Alternate Designs by Contractors for Road Bridges facilitated fast track, economic construction of bridges between 1920 and 1980. The first ever bridge in Prestressed Concrete for the Assam Rail Link was completed in seven months (1949). The 3.2km long Sone Bridge at Dehri on Sone was designed and constructed in 33 months (1965)

ادامه مطلبTracked crusher is a stable, safe and reliable crawler type of crushing and screening machine which is excellent for recycling construction waste, asphalt, bricks, and concrete, and other demolition materials, as well as medium-hard natural ore and glass. Transport size, weight, and compact construction make transportation even more convenient, which gives the mobile crusher great flexibility.
ادامه مطلبFor Fast Track to be "Fast", the concrete cover must be removed by rotomilling and the overlay or repair material must be rapid-set concrete. Rotomilling and rapid-set material put the "Fast" in Fast Track Hydrodemolition. Rotomilling removes concrete cover, while crushing and …
ادامه مطلبIt is not uncommon for concrete pavement temperatures to exceed 45 °C (113 °F) in summertime, particularly for fast-track concrete paving (5,8). Mixtures containing certain fly ashes or lower quantities of portland cement can delay early age strength development in cooler weather. Depending on the air and concrete temperature, this could ...
ادامه مطلبFAST TRACK CONCRETE PAVEMENTS "Using fast-track concrete construction techniques, a contractor can often complete a project without increasing crew size or changing normal labor schedules." "To build a fast-track project, both the contractor and agency must make some changes to traditional construction specifications and processes.

ادامه مطلبFast-track concrete rapidly consumes mix water during early hydration and may lead to a larger potential for plastic shrinkage at the surface. Therefore, it is advisable to increase the application of curing compound for fast-track projects to about 3.75 m 2 /l (150 ft 2 /gal). Because deep tining increases surface area, the higher ...
ادامه مطلبThe concrete was initially at about a 6-inch slump visually. This was adjusted to a 4-inch slump by changing the mix water flow rate. It took 17 minutes to place 5.25 yards of concrete. Material was progressively hand-screeded as the placement proceeded. Finishing was aided by using a Sika film as an evaporation retardant.
