Analytical Methods for Deriving Work Zone Capacities from Field Data
- Abstract: Praveen Edara, Jalil Kianfar, and Carlos Sun Work zone capacity is a key variable in scheduling construction activity on roadways. Understanding the effect of different definitions of capacity on the values computed from field data will result in better planning and scheduling of lane closures. Capacity values obtained using three different de ... [J. Transp. Eng. doi:10.1061/(ASCE)TE.1943-5436.0000374] published Fri Jun 8, 2012.

Deceleration Lengths for Exit Terminals
- Abstract: Kay Fitzpatrick, Susan T. Chrysler, and Marcus Brewer General freeway design practice assumes deceleration for a vehicle exiting the freeway occurs between the point when the vehicle clears the through-traffic lane and the point of limiting design speed for the ramp proper. The length provided between these points should be at least as great as the dis ... [J. Transp. Eng. doi:10.1061/(ASCE)TE.1943-5436.0000380] published Fri Jun 8, 2012.

Determination of Damage Development in Asphalt Concrete Using Small-Scale Accelerated Pavement Testing via Frequency Domain Analysis Approach
- Abstract: Sudip Bhattacharjee and Rajib B. Mallick To predict the pavement response correctly at any condition, the constitutive relation between stress and strain will require the use of a damaged modulus. Several asphalt concrete slabs constructed in the laboratory using vibratory roller compactor and instrumented with strain gauges and thermocoup ... [J. Transp.

Hierarchical Markov Chain Monte Carlo Simulation for Modeling Transverse Cracks in Highway Pavements
- Abstract: Leslie N. O. Mills, Nii O. Attoh-Okine, and Sue McNeil Transverse cracks are distresses whose initiation and propagation affect the stability and structural integrity of the highway pavement. They are caused by load, moisture, temperature, construction defects, or a combination of these. Cracking leads to inherent pavement defects that are exacerbated b ... [J. Transp.
