Abstract

The invention is a sealant special for sealing cracks of bituminous pavement, it contains (in weight share): petroleum pitch 100 shares, SBS 9-15 shares, tackifying resin 4-10 shares, antiageing agent 0.2-1 share, synthetic rubber 0-4 shares, stabilizer 0.15-0.45 share, softening agent 2-16 shares, viscosity-regulator 2-15 shares, antistripping agent 0.2-0.5 share, and reinforcing agent 35-60 shares. It has weak temperature sensitivity, strong adhesion and good elasticity.

Description

technical field [0001] The invention relates to a road crack sealant which is specially used for crack filling and sealing of asphalt pavement cracks. Background technique [0002] The traditional filling and sealing of pavement cracks is to pour ordinary petroleum asphalt into the cracks by heating and melting. Due to the strong temperature sensitivity of asphalt, it becomes soft and flowing in summer, and is carried away by the wheels, and becomes hard and brittle in winter, loses elasticity, and cracks. It is very uneconomical to refill the joints in the second year. [0003] In view of the above problems, the present invention provides a new formula technology, the purpose of which is to overcome the shortage of asphalt used for road surface crack sealing, and provide a high-performance road crack sealant, which will not soften and deform at high temperature, and will not be damaged. The wheel is taken away, it has high elasticity and does not crack at low temperature, ...
