Lets see how did we evolve and where we are going with road construction
Wednesday, March 5, 14
Past, Present & the Future of Road building in a Snapshot The Past – Make it black & don’t look back
– Production was primary objective– Few agencies with smoothness specs– Lenient density specifications– PWL (% within Limits) or uniformity specs non-existent– Segregation problems (mechanical, thermal, both) on many projects
8
Wednesday, March 5, 14
The Present - Produce long-life pavements– Industry “best practices” used to achieve uniform high density, smoothness and
longer pavement service life– More stringent density specifications– PWL and uniformity requirements exist– Most agencies have smoothness specs– Segregation measured and penalized
9
Past, Present & the Future of Road building in a Snapshot
“Earn density and smoothness incentives; produce long-life pavements.”
Wednesday, March 5, 14
The Present– Performance - the main objective– Uniform density across pavement width and through depth of complete pavement
structure– Homogeneous material texture to mitigate noise– Optimum pavement surface smoothness for superior ride ability– Durable pavement structure for longest service life and lowest maintenance cost
10
Past, Present & the Future of Road building in a Snapshot
Wednesday, March 5, 14
The Present – Workers Safety & Care for Environment– Agencies specify safety on work sites– Contractors provide workers with safety equipment– Industry promotes motorist and roadway worker safety programs– Worker safety designed into today’s machines– Fumes control– Night lighting Balloon lights HID (High Intensity Discharge) lighting on mobile equipment LED (Light Emitting Diodes) lighting use
11
Past, Present & the Future of Road building in a Snapshot

Intelligent Paver
1)Knows how mush asphalt to put down and how many trucks coming at what interval2)Adjust the paving speed automatically3)Paves according to the Road Plan fed remotely ( 3D Paving)4)Sends Location, Speed, Density and temp data via GPS back to back office5)Send the same data to following breakdown roller
Intelligent Plant
1)Real time data on Mix delivery 2)Sends the location and availability of mix to the paver real time3)Entire truck fleet is automated with plant and the paver
Intelligent Rollers
1)Receives paver data2)Decides Rolling speed, # of passes , Frequency and amplitude3)Performs compaction accordingly4)Sends the Mat Density and Temp real time to back office and also following intermediate roller5)Intermediate roller works accordingly and becomes information agent for finish roller
All process is connected via telematics and monitored from remote control room
