Embodiment Construction

[0009] (1) Weigh raw materials according to the following ratio

[0010] 30-50 parts of base asphalt

[0011] 20-40 parts of water

[0012] Rubber modifier 4-10 parts

[0013] 10-30 parts of water-based adhesive

[0014] 3-8 parts of water-based resin

[0015] Stabilizer 2~6 parts

[0016] Thickener 2~10 parts

[0017] Dispersant 2~10 parts

[0018] (2) Preparation process

[0019] Step 1: Put hot water (50-70°C), hot asphalt (100-140°C), and dispersant in the reaction kettle, start low-speed stirring (50-100 rpm), and then add rubber modifier, Water-based adhesive and water-based resin, cover the lid, stir at a constant speed for 10-30 minutes (150-300 rpm), and keep the temperature at 70-90°C;

[0020] Step 2: Open the reaction kettle, then add stabilizer and thickener in turn, cover the lid, and continue to keep warm and stir for 2 to 10 minutes (50 to 100 rpm);

[0021] Step 3: Open the reaction kettle, pour the product into the barrel and cool it to below 30°C fo...

Abstract

The invention relates to water-base joint grouting glue for a normal temperature road, namely an environment-friendly joint grouting and joint sealing material having high viscosity, high cementing power and high adhesive property, which is formed by special processes of copolymerizing water, a water-base adhesive, bitumen and a dispersing agent, then modifying a macromolecular water-soluble resinand a rubber latex, and adding the auxiliary agents of a stabilizing agent, a thickening material and the like, and can be used for treating and sealing various types of cracks of bitumen and cementroad surfaces and joint seams of cement road surfaces and bridge surfaces. The joint grouting glue is in a gel state at normal temperature, can be stirred but cannot flow, thus the joint grouting gluecan enter joints directly without slotting and cannot infiltrate downwards so as to play a role in sealing the joints; and simultaneously the joint grouting glue is soluble in water; therefore, the joint grouting glue can be mixed with water to prepare strong-permeability joint grouting materials with any viscosities, and can be effectively poured into deep parts of the cracks of road surfaces without slotting. The joint grouting glue combines the advantages of slotting and non-slotting repairing methods, and simultaneously avoids the disadvantages of the two methods.

Description

Technical field [0001] The invention belongs to the field of road joint filling materials, in particular to a water-based joint filling glue (mud) for normal-temperature roads and a preparation method thereof. Background technique [0002] Prior art: With the rapid development of my country's highway traffic, the mileage of highways continues to increase, and most of them are asphalt roads. Pavement cracks are one of the most common diseases on asphalt concrete pavement, and they are more serious among many road diseases. Generally, according to the distribution of cracks, they are divided into four types: transverse cracks, longitudinal cracks, irregular cracks and cracks. Among them, transverse cracks and longitudinal cracks are not only the two main manifestations of cracks, but also irregular cracks and early manifestations of cracks. If they are not treated in time, under the action of vehicle loads and the infiltration of rainwater, horizontal and longitudinal cracks ...
