Embodiment 1

[0016] The following porous resin sealing layer is used on the asphalt pavement of a certain municipal road, and the porous resin sealing layer is manufactured according to the construction process.

[0017] (1) Material formula

[0018] per 1m 2 The composition materials of the porous resin seal layer are: 1.6kg cementing material, 4.5kg main aggregate and 2.0kg pore-forming aggregate. Among them, the cementing material adopts two-component polyurethane. The main aggregate is made of ceramic particles with a particle size in the range of 1.0mm to 2.0mm. According to the T0350-2005 method in JTG E42-2005 "Highway Engineering Aggregate Test Regulations", the crushing index of the main aggregate is 15%. The pore-forming aggregate is made of ceramsite, and the particle size is in the range of 2.0mm to 4.0mm. According to the T0350-2005 method in JTG E42-2005 "Highway Engineering Aggregate Test Regulations", the crushing index of the pore-forming aggregate is determined to b...

Embodiment 2

[0033] The following porous resin sealing layer is used on the cement pavement of an outdoor parking lot, and the resin sealing layer is manufactured according to the construction process.

[0034] (1) Material formula

[0035] per 1m 2 The composition materials of the porous resin seal layer are: 0.8kg cementing material, 3.0kg main aggregate and 1.0kg pore-forming aggregate. Among them, the cement adopts two-component epoxy resin. The main aggregate is made of ceramic particles with a particle size in the range of 1.0mm to 2.0mm. According to the T0350-2005 method in JTG E42-2005 "Test Regulations for Highway Engineering Aggregate", the crushing index of the main aggregate is 5%. The pore-forming aggregate is made of ceramsite, and the particle size is in the range of 3.0mm to 4.0mm. According to the T0350-2005 method in JTG E42-2005 "Highway Engineering Aggregate Test Regulations", the crushing index of the pore-forming aggregate is determined to be 80%.

Abstract

The invention provides a road surface porous resin seal layer and a construction method thereof; in the road surface porous resin seal layer, a binder is used for binding monolayer aggregate, and the thickness of the seal layer is 2mm to 6mm; the aggregate comprises main aggregate and pore aggregate, and every 1m<2> of porous resin seal layer contains 0.8kg to 2kg of binder, 3.0kg to 5.0kg of main aggregate and 1.0kg to 2.5kg of pore aggregate; and the pore aggregate is uniformly distributed among the main aggregate. The pore aggregate is uniformly scattered on a dry original road surface; the binder is sprayed, and the main aggregate is uniformly scattered among the pore aggregate before the binder is cured; and after the binder is fully cured, the pore aggregate is crushed by a steel drum road roller and the crushed aggregate is swept, and the porous resin seal layer is completed. After the porous resin seal layer is paved on the road surface, the rainwater which penetrates into the ground surface can be increased, so that the urban drainage burden is reduced, and a series of urban environment problems, such as the sharp fall of underground water level, 'heat island effect' and the like are mitigated.

Description

technical field [0001] The invention relates to a road pavement material and a manufacturing method thereof, in particular to a porous resin sealing layer on the road surface and a construction method thereof. Background technique [0002] The existing resin-based sealing layer generally adopts the process of evenly coating the resin-based cementing material on the completed road surface, and then spreading a single layer of wear-resistant hard aggregate to make it consolidated in the resin. The thickness of the resin sealing layer is less than 1cm. After the resin sealant is applied, the anti-skid performance of the original pavement can be improved; when the colored aggregate is used, it also has the landscape effect of colored pavement. [0003] The problems existing in the existing resin sealing layer are that there are few pores and the permeability coefficient is small. After the resin sealing layer is implemented on the water-permeable pavement, the surface pores of...
