In an attempt to find a mix design where quarry dust incorporated, optimized combination of cementitious and aggregate materials has been developed which contains cement, sand, quarry dust and chips in intended for the production of interlocked concrete blocks paving in road pavement. The main purpose was to achieve optimized Concrete Blocks with fulfilling the requirements in road by using different aggregates, admixtures along with the economical production cost via materials. The analysis has indicated that the use of quarry dust instead of sand is more effective, since it is possible to include a higher percentage of quarry dust in the dosage (80% of the weight of fine aggregate) maintaining the required compressive strength in 28 days, higher than 50 N/mm2 (50 Mpa) for W/C of .30 while maintaining the shape and the surface texture. Therefore, non-conventional pre-cost block with the possibility of being extensively of being extensively used in urban and rural road networks represents contribution on standardization and economical aspects
