Numerical modelling in investigation of road failure on Malaysian peat soil
Road failures are prevalent to common pavement distress, involving cracks and surface deformation, principally when it is constructed on organic soil type. Currently, there is no guideline and specification provided in designing a proper road model associated w i t h this problem. Thus, this matt...

| Summary: | Road failures are prevalent to common pavement distress, involving cracks and
surface deformation, principally when it is constructed on organic soil type. Currently,
there is no guideline and specification provided in designing a proper road model
associated w i t h this problem. Thus, this matter has lead to get a concerned from
Pontian Public W o r k Department in order to find a solution of the problems. This
project w i l l focus i n a numerical modelling on a problematic road at Pengkalan Raja
Pontian, Section 41, and K M 48 considering cracks and settlement problems of the
pavement. It deals with comparison between modelling result and remedial
measurement for geotechnical structures. A wide-ranging of field and laboratory
testing were conducted to get an input data into the modelling analysis. At survey
observation, a full scale of cross section pattern will be reviewed to failure
recognizing w i t h the modeling and actual onsite testing. I n conjunction to this matter,
the series o f several trials modelling determining the root cause o f the failures and its
remedies have been successfully conducted to verify the results. P L A X I S V8.1
software program have been chosen for this analysis related to finite element method.
The model complied w i t h actual patterns of the pavement due to failure mechanism,
cause(s) o f failures and probable remedies o f failures for future prevention as well. |
