Crack router pouring primarily for processing medium and large cracks and cracks appear in the road repair after emerging,for preventive maintenance on Surface Defects.By slot machine crack after notching,with heat gun or hair dryer in the tank to blow dust and debris,Road Router Crack crack sealing machine and then pouring the sealant into the cracks,then repair cracks,and to ensure that the overall performance of the road,extend the life of the road.
Slotted repair method is suitable for small cracks,which is a common fracture treatment abroad,the main equipment used include slot machines and irrigation sewing machine,with heat gun or hair dryer auxiliary,the material used to fill joints designed for crack repair sealant material (polymer modified asphalt). Usually pay attention to the slot,Development of road maintenance grooving machines slotted size of at least 1 cm wide,1 ~ 3 cm deep,slot depth to width ratio should not exceed 2: 1,depth ratio as low as possible.
With Notch Pouring construction process Treatment pavement crack repair method:
一、Prepare work
Check the slot machine irrigation sewing machine,ensure their good technical condition,depending on the circumstances of pavement cracks,confirm fill joints design.Crack sealing machine to start heating tank sealant add sealant,the sealant is heated with stirring to 193 ℃,not exceed 204 ℃;During the heating irrigation sewing machine in the back of a truck trailer,and the sealant side of the road, safety instructions signs,Anti Oxidation infrared asphalt equipment slot machines and shoulder mounted hair dryer or heat gun mounted on a truck, etc.Drag a predetermined construction site,the half closed as highway construction zone demi.
二、Slotting
According to the design of the slot size,pre-adjusted slot machine slot depth,then slotted the job, in the process of construction,crack width according to the type of case,timely adjustment slot size,pouring meet the minimum requirements.
三、Clean slot
With a hair dryer or heat gun dust and debris inside the tank cracks on both sides at least 10cm wide, thoroughly cleaned,be clean and dry,suitable pouring temperature operation plane.
四、Pouring
(NOTE:if the temperature is below 5 ℃ fill joints,crack sealing machine to be equipped with a heat gun off the heating tank,if not at this temperature for heating tank,it will reduce the road crack sealant adhesion;if you fill joints at temperatures above 5 ℃,it may be heated,usually fill joints after heating effect is better).After the construction temperature reach the sealant,By pouring gun uniform poured into the sealant groove,Road Construction product thermal regeneration equipment and pouring machine gun with a blade head,the excess material can be scraped away,so that both sides of the crack formation equivalent to the width and thickness of the seal tape.
五、Open the traffic
After using the road crack pouring sealant,sufficiently cooled in the road crack sealant and debris on the road after a clean sweep,then open the Traffic,typical cooling time of 15 minutes,specific traffic opening time can be flexible according to the temperature conditions.
