JX-113 Road bridge polymer modified asphalt waterproof coating is a new type of environmental protection waterproof coating based on petroleum asphalt, selected a variety of high quality polymer as the composite modifier by scientific formulation. The coating has excellent heat resistance, adhesion and shear resistance, and good compatibility with petroleum asphalt products, can fully meet the special requirements of asphalt concrete bridge deck waterproof, waterproof performance durable and reliable, is all kinds of Bridges and viaduct surface waterproof construction special coating.

Basic surface inspection, cleaning, local repair, coating JS waterproof coating bottom, Yin Angle, Yang Angle and other parts to strengthen treatment, coating JS waterproof coating first time, laying a non-woven cloth, coating JS waterproof coating second and third time, completion acceptance. On the slope, the long side of the non-woven fabric should be perpendicular to the direction of drainage, and laid sequentially along the opposite direction of drainage; In the corner and facade, non - woven fabric should be bottom - up shop. When JS coating is applied in large area of construction, pre-lay non-woven fabric 5m ~ 10m at the laying site before pasting, find the right direction, fix it in the middle, and then roll it up to brush the prepared JS waterproof coating bottom, and immediately lay the cloth after the initial setting of the bottom coating. Construction personnel should be careful, JS coating base thickness to uniform. Non - woven fabric should be glued without empty drum, fold, paste area should reach more than 85%. Nonwoven fabric using JS paint paste nonwoven fabric. Waterproof shear wall works from bottom to top.

(1) the basic course must be flat, with surface strength, and shall not have defects such as loose, crack, empty drum, sand rise and pit, etc., and shall be cleaned up.

(2) the bottom coating ratio of JS waterproof coating is m(liquid material) : m(powder material) : m(water)=10:7:14. Mix ingredients evenly, do not have dry powder particles. Besmear brush wants even, must not have leakage besmear, much besmear phenomenon, put an end to flow to drop.

(3)JS waterproof coating construction should be the first to Yin and Yang Angle and other local additional layer to strengthen the treatment, the additional layer width of 500mm, 250mm on each side.

(4) paint JS waterproof coating for the first time, the material ratio is m(liquid material) : m(powder material) : m(water)=10:7:0.2. Besmear brush wants even, compact. JS coating requires a firm bond with the base, no empty drum, peeling, cracking and other phenomena.

(5) lay non-woven fabric once, do not have empty drum, warping edge phenomenon, long side lap not less than 70mm ~ 100mm, short side lap not less than 100mm ~ 150mm.

(6) spreading JS waterproof coating and the second time and third time, ratio of material to m (liquid) : m (powder) : m (water) = 10:7, 0.2. Coating brush should be uniform, dense, each coating direction should be perpendicular to each other, achieve waterproof coating thickness, finished coating thickness of 1.2mm ~ 1.5mm.

(7) inspection and repair: after the construction is completed, check the waterproof layer immediately after the conjunctiva of JS waterproof coating. Use a knife to cut small pieces and actually measure the thickness of the waterproof layer. Check one place according to 100m2, increase the number of brush times for coating film thickness not up to the requirement, until it reaches the thickness, the thickness can only be accepted.

(8) details: all corners and complex parts should be paved with additional layers. The method of adding layer at the junction of flat elevation.
