10 selected publications
28th National Convention on Civil Engineering (NCCE 28), TRL69, 1–10
A pavement-strength prediction study relates base materials, repeated axle loads, temperature and season to structural condition. Model outputs are compared with falling-weight deflectometer measurements from actual roads.
28th National Convention on Civil Engineering (NCCE 28), TRL75, 1–6
HDM-4 simulations use Highway 344 data to examine pavement damage and maintenance costs over 20 years for four heavy-truck categories. The analysis supports exploration of maintenance-based truck charges.
Engineering Journal, 26(4), 13–23
Repeated-load tests examined permanent deformation in recycled pavement materials treated with bitumen emulsion and cement. The laboratory results offer guidance for designing recycled pavement rehabilitation materials.
Engineering Journal, 22(4), 39–49
Repeated-load triaxial tests investigate the effect of water content on crushed-limestone stiffness. The measured resilient-modulus behaviour informs mechanistic–empirical pavement design.
Engineering Journal, 22(3), 181–193
Laboratory research examines how crumb-rubber size and content affect asphalt deformation resistance when rubber replaces part of the aggregate through dry-process mixing.
Engineering Journal, 21(5), 315–331
Two image-processing methods separate touching aggregate particles in asphalt cross-sections. Tests against a reference image found that size-based multiple erosion improved particle detection and size-distribution estimates.
International Conference on Highway Engineering, Bangkok, 18–20 May 2012
Investigates semi-automatic faulting algorithms for highway engineering; the institutional bibliography verifies the conference work.
Journal of the Eastern Asia Society for Transportation Studies, 9, 1327–1335
Field deflection measurements and pavement thickness are related to structural capacity to support nondestructive assessment of newly constructed thin asphalt pavements.
Transportation Research Record, 1896(1), 129–137
A boundary-element formulation models layered pavement and temperature-related stiffness gradients. Two Florida pavement examples examine how these gradients affect tensile stresses near surface cracks.
Transportation Research Record, 1832(1), 105–112
Implements a viscoelastic crack-growth law in a boundary-element simulator and evaluates crack propagation in two asphalt mixtures under cyclic indirect tensile loading.
