Pavement Analysis

Pavement design primarily adheres to either the AASHTO method or TxDOT FPS method. The suggested pavement sections are tailored to meet city or county guidelines and are influenced by anticipated subgrade soil conditions. Pavement design also includes ways to mitigate the movement potential of the underlying expansive soils. Both rigid (concrete) and flexible (asphalt) pavement designs are presented for a range of facilities, including:

  • Residential streets, including local, collector, and arterial type streets
  • Commercial pavement and parking lots

InTEC presents a range of pavement options, allowing the owner to select the one that aligns best with the project requirements. These options include various subgrade stabilization methods, such as:

  • Lime stabilization
  • Cement stabilization
  • Use of 3x5 rock
  • Use of geogrid

Frequently Asked Questions

Pavement design
  • A pavement system for flexible pavements includes subgrade, aggregate base, and asphalt, while rigid pavements consist of subgrade, base, and concrete.
  • Site soil conditions, input parameters, and design methods collectively contribute to determining the thicknesses of different pavement sections.

Notes on Pavement Analysis
  • In South Central Texas, the pavement distresses are common
  • The pavement distresses are due to change in moisture content of the underlying subgrade or aggregate base
