Analysis of the Method of Erosion Control on Highway Construction in Sapele Road, Benin City, Edo State, Nigeria, using Pearson Product Moment Correlation Coefficient

Abstract

This study is on Analysis of the method of erosion control on highway construction. The Pearson product moment correlation coefficient (Pearson r) was used to analysis the results. A total of twenty-two (22) question were carefully and scientifically developed from the method of erosion control on highway construction. A total of one hundred questionnaires were distributed to staffs in the Ministry of Infrastructure, Benin City (Sapele road) and surrounding residents. reliability tests of the experiment was done from the data gotten from questionnaires distributed to staffs (X) and residents (y). From the results and data analysed the Erosion level measure shows that the erosion existing in Benin City is very high, there is exists a strong correlation between the responses from employers and those residential quarter form the questionnaire analysed, the valve of r= 1.5  from the pearson correlation coefficient showing a strong correlation between the respondents. from the results of the study from the pearson product moment correlation value (r = 1.5),confirming that exist a strong correction between the response of the employees and residents. The findings of the research showed that erosion causes a lot of damage to highway construction, also long duration of rainfall was also an issue, recommendation was drawn, there should be government regulations to employ the cleaning of drainage by enforcing a series of rules and laws to govern it. Lastly  proper supervision of highway and drainage construction to reduce collapse of pavement.
