ABSTRACT
Interlocking paving stone is a good surface material produce as a result of mixture of aggregate to produce a good workability surface.
This research work investigates on how the shapes affect the strength after production. The materials used include cement, sharp sand, quarry dust or granite dust and water.
The structural engineering properties investigated include compressive strength, flexural strength of each types of interlocking paving stone produced that is 3 Star, Double T, Land Roman, Bubble Glover and Didalo tiles respectively. The mix ratio of each stone was also investigated as well as the rate of crushing of the paving stone were noted.
So, from the observation made from this project the average strength of the interlocking paving stone was found to be 5.7gN/mm2 and the highest strength received was found to be that of Bubble glover with a maximum strength of (6.39 N/mm2). While that of Double T (5.59N/mm2), 3 Star (5.39N/mm2), Land Roman (5.30N/mm2) and Digalo (5.19N/mm2)

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.1 Introduction Researchers have work on various materials for paving and method of pavement construction that will provide adequate support for traffic load with minimum construction cost and maintenance. The concept of interlocking stone pavers dated back over 200years ago to the Roman empire where over 800,000km of roads were built using interlocking paving blocks. The roman developed a simple system for building roads some of the roads are still in use today. The roads were ... Continue reading---
CHAPTER TWO - [ Total Page(s): 3 ]CHAPTER TWO2.0. LITERATURE REVIEW2.1 Preamble An interlocking concrete paver is a pre-cast piece of concrete or brick commonly used in exterior landscaping applications. Interlocking paving blocks are installed over a compacted stone sub-base and a leveling bed of sand. Concrete paving stones can be used for walkways, paths, pool decks and driveways and airport or landing docks (Paver, 2012).When one thinks of interlocking paving stones, one often get the idea of dog bone shape stone ...

CHAPTER THREE - [ Total Page(s): 2 ]The following steps were employed in carrying out the test.i. The samples were dried in air.ii. The weight of the sieves were measured with a weighing balance after they have been cleaned with sieve brush.iii. The sieves were arranged in order of decreasing diameter by inserting the bottom of one into the top of another with the largest on the top and the pan at the bottom.iv. A 700g of each sample was measured and poured on the top of the sieve, covered with the ... Continue reading---

Material Tests Performed on the Materials and Samples The adequacy tests for the paving element as a small element pavement include physical dimension, compressive and flexural strength tests. These tests were performed at the Polytechnic laboratory, Ilorin.4.2. Material Tests The test was carried out to determine the amount of water that each material will absorb.Testing Procedure A 200g dry weight of each materia ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0. CONCLUSIONS AND RECOMMENDATIONS5.1. Conclusions Having established the compliance of the paving element produced with standard and specifications, one can therefore conclude that;a. The domineering materials commonly used for manufacture of paving blocks were stone dust, cement and water. b. The materials used for production are of adequate grading, shape and texture. c. The effect of laterite in the mix of the laboratory produced specimens r ... Continue reading---
