Less guesswork. A more efficient use of labor hours.<\/strong><\/p>\n<p>In October, Houston\u2019s Bush Intercontinental Airport for the first time used \u201cstringless paving\u201d technology at our Taxiway WA\/WB Rehabilitation Project.<\/p>\n<p>\u201cString lines have traditionally been used to control paving machine elevation and grade steering,\u201d explains Houston Area Manager Mike Zanella. \u201cStringless paving, also known as 3-D paving, is an innovative process where noncontact electronic guidance systems are used.\u201d<\/p>\n<p>In stringless paving there are no pins, hubs, sensors or other devices previously used to guide paving. \u201cThis produces significant savings in time and labor,\u201d says Zanella. String-guided paving typically requires five feet of&nbsp;[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_single_image image=&#8221;5940&#8243; img_size=&#8221;medium&#8221; add_caption=&#8221;yes&#8221;][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text]clearance on each side of the paving machine. With stringless paving, that is reduced to as little as a foot, providing easier access for workers and trucks.<\/p>\n<p>There are three major parts to the process:<\/p>\n<ul type=\"disc\">\n<li>Developing the pavement surface model(s). Bush Airport\u2019s engineers provided Flatiron with the models to use for the paving.<\/li>\n<li>Transfer of the model(s) to the paving machine\u2019s onboard computer.<\/li>\n<li>Establishment of survey control points along the paving zone. A series of total stations and\/or GPS systems communicate with the software to guide the paving machine.<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_single_image image=&#8221;5941&#8243; img_size=&#8221;medium&#8221; add_caption=&#8221;yes&#8221;][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text]<b><br \/>\nStringless paving also makes the site safer for workers<\/b><\/p>\n<p>\u201cThis technology enhances safety on the grade by reducing or eliminating trip hazards from hubs, stakes or the string itself,\u201d explains Zanella. \u201cIt also improves access to the grade in front of the paving machine, reducing choke points and other dangers from delivery vehicles backing up to the paving site.\u201d[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_column_text]&nbsp;<\/p>\n<p>&nbsp;[\/vc_column_text][vc_single_image image=&#8221;5942&#8243; img_size=&#8221;medium&#8221;][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text]Those aren\u2019t the only benefits to using this innovative technique. \u201cString lines are constantly at risk of sustaining damage that can affect paving accuracy,\u201d Zanella explains. \u201cThey get moved around for different operations, for example. Weather can also make the strings (actually fine wire) expand and contract.\u201d The lines require frequent maintenance to function properly. Stringless paving eliminates the need for that.<\/p>\n<p>Finally, there\u2019s a sustainability angle to using stringless paving. The software is more accurate than string, meaning less risk of wasted concrete.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text]Use of software-guided paving systems bring host of benefits[\/vc_column_text][\/vc_column][vc_column][vc_video link=&#8221;https:\/\/vimeo.com\/642512173&#8243;][vc_column_text]&nbsp; &nbsp;[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_column_text]&nbsp; &nbsp; &nbsp;[\/vc_column_text][vc_single_image image=&#8221;5939&#8243; img_size=&#8221;large&#8221; add_caption=&#8221;yes&#8221;][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text]&nbsp; Safer.
