Road Machinery electrical control systems, especially micro-electronic control unit, after receiving Lightning viewpoint likely to lead to a large voltage damage. Whenever the sky overcast heavy rain comes, lightning often be the construction of Road Machinery frontal attacks, which generates surge voltage can invade and damage the micro electronic control unit equipment
(1) be adjusted paver rammer traveling speed and frequency.(2) hasty adjustment paving thickness (elevation) is.(3) optionally shutdown.(4) of the crawler (tire) slip.(5) pre-elevation not adjusted.(6) leveling instrument sensitivity undesirable.(7) The screed is not in a floating position.
Refurbishment using road milling process can maintain the level of elevation of the original pavement.
The first step: a large number of preliminary investigations. Including surveys of historical data, damaged pavement condition, road structural strength, material properties such as the old pavement. Historical data include viewing the same route survey design, construction, completion, maintenance and repair, and traffic information.
With the large number of highway construction. Semi-rigid material with its excellent engineering class performance and significant economic benefits have been widely used in the construction of highway and road construction increasingly occupies a special importance.
