A theoretical closed-form nine-slab thick-plate model for analyzing the thermal warping effects in concrete pavements is developed in this paper. It provides the thermal stresses and deformations of a system of nine jointed rectangular slabs resting on a Winkler foundation. It can be used to analyze the effects of nonlinear temperature distribution...
Road roughness indices such as the International Roughness Index, Quarter-car Index, and root-mean-square vertical acceleration are useful as indicators of the level of pavement serviceability performance. Each of these summary roughness statistics offers a convenient index for monitoring the trend of pavement roughness deterioration with time. How...
The development and application of a theoretical closed-form solution of a six-slab, thick-plate model for the structural design and analysis of an edge slab in jointed concrete pavement subjected to vertical loads are described. The jointed concrete pavement system is idealized as a six-slab system resting on a Winkler foundation. The six slabs ar...

Road roughness is normally characterized by a summary index that applies over a length of road. Summary index measures, however, do not retain the actual contents of pavement surface roughness. This paper presents a wavelet transform analysis procedure to offer supplementary information to the commonly used road indices. Its main contribution is to...
Summary roughness statistics are commonly used by highway agencies to characterize road roughness profiles to provide convenient numerical indices for pavement performance monitoring and management planning. Many different roughness indices have been used by different highway agencies worldwide. Unfortunately, since different indices are computed w...
