1.1 A Different Kind of Concrete

Roller Compacted Concrete or RCC, takes its name from the construction method used to build it. It is placed with conventional or high-density asphalt paving equipment, and then compacted with rollers. Roller Compacted Concrete has the same basic ingredients as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone. But unlike conventional concrete, it’s a drier mix-stiff enough to be compacted by vibratory rollers. Typically, Roller Compacted Concrete is constructed without joints. It needs neither forms nor finishing, nor does it contain dowels or steel reinforcing. These characteristics make Roller Compacted Concrete simple, fast, and economical.

1.2 Roller Compacted Concrete Pavement Performace

   1.2.1 Smoothness

Pavement smoothness is particularly important for a Roller Compacted Concrete project, and also for economy the following steps can be taken to improve the final results:

If high-speed traffic operations are required, a thin 50 – 75 mm (2-3 in.) layer of asphalt or bonded concrete can be placed over the Roller Compacted Concrete slab to provide a smooth traveling surface. Diamond grinding of the Roller Compacted Concrete surface has also been used, and can provide additional smoothness without the construction of a surface overlay.

1.3 Objective

The objective of this research was to construct a test cube for economical Roller compacted concrete. Specific topics to be investigated include:
Determine the appropriate proportion of 12 mm size metal and dust in Roller Compacted Concrete.

Representative APR 391%. Average APR for this type of loans is 391%. Let's say you want to borrow $100 for two week. Lender can charge you $15 for borrowing $100 for two weeks. You will need to return $115 to the lender at the end of 2 weeks. The cost of the $100 loan is a $15 finance charge and an annual percentage rate of 391 percent. If you decide to roll over the loan for another two weeks, lender can charge you another $15. If you roll-over the loan three times, the finance charge would climb to $60 to borrow the $100.

Implications of Non-payment: Some lenders in our network may automatically roll over your existing loan for another two weeks if you don't pay back the loan on time. Fees for renewing the loan range from lender to lender. Most of the time these fees equal the fees you paid to get the initial payday loan. We ask lenders in our network to follow legal and ethical collection practices set by industry associations and government agencies. Non-payment of a payday loan might negatively effect your credit history.
