Modified asphalt waterproof membrane for road and bridge

Modified asphalt waterproofing membrane for roads and bridges, with a polyester base, styrene-butadiene-styrene (SBS) thermoplastic elastomer, random polypropylene or random polyolefin (APP) plastic body As a modifier, it is a rollable sheet waterproof material made of insulating materials such as polyethylene film, fine sand or mineral materials on both sides. The road and bridge waterproof membrane is suitable for the surface of roads and bridges with cement concrete as the surface layer, and the modified asphalt polyester tire waterproof membrane with asphalt concrete layer laid on it. Other uses such as airport runways, parking lots, etc.

Features:

• Has all the features of APP/SBS.
• It has a high heat resistance and high-temperature shear resistance, which can ensure that the waterproof layer will not be damaged when paving high-temperature asphalt concrete.
• It has strong anti-breakage ability and can withstand the bare grinding of equipment during construction and the puncture of pellets.
• High tensile strength, high elongation, and high bonding strength with concrete.
• Non-foaming and delamination, good impermeability, able to withstand repeated driving and dynamic water pressure.
• Good acid, alkali, and salt resistance, not affected by freeze-thaw cycles. Good anti-aging performance.

Product Specifications:

• According to the construction method, the products are divided into: Z: self-adhesive construction; R: hot-melt construction; or J: hot-melt adhesive construction waterproof membrane.
• Hot-melt or hot-melt construction waterproofing membranes are divided into different modified materials: elastomer (SBS), plastomer (APP) modified asphalt waterproofing membranes; self-adhesive construction waterproofing membranes are self-adhesive as a whole, and SBS Mainly, rubber-modified asphalt waterproofing membrane with other polymers added.
• APP-modified asphalt waterproof membrane is divided into Type I and Type II according to the form of asphalt pavement. The upper surface material of the membrane is fine sand and S hot-melt construction; S: fine sand. The material of the lower surface of the hot melt adhesive construction waterproof membrane is fine sand S.

Performance index: Executive standard: (JC/T974-2005)

Storage and transportation:

• During storage and transportation, products of different types and specifications should be stacked separately and should not be mixed.
• Avoid sun and rain. And pay attention to ventilation.
• Hot-melt or hot-melt adhesive waterproof membranes should be placed upright below 50°C, and their height should not exceed two floors.
• The self-adhesive waterproof membrane can only be placed in a single layer vertically, and it can be placed flat in a box, and the height should not exceed five layers.
• Under normal transportation and storage conditions, the storage period is at least one year from the production date.
