the base layer through the gaps. It is possible that the water will take the soil layer of the subgrade, and it may also form mud with the soil layer, which will be squeezed out when the vehicle rolls over the gaps in the road surface. Cause road surface damage and shorten the service life of the road surface. In today's increasingly noisy traffic conditions, it may further deteriorate, and the long-term road repair project will cause traffic congestion, and the dust in the construction will pollute the e...

[0002] All kinds of cracks on the cement pavement will affect the appearance of the road and reduce the service life of the pavement. There are problems and other problems that cause cracks in the road surface, which in turn causes water on the road to enter the base layer through the gaps. It is possible that the water will take the soil layer of the subgrade, and it may also form mud with the soil layer, which will be squeezed out when the vehicle rolls over the gaps in the road surface. Cause road surface damage and shorten the service life of the road surface. In today's increasingly noisy traffic conditions, it may further deteriorate, and the long-term road repair project will cause traffic congestion, and the dust in the construction will pollute the environment, and repeated repairs It cannot be maintained for a long time, and the cost of road maintenance will increase. Currently, asphalt is commonly used for road repair, but its adhesion and flexibility are poor, and it is not resistant to high and low temperature changes. Road joint glue, also known as road sealant and road joint filler , to modify the asphalt, mainly used for the repair of road surface cracks, the pouring process is simple
