ABSTRACT
The importance of highway pavement to human progress in terms of movement
and industrialization cannot be overemphasized. Moreso is the importance of the
studied highway connecting the states of Akwa Ibom and Cross River in Nigeria
to the economic development of the people of the states and the country at
large. The danger associated with the use of this failed highway is something
to worry about, yet the necessity to study the situation and propose
sustainable ways to remedying and managing the situation. A field work was
embarked upon to collect samples from the 26 failed portions of the road from
its subgrade, subbase and course layers for laboratory analysis. The
experimental studies which produced multiple results from subgrade/subbase and
course layers showed that the pavement had failed due to poor subgrade and
subbase materials selection on 6 out the 20 points of inference, which failed California
Bearing Ratio (CBR) basic requirement for the layers for Nigerian roads and due
to asphalt bitumen content on all the 26 locations studied. The multiple data
were subjected to Multi-linear Regression (MLR) and Genetics Programming (GP)
based intelligent predictions to forecast possible remedy procedures, the
outcome of which showed that for the CBR models, GP showed prediction accuracy
of over 80% against an error of 16% to outclass MLR while for the MS models, GP
also executed the predictive model at an accuracy of 44% against an error of
16.5% to outclass the MLR, though with a poor accuracy below 80%. This shows
that GP with its robust model execution can be used to forecast the CBR and
Marshall Stability (MS) of the subgrade/subbase and course layers of the
studied pavement as proposed remedy, maintenance and performance procedures to
sustain its use.
