<P>(1) synchronous gravel seal layer is a certain thickness of the asphalt film (1 ~ 2mm) bonded ultra-thin asphalt gravel surface treatment layer, the overall mechanical characteristics of the flexible, can increase the road crack resistance, Crack, reduce road surface reflection cracks,<a href="http://maintenancemachineprice.com//crack-repair/ireland-pavement-road-construction.html">ireland pavement road construction</a> improve road surface impermeability performance, for road maintenance can extend the service life of more than 10 years, if the use of polymer modified binder better.</P>
<P>(2) the simultaneous gravel seal can greatly improve the friction coefficient of the original road surface, that is, increase the anti-slip performance of the road and make the road surface roughness to a certain degree of recovery; through the use of local multi-layer paving different size stone construction methods, Simultaneous gravel seal can effectively cure more than 10cm deep rut, subsidence and other diseases,<a href="http://maintenancemachineprice.com//road-maintenance-machinery/truck-heater-equipment-dealer-in-uk.html">truck heater equipment dealer in uk</a> which is trying to maintain the method can not be compared.</P>
<P>(3) synchronous gravel seal can be used as a low-grade highway transitional pavement to alleviate the serious shortage of highway construction funds; synchronous gravel sealing process is simple,<a href="http://maintenancemachineprice.com//road-maintenance-machinery/tarmac-roller-for-sale.html">tarmac roller for sale</a> fast construction, real-time speed limit open traffic; Road maintenance or as a transitional pavement, synchronous gravel seal performance ratio is significantly better than other methods at the table, thereby greatly reducing the road maintenance costs.</P>
