<P>Road maintenance units each province cement concrete pavement joints mechanical maintenance work and more attention, which will more longevity for the national road,our company various studies have been done in the conservation industry,and contribute their strength,so,through a number of studies,show on the road the rational use of machinery and equipment pouring job is to make the road to ensure the performance of joints,it is to make the pavement performance of normal play important means,so we will make a comparison.</P>
<h3>Fill filling jobs in the traditional sense</h3>
<p>1.Traditionally, on the newly paved concrete road expansion joints were filled filling job,most artificial hot asphalt poured directly,such labor-intensive, poor job image,and the cracks in the asphalt melts into summer,whereby the wheel was taken away,it is break easily disengaged sclerosis in winter.It is generally less than one year have not been pouring material (asphalt),make joints lose their function.</p>
<P>2.Usually cement concrete pavement joints Maintenance,due to insufficient investment,or because of defective caulking material selection, clear, pouring equipment is not in place,no clear specification of pouring operations,resulting in some joints is raised,will easily lead to these pavement cracks, subsidence, Slabs broken and waited in vain for Disease,early damage caused</P>
<h3>Operation crack sealing machine pouring device</h3>
<h3>First:Slotted</h3>
<p>Must be slotted,our company have been convincedwithout slotted pouring pointless pouring.Second:Slot size recommendation2cm depth (the deepest of 3 cm)1.3-2㎝ width (maximum width of 5 cm)(Deep groove along the irregular fracture direction out of equal width, etc.)</P>
<h3>Third:Cleanup slot</h3>
<p>⑴Blowing crack(hair dryer, forest fire extinguishers).⑵Cracks can be used wet heat gun handle.</p>
<h3>Use heat gun effect:</h3>
<p>a.Dry, b.Heating (7 ℃ or less).</p>
<h3>Different Traditional crack sealing machine technology</h3>
<p>1.Not waterproof:The elastic restoring force of ordinary asphalt and poor adhesion,not achieve waterproofing.</p>
<p>2.High cost :From short term,traditional machine is cheap,professional pouring into large;from long term,and professional life pouring time job can be up to 5 years.</p>
<p>3.Repeat Construction:Long road worker jobs,increase in traffic accidents,traffic increased pressure.</p>
<p>4.not environmentally friendly:high temperature low temperature resistance material difference,material loss caused pollution on the road.</p>
<p>5.Life is short,it is need pouring every year</p>
