Fracture the existing concrete pavement in place using pavement breaking equipment with the capa ­city to break the pavement into appropriately sized pieces for removal from the site (the maximum frac­tured slab size for processing in the crushing opera­tion might also be considered at this point).

Pavements are designed on the basis of truck traffic. Without truck traffic, pavements would exhibit only materials-related distress. For new concrete pavement systems, the following loading-related items need to be considered: 1. Design traffic. Most new concrete pavements are being designed for an initial service life of at least 40 years.

 · "Unlike asphalt, concrete tends to have lower price volatility," explains Guo. "That means DOTs can reliably predict how much concrete treatments will cost. This prevents the kind of cost overruns that might occur due to an unexpected increase in asphalt prices." The same tradeoff occurs with pavement performance.

 · –Approx. 1% to 2% passing the #200 from crushing clean concrete pavement –Additional fines come mainly from excavating underlying soils when loading the broken concrete –Gradation specifications should consider: •Underlying material –subgrade vs. treated base •Modify specification as needed (reduce the low end of % passing the #200)

 · Concrete pavements have been successfully executed on slopes of 10 to 12 %. At one time the slope was even 18 %. 33. 33 OPENING TO TRAFFIC Usually, a concrete pavement is only opened to traffic 7 days after the concrete has been laid and after, in the presence of all parties, any possible cracks have been recorded.

IJM India Infrastructure Ltd. Sets a Record of Laying 25.54-km lane in 17:45 hours.
